Usb host on dell streak

Looks like the streak might have usb host... if you look in the sdcard settings it has the option to unmount ums (usb mass storage) devices and the option to format them.
Im on the 8105 2.1 o2 rom on a us att dell streak.
Ill make a cable soon to test but was wondering if anyone else tried th already

If the option can be found in 1.6, I may already have the hardware to test it.
This would be a beautiful thing!

I just so happened to have the correct hardware on hand to try this so I gave it a go, looks like it does! I'm actually typing this message with a USB keyboard- I can't get it to mount a USB drive yet, but I intend to brush up on my Linux commands and syntax tomorrow and try again- if I can get it to mount external storage, all of my dreams have officially come true (minus the Froyo, that is).
Edit: I'm on the MoDaCo custom ROM r2, 2.1 build 8105, for those interested.

Hey there, real interested in what you did to mod your cable to handle this. Was it a matter of tying the OTG pin to ground?
Did the streak supply power over usb? Many android devices cant, but I believe given the right cable mod the streak can.

I didn't have to do any mods on mine, I have the home dock (which converts the Streak's port to miniUSB) and a dongle that has male miniUSB on one end and female standard USB on the other. Streak on the dock, dongle in the back of the dock, and keyboard into the dongle.
I don't know if it supplied power or not, what would be the best way to check? Multimeter across the power/gnd should give 5V regardless of if it's powered, do I need to check the amperage as well? I was thinking I might just try firing up the ol' G1 and plugging it in, to see if it charges.

A good test would be to not have the dock plugged in to any power source. Dock your Streak, then use your adaptor with USB keyboard. Does it work? if so, the power is being supplied by the Streak.
If not, it doesn't prove that there is no way to get powered USB host out of the Streak, it would just show that it may require different connections (a modded cable or dock).

Then yes, it supplies power, my dock was unplugged the whole time. Rejoice! I foresee emulators with a USB gamepad in my near future...

That's great to hear! Game controller for EMU's is what I'm looking to do with it as well
Funny though, I tried the same with a gender changer a week or so ago and it didn't work for me. I think the difference must be that the cable you're plugging in to the dock must ground the OTG pin.
Unfortunately that probably means I'd either have to get a dock, or dissect and solder my USB cable to get the same.

Glad to see it works as i suspected. now all we need is some to make it mirror the display over the hdmi out

Ah, I wondered what that meant. I have the home dock and saw Win7 did something funny... it's all a bit beyond my abilities so I look forward to someone doing interesting things with it

how can we make a usb cable with "usb host" feature ?

EiHter using the media dock with a male mini usb to female usb adapter, or i think using the standard usb cable with a female to female adapter placed on the end should work too.

Unfortunately I don't think a female to female adaptor alone will do the trick with the Streak USB Cable. I have one here, and it's not working.
I believe the reason is the USB OTG pin needs to be grounded to identify that we are in USB OTG mode (pin 4 as identified here http://en.wikipedia.org/wiki/PDMI).
I think the reason it's working with the dock for that person is because the dock exposes that pin at the mini B port and the cable adaptor he's using is an OTG cable that grounds the pin.
I haven't tried modding my cable for this yet, but will soon. My soldering iron is in storage right now unfortunately.

Ok; I understand that we have to connect OTG pin (no 4 on PDMI) to GND (no 2 on PDMI)
Is that correct ?
Is there a way to do it on the other end (not the PDMI side but USB side) ?
Because I don't want to break my only Dell Streak data cable...

