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

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.

Hi,
I made my own usb otg adapter from a plain usb a to micro b adapter. You have to connect pin 4 /which is not connected/ to ground to fire up host mode.
Edit: It is not easy to dismantle a usb connector or adapter and it requires soldering. So I guess anybody with the necessary skills will find the pin on his own. I will not post photos because my solution is far from being pretty.
For everybody else: the nokia USB OTG cable is wired the same way so it is very likely that it will work. (on Hungarian forums I saw references that it works, but I can not guaratee it.)
Tommorow I will go buy one and report.
USB Host mode will allow to connect USB pendrive, mouse, keyboard etc. to the SGS II.

this is very useful for people like me who knows how to solder things, but for the people who have absolutly no Idea what you are talking about, you should add more details/pictures to the OP so the people who doesen't know much about electronics know what you are talking about, and what benefits it brings for them.
I myself will probably make one or more, so I don't have to always take my USB OTG with me all the time.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries
As one knows, Samsung has promised a HMI Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !
Instead of shorting pin 4 and 5 from within the cable head, would it also be viable to short them from within the device itself? Say if I disassembled the phone to access the back of the female usb micro connector and soldered the pins. Would there be any damage caused if the permanently shorted pins 4 and 5 (within the device) is connected to a charging adapter/PC?
Hi, everybody.
i just buy a samsung galaxy tab 7.7 and just noticed only can be charged by using the power socket provided by samsung.
now i found a way to charge your tab by your laptop or PC through samsung STANDARD USB DATA CABLE cable.
First, download the software (ASUS Ai Charger) attached:
Second, just install and enjoy to charge your tablet through use cable.
FYI, battery indicator still showing no charging but actually it is charging.
you can check after one minute by viwing the remaining power up.
Thanks.
Is this software just raise yr usb port mah to certain amount?
If so, will this harm the computer?

My tab charges when plugged into my computer without that (or any similar software, only Kies and AOSP USB drivers installed). It doesn't show charging but the charge definitely goes up. Does that software actually make it charge faster? I have to say, I'm pretty dubious.
I would recommended getting the following adapter, I originally bought it for my original tab and was able to charge via the laptop with no problem. It charges as fast as the wall charger.

Thanks for the info.
Though it must be noted that you need an Asus motherboard for this, my Gigabyte provides 1A front USB ports thats where I charge the Tab7.7 I'll try if there is any difference real world difference if I plug it into one of the regular USB ports.
I accidentally found out I was able to charge from my Mac without using this special software as follow:
I bought an external battery, New Trent IMP99D (Amazon Link) and it came with a special USB extension cable (picture below) that is designed for the Tab 10.1. If I plug the GT7+ directly to the IMP99D without using the extension cable, NO charging takes place. However, if I use the extension cable, charging works.
I connect the extension cable to my MacBook Air, connect the GT7+ charging cable and the tablet and... VOILA.. it's charging! HoneyComb even reported that it is an "AC Charging" and it charge pretty fast.
So you can either
a). Buy the battery and it comes with the cable
b). Buy JUST THE CABLE, model IMP44B (manufacturer link here)

I was wondering if anyone is having similar issues with aftermarket cables.
I bought 2 cables that work fine in 2.0 for charging/data transfer.
When I put them into a 3.0 ports nothing happens, there is no prompt to access the phone, and the USB options do not appear on the phone.
I have downloaded the Samsung drivers, and tried 2 different PCs.
I have no issues using the provided Samsung cable.
Any ideas?
I haven't experienced this. Actually, I think the Samsung USB 3.0 cable that came with my phone was bad. When I used it, USB 3.0 would stay grayed out. I had another one for a portable hard drive and that one works fine with the phone. Maybe just try a different brand. These cables seem rather fragile.

I purchased a 9ft Amazon Basics USB 3.0 cable and all is well. Connecting through a USB 3.0 port, my device was immediately recognized, and I had no problem transferring data files to and from the device.
My only guess would have been to ensure that your PC's USB 3.0 drivers are installed in order for the ports to work properly. Since you're not having any issues with the stock cable, I'm not really sure.
I don't know if it'll make a difference in this case, but I have USB Debugging enabled.
I have all of the drivers update and USB debugging. Think I just got some shoddy cables.

I called Samsung and eventually after explaining what a micro USB 3.0 cable is and how it is supposed to work, and how it is not working, they finally gave me a place to send the cable and they will supposedly send me a replacement. I'm not holding my breath though. I think I would have had better luck addressing the envelope to "The Twilight Zone."

