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:
http://forum.xda-developers.com/showthread.php?t=1828032
Hope it helps.
so picture it you're using the tablet for video or music running from a memory stick via OTG and you want to be able to power/charge the device at the same time without having to remove the pen drive is there any way of achieving this?
some kind of pass through device perhaps or a usb hub of sorts?
How to power with usb-otg
I can't confirm whether this will work for the Nexus 7 but it has worked on my Triumph and Photon 4G. Go to meritline.com and look for a Pisen® Multi Purpose USB Hub, White (sorry can't post links yet.) Plug your otg into the white port and the red into any available usb power supply (be it a laptop or charger) you may want to have an extension available depending on your set-up. For me this has provided power to keep device charged as well as interface thumb drives, card readers, etc, has even powered a bus-powered external hdd with no problems.
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?
Greetings all-
I am an IT professional and was thinking how handy it would be if I could just plug my phone into our wired ethernet network to test if a port, cable, switch, etc is working properly.
Goal: To plug my G2 into an ethernet cable and use one of the IP info apps (or packet sniffer apps) to do some network troubleshooting. Basically, I would want to know if DHCP is working on a port and what IP info the phone is getting.
I know they make ethernet testers that can be plugged into a wire for testing/troubleshooting purposes but these are expensive and can't do what an sniffer app can. Plus I always have my phone and can easily carry a few extra cables with me to make this happen.
Experiment: I bought thingy one and thingy two.
I plugged both of these into my phone and then connected the ethernet cable. I saw the link light come on, so I know there is at least some connectivity. However, I am not able to get any data to pass through to the phone. I set the phone to airplane mode (so it won't use any wireless networks) and try to access the internet and I get nothing. The G2 doesn't know how to use the ethernet connection.
Does anyone know how to make this work????
Thanks for any help you can provide!!

Nope, but thinking it through should be possible. In short you just have to configure Android/Linux to use the 802.11 adapter on the USB port. Would be interested to know what the log files have when you plugged in to the G2. Suspect
1) You will need to be rooted
2) Would try get the LAN adapter working on a Linux desktop first then go back to the G2. If there are Win, Mac & Linux drivers should be possible why Android is 'limited' to ASIX AX88772 chipset needs to be understood though.
Good luck
You will have to write specific drivers for it. It isn't just convincing the kernel that your microusb port is your 802.11 port, because the technology is different. Ethernet doesn't have to worry about maintaining a connection over the air, but it does have to remember which wire is used for what. So it would need an actual driver written for it.