Unfortunately, no. only 4 wires run through the cable and are exposed at the other end. You would need a 5th (the USB ID, aka OTG lead).
So I just finished creating my own modded cable and it is working great.
I've attached pictures of the build here. I found that this only works in Android 2.1 (8150 build for me, may work with other 2.1 builds). 1.6 seems like it doesn't have the drivers for this.
DISCLAIMER: If you try to duplicate what I did here, you're taking the risk of damaging your cable beyond repair, and if you do something incorrectly and plug the cable in to your Streak, there is a definite possibility you will damage your streak permanently. So anything you do, do so carefully and at your own risk!
I will say this; this cable is HARD to de-shield! It has metal shield all around the parts we need to get to, and I had to cut with metal clippers and desolder parts of it to get the shielding off. Not pretty, and pretty risky for damaging the cable. I would advise you buy an extra cable before trying this. I didn't have an extra, but I was really risking not being able to charge my device or something if I broke my cable.
After removing the shielding you can see that there is a small PCB with traces marked 1 3 on the left, and then 2 5 on the right. These correspond to the PDMI specification at http://en.wikipedia.org/wiki/PDMI .
For my build, I chose to solder a switch to bridge the OTG pin 4 to GND pin 2. This way, my cable can still be used as a normal USB cable as well. In one image I have flipped the opened PDMI connector over and you can see an orange wire I have soldered on to pin4. (One side of the PDMI connector has ODD pins, like 1,3,5,7... the other side has EVEN 2,4,6,8...). Pin 2 is the first pin on the right on the EVEN side, and pin 4 is the second.
As was stated in earlier posts, you can use a female to female gender changer for the other end of the USB cable, rather than soldering on your own connector or something.
Note that having the cable in OTG mode when plugging your streak in to your computer or power adapter over USB could damage something because OTG mode will start outputting power over the same pins that it's usually inputting from!!!

0TheRain0,
This is great !
Thanks for sharing your findings.
I sent you a PM; please check it when you have time...

When I built my Dell Streak Mini USB adapter, I brought out PDMI pin 4 to the OTG pin on the Mini USB.
I tried it with 2 different cheap Mini USB to Standard USB ("A") female adapters, and tried several devices including a Apple Mini Keyboard/Hub, and USB Flash drives.
I also tried the same components on the Dell Home Dock.
They did not work, but I suspect that the Mini USB to Standard USB female adapters do not short the OTG pin to ground.
What we need is some that do. Then it would be plug and play at least for dock owners.
Edit:
These claim to enable USB host mode when Connected to a N800:
http://www.electronicproductonline.com/catalog/product_info.php?products_id=2043
Therefore Should require no modification to use with the dock, as long as the dock brings out pin 4, which as far as I remember, my testing said it did.

This thread is currently of great interest. Should it, in theory, be possible to hook up my Canon digi SLRs as mass storage devices then?
Sometimes being able to get the image onto a bigger screen has it's benefits. The Streak's screen is actually very well calibrated as well, compared to my hardware calibrated monitor!
In the ideal world i'd be able to tether and shoot using the streak (like I can with my laptop) but I'm realistic and know that's not likely to happen!
What I DON'T get is why Dell have put in USB host functionality without implementing it in the lead?

Well, I was going to hold off on cutting up a cable to try something, but I just had a cable go through the washer and dryer... and it was looking pretty bad and actually cut through the jacket and shielding on the wire... so I cut off the PDMI lead and about 3" of cable (right before the break).
Inside the jacket are 4 wires. Black, White, Green, Red. Obviously they correspond to the USB 2.0 spec... so I guess in some way, VDC, Ground, Data+, Data-... but no OTG wire.
Would anyone that opened up the connector know how these wire colors correspond?
What I really want is for my 80GB iPod to have it's music available to the Streak in my car, so here's what I was planning:
1) Cut up the Dell PDMI cable (done).
2) Cut up an old iPod to Firewire cable I have laying around
3) Splice VDC+ and Ground on the iPod and PDMI to the corresponding VDC+/Ground USB end of the original Dell Cable. This will plug into a 12V->USB Adapter (probably the Dell one) to power and charge both devices.
4) Splice the corresponding PDMI and iPod data transfer wires.
5) Ground OTG on Streak side and add a micro switch, like TheRain did...
I can then wrap this up in some custom cable thing shround thing that I'll figure out.

Little bit of research led me to the micro-AB receptacle that basically determines if a device is acting as a host or slave. So, I would say the preferred way to do this, instead of wiring in a switch, would be to find a receptacle and hack into it... so here's one you can get cheap:
http://www.retractablecables.com/US...ro_AB_Female_Adapter_for_USB_OTG_Devices.html
This should be able to wire up something that basically puts the device into OTG mode when you connect a micro-A cable to the device, and a slave device when you connect a micro-B cable.
So solder/wire that up.. connect the Streak with a micro-A cable to a powered USB hub, connect the peripherals to the hub, and you should be good to go without a micro switch.
On an edit note, I also found a bare micro-AB female that you can buy... but it's more expensive than the previous adapter, so uh I guess it depends on how much time you want to spend tearing the adapter apart.

Idea for permanent host-mode switch...