If your 3.0 charger charges fine but is not recognized when plugged into a port I'd check the the port drivers and make sure they are up to date. But first plug into all of your ports. It could be that not all of the ports on your lap/desk top are usb 3.0 friendly. And I've seen instances where if the device has not yet been recognized it will not pick up the device theough a usb 3.0 link. So maybe first get your note recognized by using a 2.0 connector then backdoor with the 3.0 and see what happens.
samsung test all of their cords before they leave manufacturing so getting a dud is very unlikely yet not impossible.
As for the aftermarket cords I normally stick to belkin. Best build quality for a fair price.

I have tried everything.
I plugged into 2.0 and the 3 options pop up to select a mode where 3.0 is grayed out. That menu closes when you unplug.
If you lock your phone while in this menu, you can change the port, unlock the phone and the menu is still there, but it will not allow me to select 3.0.
I have 2 3.0 ports on my laptop, 1 on the docking station, and 1 on my standalone.
None of them work with the aftermarket cable. I will take it as a loss as I really only need them for charging away from home.

That is indeed odd. Im not sure what to tell you. Hopefully someone will chime in and be of more assistance.
Try changing your network connections. Using usb3.0 puts on airplane mode. If u have wifi on or something it'll show greyed out. It might not be wifi but it's something similar. Saw the greyed out 3.0 the other day and changed a setting on my phone and it came back. Hope it helps.

I am having the same issue. I have 2 white usb 3.0 cables that I bought online from china via ebay. They were supposed to be USB 3.0 compatible and they look similar to the original stock cable.
When I use the stock cable w/ my usb3.0 port in rear of motherboard, the phone prompts me to enable USB 3.0 mode. When I use either generic cable, it will only function in USB 2.0 mode (I get no prompt for 3.0).
I am running DarthStalker Note 3 Version 6 and 3.4.0_Compulsion Kernel_7.0 on Tmobile version Note 3
I am willing to sacrifice (cut open) one of my generic cables if anyone thinks they can help diagnose the exact cause
I am having issues finding an extra USB 3.0 cable that performs to the level of the one that came with my phone. (My OEM cable works great)
I think the issue is that the 3rd party cables use cheap, thin wire. They can put a micro USB 3.0 tip on it... but the thin wires can't carry the bandwidth.
This is most plainly noticeable by downloading an app that shows the current flow while charging. Try downloading "Galaxy Charging Current *Lite*" and charge your phone through various combinations of
cable (USB2, USB3, OEM, 3rd party)
receptacle (1A, 2A, OEM, 3rd Party),
USB port (USB2, USB3, motherboard, adaptor card)
...etc. Even wireless charging, if you're equipped.
(It should also be noted that the phone will throttle the current flow as it gets closer to full. You'll get higher flow at 30% than 76% or 96%... so keep this in mind as you try different configurations.)
I've found that I got the best current flow (1800mA) using the Samsung USB3 cable, connected to a powered USB3 hub's charging port (no data, just power). This would charge our 3200 mAH battery from 0 - 100% in about 2 hours. When I swapped in a cheap Amazon cable (CableMatters brand)... the current flow dropped to about 800mA... or 4 hours. I emailed CableMatters, and they confirmed that it's a design issue, and that the wires are thin. They were pretty plain about admitting it... and then told me to return the cables to Amazon.
I'm posting all of this useful information not only to be helpful... but also to ask for help. Has anyone found a suitable replacement for the OEM cable? I'm looking for a charging cable... I'm looking for thicker-gauge wires capable of sustaining high current flow.
Any help here? Thanks!
If you are not getting 3.0 speeds then it's not a 3.0 cable. There are many fakes on ebay and amazon.
Only buy Amazon Basics or Samsung branded cables sold by Amazon OR Samsung.

Can you use an USB-OTG while charging. Can you find a charging contact point with VCHG, open your Fire tablet, find VCHG contact point and measure the VCHG contact point using the voltmeter.
The USB-OTG with microUSB port input can be used for Fire TV Stick.
I had one cable that did exactly this a few years ago and I for the life of me don't know what happened to it. now when it comes to OTG you should just have a separate piece of the cable splitting off that you would plug into the wall yeah and the rest of the wiring would make its way where it needs to. now here's where the tricky part comes in terms of whether a device supports charging through USB OTG. I know the fire tablets support this because you may not be using adb or OTG for any particular reason, and your tablet will charge whatever it is plugged into with that cable. If the OTG cable is built properly then theoretically it should charge your tablet as well. But really good and decent cables are hard to come by, that aren't really expensive. however when it comes to something like this I would stay closer to a name brand because you can get ripped off pretty easily even if you read the fine print and find out that it doesn't do what it says. There are no real big laws or regulations behind the cheap charger and wire industry, so you pretty much get what you pay for. It's just a matter of finding the right one.
