Hello.
I decided to try and make a DIY OTG usb cable for my atrix, followed one of the many guides on the web.
How ever, Nothing seem to happen when I plug something to the phone.
I tried keyboards, mice, pen tablets, thumb drives, but nothing happens.
Also when I connect the phone to my laptop with the same cable, nothing happens either. (From reading around I think that should be expected)
Using another cable the laptop recognize the phone and all is well so I didn't fry the port.
Something else that might be worth mentioning, I use a male micro usb to male regular usb and a converter to female at the end of that one.
I tried it with both latest CM7 nightly and Jokers 0.6.9.1 CM9, both on their stock kernels.
So am I forgetting / missing something or should I take apart the cable again and check what's wrong?
Edit:
Toke apart the cable, removed the connection between pin4 and pin5 and the cable worked as a normal cable again.
Can't think of a reason why this isn't working.
normal OTG cables don't work with atrix,
I have read somewhere that you need to power the otg cable with external power source, you can mod a powered usb hub for example
Thank you.
I don't have a powered hub, nor a regular hub...
So I'll try to make a usb y cable that will power the mouse/keyboard and see if that will work.
Edit:
That did the trick.
Made a Y cable that connects the data between the phone (with OTG cable between) and device and an extension that connects both to power only (currently from laptop usb).
At first it didn't work at all but after a few tries it started to charge the phone, allowed me to connect a DOK and a mouse.
However didn't want to work for a 250HDD or a pen tablet.
I ordered a usb hub and hopefully it will allow me to connect several devices at once.
Thanks again.
I've messed around with this quite a bit. Unfortunately, it seems Faux kernels don't work great with a variety of devices, but work fine for mouse/keyboard. Don't even work very well for USB flash drives and such. I don't even know where to go to report such issues.
This also means on Joker's CM9 it doesn't work great even if it should. Don't forget that CM9 port is still using a Froyo (!) kernel.
It's honestly not even worth building your own cable. You can get hubs that work for this for $5 such as this one:
http://www.dealextreme.com/p/cable-style-dual-power-1000ma-usb-2-0-4-port-hub-13526
Which is the one I currently have.
I'm currently using latest CM7 with the stock kernel and have no issues with USB flash drives.
It usually brings a notification of "preparing SD card" and mounts it under /mnt/usbdisk_1.0
I tried making 4 partitions on a flash drive, EXT2, EXT4 , FAT32 and NTFS .
Thought it only mounted one of them on /mnt/usbdisk_1.0 , it was easy to mount the others /dev/block/sda<1,2,3,4> onto /mnt/usbdisk_1.<1,2,3,4> thus having simultaneous access to all 4 partitions.
How ever the NTFS one only had read permissions since android and NTFS don't go together too well.
The hub you linked to is just a hub, I needed an OTG cable and ordered a 0.99$ usb hub that I will modify for power. so pretty much all set now.
As to reporting such issues, you could ask on the forums if other people have the same issues and how they get around them.
I got these:
http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774
I tried all sorts of devices, not least of which was a 360 controller. The kernels are very spotty at recognizing new devices being attached.
this is on CM9 of course
I haven't tried to replicate that on CM7 because, frankly, CM7 isn't supposed to support 360 controllers.
The hub I linked is very convenient. It already has a USB power lead as well as a lead for the OTG adapter.

can you give me direction how you did that.. how u provide power without usb hub??
I was writing some dodgy instructions from memory when I found this:

Hope it helps.
Haven't tried this yet but it looks pretty easy to implement:

You can use Stickmount for any JB ROM and use USB drives as well.

You would need a powered USB hub attached to the USB OTG in order to give enough power to most USB flash drives because the KF does not supply enough power by itself. Even USB mouse/keyboard would need to be powered externally.
Hello, I want to know how many USB-Devices you can use, assuming you use a normal USB-OTG cable and a cheap USB hub (without external power supply). How many devices can Android theoretically recognize? Is it possible to use a keyboard, mouse and USB stick/HDD? Would be cool if someone could try this....
Thanks in advance!

Android can recognize as many devices as there are USB hub ports, check out this video (I know it's for the Galaxy S3 but the idea is the same) specifically 2:50 seconds on using a USB hub with mouse, keyboard, and other accessories.

Thanks, but I think the hub used in the video has an external power supply. At 3:50 you can see the black round cable...

It should work the same with a non powered USB except that power will be drawn from the tablets battery power instead of an external power supply.

I tried to use multiple usb flash drives but they were not compatible with the aosp roms otg storage implementations. It recognized the first and after adding the second it didnt recognize it, but the first onewas still tdhere
I think in this case its simply not implemented
I will try flash drive + mouse/keyboard and give feedback when i have time

I tried for a couple of days to tweak the implementation in my kernel mod so that multiple usb drives could be mounted, i took pointers from my s3, but it seems samsung have further mods, probably to vold in their own brand devices and i couldnt for the life of me get it to recognise more than one device on the n10.