Got the idea a few days ago after looking at the full breakdown of the Xoom...
Here's the idea:
Remove the dock charge contact points, and install a micro switch in its place. With the switch in place, find the proper contact points for ground and the host-mode pin on the micro USB port. Solder some 30 AWG to the contact points on the board, then to the switch, and put everything back together.
This would give you the ability to use any USB cable as a host-mode cable, while only affecting charging on docking units. With the battery life of the Xoom, I don't see it as a deal breaker.
Thoughts?

Well, I only charge on the dock. Way to convenient not to have. I don't trust the standard chargers design to withstand me..
However if you are not a dock user, then it sounds like it would be cool.

Just my opinion, but it seems like a lot of risk and effort for not having to carry around a cable. I mean if you have the standard cable, you still need a male to male adapter to use any usb device. So either way you still need something else besides the standard USB cable. I would rather just have a USB host cable that already has the correct USB ends on it and still be able to use my charging dock.
Again just my opinion, YMMV.

Well normally I'd agree with you, but it seems that most people are having issues getting good cables unless they buy the Motorola cable.
It's easier to find an adapter for the standard USB cable than it is to find an OTG cable as well.
Still just an idea, but I figured I'd see what everyone thought.

all you need is the Motorola Mini-USB to Micro-USB adapter, a USB extension cable and some scissors.
you'd to still carry around a Female-Female adapter for your USB cables with your idea, i'd rather not rip open my xoom and solder **** when the other option is easier.
Also, if you don't plan on upgrading to LTE, you could just wire up a USB port to the card slot for the LTE card, it should have USB routed to it.

This actually sounds like a better idea... Was thinking of how I could add in a full-size USB port to remove the extra cable completely. USB out the top would also allow me to hook up an external HDD and still sit the Xoom up in a cinema position.
The question with doing that though, is will it be recognized as a host-mode connection, and if not how would you get it to act as a host-mode connection without the 'fifth pin'?

[Q] run music on nook simple touch

hello guys , i know u can play music on nook simple touch ..... but i am asking about if i can use Samsung galaxy s3 headphone and connect to my nook .... it will run on it ....and if not .... what pins i must modified
i just want put direct headphone .... no usb jacks
thx

Sorry, you'd need an audio interface on USB somehow.
Maybe you could hack it internally but it would be a headache in one way or another.
The system-on-a-chip does support an interface to audio chips but you'd have to do a lot of work to get that going.

The micro USB connector is used for a lot of things.
The five pins on it can be used for unrelated things if the hardware behind them supports them.
The options are
USB
CarKit (analog audio in and out)
MHL (HDMI-like video interface)
UART (logic level serial port for debugging)
Unfortunately, on the Nook we just have USB.

You need an USB OTG adapter cable (brand, model not important, but it must say "OTG").

I find those easier, although it's hard to see from a photo
if it goes left or right out of the socket.

Would it be possible, with some software modification in NST, to use something like this1, instead of a huge USB audio adapter?
or this2 or this3? Or best of all, can I simply use microUSB headset? like this

Nope, those adaptors will not work.
They are all just mechanical adaptors with no active electronics in them.
A micro USB connector is often used for multiple things, USB, MPL, UART, analog audio.
Inside the device these things must be supported.
Motorola handies often allow the sending of analog audio through the micro USB connector.
You only need a mechanical adaptor to be able to plug in headphones.
The Nook has no audio hardware inside.
You need an actual USB audio adapter.

Thanks mademoiselle Renate!
My ideal plan: dig into NST and hide the good microUSB/USB sound adapter inside the Nook case. and just leave the microUSB cable outside. Do you think this is possible or just a childish dream?
Better: is it possible to extend 1 microUSB to multiple? like an extender. Any consequence on battery use?

You could connect a USB device inside a Nook.
For any audio adapter it would be best to just put in a separate headphone jack.
The problem comes when you want to use the Nook as a peripheral.
If you use an internal hub then everything has to switch direction.
It all gets complicated.
Hubs are kind of power hogs since they are usually on wall powered devices.
Since the OMAP3621 is designed for an audio interface, that would be a challenge but would use less power than a USB solution.

