I got board so I grabbed a USB OTG cable I had from my Atrix and it worked fine, I did notice that it doesn't seem to charge over the cable and I only managed to get a keyboard working. When I root I'll have to see if I can't manually mount a drive, I used to have to do this with the atrix so I wouldn't be surprised.

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.

I bought a 32gb SanDisk Cruzer Fit to store my music library on, and it worked initially with USBOTG and stickmount. However, it no longer works with Nexus 7, all other memory sticks are fine, and the SanDisk works on my PC, but not the Nexus 7. Anyway, I plugged it into a USB hub and it works again, but only through the USB hub. Anyone else noticed this kind of behavior? I'm guessing it's related to power draw, as the hub is mains powered, but I'm surprised it can't cope with a flash drive. I'm now wondering whether to buy another device, or whether the same thing will happen.
I had the something similar and a reboot fixed the issue for me. I tried plugging in my 250GB WD Passport but I guess there wasn't enough power for the external drive because it kinda just sat and clicked. I then tried plugging in my 16GB thumb drive that I know worked the day before but now matter what I did, I could not get it to mount through StickMount. I rebooted the Nexus7 and I was then able to use my thumb drive again. Not exactly the same but try a reboot if you haven't already.
I also have that problem with my Buffalo USB hard drive, where it sits and clicks, it's OK via the hub, but not direct. A reboot doesn't make any difference. I'm wondering if it's my USBOTG cable, as that's the only variable, I have read that others have got the SanDisk 32gb to work with the Nexus 7. I'll try another cable...
Got my new USBOTG cable, and the Sandisk 32gb now works. My external HDD still doesn't work (unless plugged into hub), but that's not too surprising. The new cable is this:-
Afunta(tm) USB 2.0 A Female to Micro B Male Adapter Cable (search on amazon.co.uk)
The old one works with most of my USB sticks, but is maybe not as solid in terms of build quality, as the new one is much tighter. The old cable is this:-

Hello Eveyone
A friend gave an OTG cable so I could try it on my acer A500 (stock ICS), but when I connected the OTG cable to the micro usb port and then plugged an usb pen drive nothing happened, also tried with a logitech gamepad and nothing as well.
I would like to know if there is a way for my Iconia to use/recognize the OTG cable (I know it has a full size usb port and it is working ok, but I want to be able to connect more than just one device).
So I bought one of those cheap (sub $1) OTG adapters from Amazon, and up until today it worked. I was able to import photos from my digital camera and use a USB mouse. Today I can't get it to work at all. Not the mouse, not the camera, not anything else.
Regular USB (charging and PTP mode, I would have tested MTP as well, but it's not compatable with my laptop) works fine. I'm able to transfer files to and from the tablet, and it charges fine.
Is something wrong with the OTG cable or my tablet? Will I have to buy a new OTG cable to test?
If its only <$1 just get another one or two! Sounds like a cable problem if everything else is working
Christmas is coming, I see the shadows of Ebeneezer Scrooge !!
Are you using stick mount to load the OTG onto the N10? If so thats probably why. When i first installed my stickmount it worked but wouldn't see any of the files on the USB drive. Now after i've unlocked and rooted the device it won't even show the usb drive attached. I switched to Nexus media importer and it works fine, but i believe stickmount is having issues with 4.2.
However if the OTG cables did cost you less than a buck replacing them may be the solution too.
I can connect my V20 to a Windows PC via USB cable, and transfer files back and forth. I had to pick something on a menu the first time I plugged in the phone.
However, if I plug a USB stick directly into the V20, it does not recognize it, or respond at all. My friend plugs the same USB stick into his V10 and an app pops up and shows the folders.
I'm using a micro-USB to USB-C adapter on the stick to plug into the V20. I know the adapter works, because I tested it when connecting to the PC.
I have searched settings for "USB" and it only comes up with USB tethering.
This is an AT&T stock phone, using the stock launcher. No root or anything.
Any idea how to get the USB recognized on the V20? Thanks.
it might be that the USB host function doesn't work with those adapters. have you tried plugging in a USBC to USB adapter and plugging a flash drive into that?

I've tried the same thing without success. My note 3 & 4 worked fine. I also had a Note 7 and Nexus 6P and it didn't work with those either.
has there been any advancement on this issue?
Did anyone find the answer to this? My V20 used to boot up a USB stick but just stopped working one day.