I think a powered hub is the way to go if you're using multiple devices as I'm sure there's a limit as to how much power the USB port can supply to your devices. You may find that several flash drives work fine together with a powered hub and I would try to get one with a 5v 2a adaptor if possible to give you flexibility to plug virtually anything in you wish simultaneously

Without a powered hub the deciding factor for how many devices you can use is going to be how much power each device draws... And that will vary from device to device.
I, personally, have had a keyboard, wireless mouse, flash drive and Xbox controller all connected at the same time with an unpowered hub.
Yeah, multiple flash drives and especially external USB spinners tend to draw a lot more power. Input devices (keyboards, mice, joypads) use very little power but a combination of several may be enough to give you intermittent operation and a few issues.
Usually when people start connecting keyboards and suchlike, they're going to be at a desk so should have access to a wall socket anyway; powered hubs tend to make multiple devices work better as it's a stable power supply available.

do you think the n10 provides less poser on its usb bus than a pc or laptop? i think its able to provide the same power as my pc and 3 usb sticks + wireless keyboard/mouse work perfectly with a non powered hub...
btw. i just tried the hub with 1 flash + mouse+ keyboard, works perfectly (aosp rom 2nd dec version i think)

I'm pretty certain that it does provide less; I have a 2.5" WD Passport HDD that is bus powered. My XOOM used to power it, my PC and laptops power it, but my Nexus 10 doesn't. The N10 certainly isn't pushing 500mA in host mode cause the drive can't even spin up on the power its receiving. It's a real shame cause I had hoped to power the HDD directly.
What I need now is a nice small powered hub that I can power from an emergency phone charger battery, like my Mili Power brick.

Is there anyway we can use camera on Nook Hd+. As Nook HD or HD+ doesnt have an inbuilt camera. SO is there any app through which we can possibly use our laptop camera or any other, connecting it to the Nook via Bluetooth or USB or Wifi, thus, able to access camera on Nook.
In short, if we can use PC webcam as a camera on Nook by connecting it over USB or any. This will leave a huge room open for accessing great applications demanding the camera.

First possible thing is Air Cam Live Video. But this maybe have many disadvantages for you.
Second i recommend look to this external link
For third i can say that Toshiba Folio 100 can use external USB webcam, but Folio have USB port too. I'm not familiar Nook 30 pin connector pinouts, but i hope there can be used for USB host too.
Yeah and hardware possibility is using some WiFi cam / spycam. Like this one on ebay (made just quick search for item, not for best price/deal). Disadvantage is that same time you can not connect your HD+ to another wifi network.
Edit: My mistake. This cam have two modes, infrastructure mode connecting it over local WiFi network or straight mode connecting HD/HD+ directly to camera.
Ip can will turn your phone into a wifi c connected comets which you can look at on some apps from play store,

I've been working on this issue for about 2 weeks. One important question: Do you want a cam for security/surveillance/monitoring or for video conferencing/calls/Skype? The options for the former are much broader, but remember most security cams do not have voice capability. I'm in the video call camp.
If money is no object, I would think an IP cam with mic could do the trick, or possibly B/T, but since I'm looking for a cheaper solution and to have fun with this challenge, I'm going the USB route. For this purpose you need to make the HD plus become a USB Host just like your PC or Laptop. Not a problem, theoretically, since that capability is built into the Android OS on your device, but getting it to talk with a USB device, such as a camera, is another matter. Connecting it is the second challenge; there is no USB OTG cable (the "special" cable for USB Hosts) for the Nook. It would have a female USB connector on one end and Nook's (f**k**g) proprietary 30 pin male connector on the other, through which you'd connect your USB device. I've come up with a hardware workaround, but I'm waiting for a special connector coming on a slow boat from China. A side hardware problem is the lack of power coming into the USB Host (the Nook) and the USB Slave (the Cam), but utilizing a powered USB hub could solve it.
So, if the hardware problem is overcome, will it work? Video cam APKs are aplenty on Google Play, but I don't yet know if they will play (pun intended) well with the Nook's USB host adaptor set-up. I'll let you know. Total costs with a new cam will be less than $20; if you already have a USB cam (with built in mic), it'll be about $5. Nice.
Flamers put away your blow torches. If I really wanted or needed a cam I wouldn't have bought the Nook HD+. I know that. This is for cheap thrills.

First, you must use a USB OTG cable with a special female USB connector (it'll look conventional) on one end which will identify the device as a USB Host. Unfortunately, most connectors on the other end are male micro usbs, or 30 pin Apple connectors, not the Nook 30-pin. I bought one with the male micro USB plug. Now I'll need a female micro USB to female USB adaptor to connect it to the Nook.. That's the special adaptor coming from China (http://www.ebay.com/itm/271094375029?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649).
The configuration of the set-up is this:
Plug in to a/c outlet a powered USB hub (2.0)
Connect the primary cable of the hub (i.e., the one that would go into a PC/laptop) to the hub and to the USB female end of OTG cable
Plug the OTG micro male to the like-female end of the special adaptor
Plug USB cable from the Nook into the other end of the special adaptor then into the Nook
Plug USB device you want to use with the Nook into one of the ports of the USB hub.
If all goes well the Nook should identify the device, but you'll need drivers and maybe an apk to use it. Whether the drivers load automatically or not remains to be seen.
If I get to that point I'll let you know what happens from there...