That would be interesting to see, I think your gonna need drivers for that as well because your gonna need a switch to cycle back and forth on what connector your using, and thats gonna be hard to do from scratch. I was contemplating doing something similar to that but wound up at a dead end. If you figure it out let me know.

it won´t need a driver. i want to build as a host hub. but the current is too low i think, so it is difficult to stabilizise the current,,

It's not a question of stabilizing the current.
It's supposed to be 5 volts throughout the USB spec.
If you are using a cell phone as the host, that already produces regulated 5 volts through a charge pump.
The amount of current out of a cell phone is maybe around 100 mA.
That's what you have to work with.
If it's not sufficient for what you want then you need an external power source, not a regulator.
Hubs can be power hogs.
The spec says that a hub can take up to 100 mA all by itself.
To make a micro USB you can either take an existing hub and change the connectors.
Of course since the PCB pattern will not match up you'd have to wire the connectors in discreetly.
If you really wanted to make a real job out of this, buy a hub IC for $3,
lay out a PCB, slap on a 24 MHz crystal and connectors.

???
the idea is to build an mobile hub for tablets or smartphones for plugin external devices like sd card reader or usb stick and
mouse and keybord. hub will stick in a phone and plug in the external devices. i already had tried with a keyboard and mouse with standard usb and it works. i had already build some devices with micro usb connector. so i would like to use all devices at the same time and outdoor. i try to solve the idea without a lot of adapter..
if the usb give all devices 5v and 100mA at the same time, that would be great, without an additional IC power supplier..
thats all

i found out thats not possible to use more than 2 gadgets at the same time cause of the voltage without an external power supplier. keyboard and mice work at the same time but i f u want to plug in a 3rd gadget then wont work. 1 solution could be a mobile battery with 5v connecting with the hub. or make a built in battery in the hub..
@ renate. maybe u have an suggestion?

I have a jig for measuring current consumed by USB peripherals: http://forum.xda-developers.com/showpost.php?p=30668417&postcount=26
I use USB with only low power things like a keyboard or else
with a powered hub (also back-powering the Android).
The second option is more like a docking station.

The 2 female connectors don't make much sense i think, because:
I can't think of any device you would like to connect with your phone as host that has a µusb connector..? You would need 2 additional OTG-cables in almost all cases
You would need OTG capability for security reasons: Imagine you hub is pluggend in you phone and you connect you computer to the hub too -> Data crash + 2 power sources in parallel -> risk of damage
I would use a normal tiny usb hub and only change the cable

u did not read my post above attentively or?

USB OTG a few things tested...

I've no idea if this will be of interest to any of you, especially those people who have yet to buy a 5t and are trying weigh up the pros and cons, but USB OTG is something I use all the time, so o it was one of the first things I tested when I got mine. So far I'm really pleased as everything I wanted to work does so. My last device, a Xiaomi Redmi Note 2, had very poor USB OTG implementation so this is great from my point of view. Maybe I'm behind the times and I had the last phone on the planet with that problem - if so, please delete this mods
First off, before you can use USB OTG, you need to head into settings, then advanced and check the OTG setting. It turns off after ten minutes so I created a link on my homepage using Nova launcher's activity widget menu.
*EDIT* As ny-hardcore has kindly pointed out below, you can also have an OTG quick toggle in notification area. This didn't work for me at first (or I was hitting the wrong thing), but now it does .
Tested and working:
USB card readers of various types, including micro USB readers, with the help of a USB C to Micro USB adapter (5 for £4 on eBay!). The only one that didn't work is a proprietary Samsung multi card reader that also has a full sized USB output and HDMI out too. This isn't very surprising of course, but they're to be avoided if you see one on eBay and assume it's a generic adapter.
80 GB iPod hard drive in a cheap enclosure bought via Amazon.
1 TB 2.5" Western Digital HDD - that's right, no USB hub required, just plug it straight in. The only other portable device I've owned could power it was a Samsung tablet.
2 mega pixel boroscope (using USB Camera app in Play Store) . So useful for finding slow water leaks under the floor or peering down a spark plug hole into a cylinder!!
Micro USB DVB TV dongle, via adapter.
Keyboards and mice via an OTG adapter, including a combination media keyboard with built in trackball mouse (this usually doesn't work on my phones for some reason). The UK keyboard layout is supported via settings so you can have a £ key - woohoo!
Other phones! I plugged my old phone in and discovered I could mount it in MTP mode and then browse its contents from the built in file explorer. For what it's worth, the Oneplus even charges the device that's connected to it.
When you need to eject the device there's a button that appears in the notification area. Sometimes this gets obscured, so swipe down a second time and the 'eject' will appear.
I haven't tried any game controllers yet, but so far the support has been so comprehensive I don't see why there would be a problem.
In the attached photo, the only thing that doesn't work is the black coloured multi purpose card reader on the far right.