It would be surprising if this works. USB OTG cables have 5 pins; they distinguish the host side from the peripheral side by shorting the fifth pin to either ground or +5V. But the Nook's USB cable ends in a 4-pin connector. There's no way to tell it to act as a host.
On the bright side, the Nook's kernel definitely contains support for host-side USB. It has drivers for mass-storage, HID (mouse, keryboard, etc.), serial, and video devices. To use these facilities, though, it would be necessary to wire up your own 30-pin connector. As far as I know, B&N has not made the pin-outs public.

I was operating on the premise that only the female end of the OTG cable required the 4-to-5 jumper. Alas, the male end also requires the same configuration. I could tackle modding the female USB end, but the 30-pin connector is another story. Thanks again to B&N for making a proprietary cable. Another smart move on its part -- limiting the inherent functionality of this device. It hasn't made an OTG cable and probably never will since it is cutting back on its Nook investment. They blew it, but that's another story...
Appreciate your comments above.
I attach us electronic mechanic to investigate my opened HD+. Maybe we can find some interesting pins.
Only one i dont want to do, this is cutting off this 30 pin plug at cable side. Its hard and over prized to buy new cable to my destination.

No hardware fix, but follow this link to use a software hack which requires CM10.1 for your HD+: http://forum.xda-developers.com/showthread.php?t=2307585 That should work.
Doesn't work because we need a camera app. Any ideas for that?
Ok guys. I've been messing around for some long time using 4.3 rom and my 2tb passport but with no luck reading (or writing from it). I was under impression that phone has to be rooted for reading only NTFS format but....this is fairy tales if you ask me. Recently I upgraded to latest kitekat available and rooted but still no access to my drive. I tried 3 usb sticks (8,16,64) with no problem using FAT format.
I used paragon, stickmount but nothing helped me to work this out. I'm also having second doubt would I have more luck with exFAT format?
Anyone had similar problems connecting 2tb drive to their Note 3? And disk is spinning I'm positive it has enough usb power.
The phone can only support up to 1tb due to power restriction.
The only way that i managed to get a WD 2Tb drive to work with my phone/tablet was to use a powerbank. The phone doesn't give enough power out to start the drive up.
You need :
- 1 powerbank (the bigger the better, as it will also charge your phone/tablet)
- 1 USB Hub + OTG cable (or an USB Hub that can be used as OTG with the phone)
- 1 male-to-male cable
- the phone
- the external HDD
Connect to the USB hub the HDD using the cable suplied with it, connect using the male-to-male cable the powerbank to the USB hub and then connect the USB hub to the phone using the OTG cable (or if you have an OTG cable with USB hub integrated then it's even better).
Now, the powerbank will give power to all devices connected to the USB hub (the HDD and the phone), so it should work OK.
After that you will need to solve the NTFS reading/writing, for that you should be able to use the app you already mentioned.
P.S. when i was playing on the Tab2 with the above configuration, I also had to put an usb stick in the USB hub. For some reason the tablet didn't detect the HDD on the hub unless there was an USB stick too (never understood why). I don't remember having the same problem with the Note3, but i didn't test extensively so your mileage may vary.
Edit : an example of OTG adapter with integrated USB hub for Note 3 : http://www.ebay.com/itm/Micro-USB3-...-TF-Samsung-Galaxy-Note-3-N9000-/171300593212
Thanks for reply verszipo I was looking at this cable, hoping this could power up the drive while phone continues to operate itself without additional power. So Is it possible to have power supplied directly over wall plug instead of power bank?
This USB hub seams like nice idea.
Theoretically connecting like you suggested should work even if I leave disk in NTFS format using tools I mentioned before?

If external hdd is larger than 1 TB,
Use usb "Y" cable to add external power source to connection.
Hey!
I use 1.5TB HDD with mu N3 and it is NTFS...
Why cant you use USB hub with external power supply (try to find out if it is 1A or 2A? bigger = better), and at phone install total commander with plugin USB plugin for Total Commander (no root requided!!)...
I use a 2tb wd passport. No need for external power source. I use paragon to read and write to ntfs partition. My drive gets detected within a few seconds but takes several minutes to mount the drive. Maybe you just need to wait. I know my drive is mounted when the My Files app launches by itself and shows the drive contents.
I received my Y cable hoping extra juice could solve my problems but I have no luck at all. No matter what I use I can't make my drive read. I don't have any options to choose.
Maybe I should format my drive using different allocation size unit, I never formated it and it's not 4 months old. Maybe my phone has some crappy cache leftovers so I should use cleaner? Hell I don't know what to do anymore. Usb sticks are working fine all the way.
Ok update on topic. I mange to make it work. I formated to NTFS with default allocation size, nothing special. Using paragon + total commander plugin + total commander. Works fine now WITHOUT additional power. Only downside is that mobile battery drains way too fast when you connect storage on it. It does not matter if I plug in additional supply to drive or not, draining is the same. Anyone noticed this and any workaround for this.
Thank you guys for suggestions.
I mounted my CN memory usb3.0 3tb drive with paragon in my rooted sm n9005
It mounted fine to a folder in my int SD, and i copied ober 20gb of data