In quick toggles you can add an otg switch.
You don't have to go in settings that way to enable otg.

Thanks, for some reason that just didn't work for me unless I went into settings/advanced as well. I can't recall which firmware I was on at the time and I haven't tried since The quick toggles are so far away for my little hands too (please Oneplus add a Xiaomi one handed mode - in fact, make it EXACTLY like Xiaomi devices).
LOL, typical, now it does work for me! I was probably pressing flight mode by mistake or something.

Just FYI, I've tried the following USB DACs with an OTG cable on my 5T and they appear to work:
- Fiio E17
- Meridian Explorer (v1)
- Audioquest Dragonfly (v1)

I just discovered my old Saitek X35/X36 throttle/joystick combo works too! That's a first for one of my Android devices too. Now I need something fun to test it with

Has anyone gotten USB sound cards to work *for recording*.
Like I have a Terratec Aureon USB MkII and would like to livestream my DJ sets to Facebook via the FB app, by hooking up the line-out on my decks to the line-in on a soundcard hooked up to my phone and have the streamed video use the soundcard instead of the internal mic which sounds rubbish.

That would be so cool if you can get it working. Wonder if it's the phone or the Terratec? I have NO experience in that area. Good luck! How much power does it draw? Would a powered USB hub in the mix help?

Hadn't thoughtof the power draw issue.
What I really need is a super cheap low power USB line-in of some sort. Though after further testing, FB live streaming is crap, with low quality audio and video in all the configurations I tried (Android app, Win10+Firefox, Win10 app) so I'm probably going to abandon this plan and try a different platform like Youtube or something.

Just cant get otg to work in my device, I am on OOS 4.7.5, rooted with SuperSu, tried a type c to micro USB adapter, also a type c to USB 3.0 adapter, I have enabled the otg option in advanced settings before plugging in the devices, I don't know whether its the phone or the adapter I use, what kind of adapter did you buy, is it a type c 3.1 to micro USB 2.0/ USB 3.0, could you provide me with a name of the adapter.

I have the following USB OTG adapters.
2 X micro USB to full sized USB (the long type with a two inch cable).
1 X mini micro USB adapter that is tiny.
1 X micro USB adapter (bigger than above)
1 X USB C OTG adapter with micro SD card reader built in.
All of the above work. In the case of the micro USB OTG adapters, I'm using a USB C to Micro USB adapter (they're tiny, about 2 CM long).
In short, every USB OTG adapter I've put in it works. All are unbranded, generic adapters that I've bought from Amazon or eBay. I've never had to do anything more than enable OTG in settings.
Could it be something to do with the ROM you're using?
In the attached photo, the ones with a yellow Mark are micro USB OTG adapters. The one with a red mark is a USB C multi card reader (built in USB OTG). The one with a blue mark is a USB C to Micro USB adapter.

Sadly what you're doing is way beyond anything I've tried. I'm happy when I can get card readers and stuff to work
I vaguely recall reading about specifications for the older micro USB ports on phones and what type of power output they supported - not all were equal. For example, there were a bunch of Samsung phones and tablets that could power hard drives without needing a powered USB hub inline. Similarly, some could power an MHL connection to a TV without the adapter being plugged into a charger like most phones that supported MHL had to. I've forgotten the name for these specs, but presumably USB C is exactly the same and it'll be online somewhere. No idea what your Terratec draws or if that could be the problem - if our phones can spin a 1 TB hard drive then perhaps it's not an issue, I was just clutching at straws.
Good luck!

4.7.4 Stock. Stock recovery too (not rooted either).
USB OTG worked on stock 4.7.2 as well.

Working fine for me, stock, custom roms etc. Use a cableconnection usb/otg cable 6" in length. Just enable OTG in the swipe down, plus USB stick in...no problems.

I gave up on using the phone for this because the audio quality via the FB app is terrible anyway, so I nicked my GF's Windows laptop and started using OBS for streaming instead.
Power aside, it's awesome that an external sound card will work (kinda) for recording though!.

On which ROM version are you on, is OOS 4.7.5 or another version of OOS or some other ROMs.

Thanks for the reply, I am beginning to think that it kind of an issue with OOS 4.7.5, I have to flash the old version and try my luck on it.
