Hi guys,
My galaxy nexus screen has been cracked and it does not respond in 75% of the screen.
I bought a MHL to HDMI convertor on amazon and luckily got the phone UI to show up on my TV
Now since the touchscreen won't work , I need to connect a keyboard or mouse via USB OTG and use it for navigation.
Problem is the Galaxy Nexus has only a single microUSB/MHL port combined into one.
I have no idea how to split the output from the phone to connect to a USB OTG cable and MHL to HDMI adapter simultaneously !
Any help will be appreciated,
The phone is not rooted AFAIK , but may be I'm not sure. It was running Android 4.1 JellyBean when I dropped it on the floor
The phone does show up on my Windows PC and I have copied the photos off it. But I still want to copy contacts and SMS messages.
You tried just using something like Android Screencast from the PC (USB debugging is needed)
Also, some MHL adapters have a USB port in them, for power. Have you tried getting a crude micro USB splitter? Like this one? http://www.replacebase.co.uk/micro-usb-female-to-2-x-micro-usb-male-splitter-2392-p.asp#.URk59JGYOBs
Not guaranteed that would work though. Also, a quick google of what you want brings up some others with the same issue, have you tried to see if any of them have succeeded?

Good news
I had a spare galaxy nexus in the office and I gently took the screws of both the devices , and just swapped the displays so that I could quickly turn on usb debugging , backup essential stuff and also turn on bluetooth.
Thanks to some assembly videos on youtube ! will share some pics soon
Hi all,
I've done a search regarding this and cannot find any relevant posts. My Ouya micro usb port has physically broken and i'm trying to recover my ouya again. I can boot it to recovery screen via usb keyboard but have no way of physically connecting to it since my micro usb port is broken. Would there be any way of connecting a Nexus 7 via OTG cable to the other standard usb port? Or can anyone suggest another method of connecting?
Wireless is out, cannot flash from usb pen drive have I any options left?
Could you somehow do adb over a wired network?

I'm trying to connect the unifying receiver to my Nexus 7 (2013) with an OTG cable, but it doesn't work.
USB diagnostics app by Chainfire says the kernel detects it, but the Android API doesn't (not sure what that is). All other USB devices I have tried seem to be working.
I think I read of other people having the same problem. I was wondering if this was a problem with the 2013 Nexus 7 in general. If so, is there a fix? or will there be one?
Also, I was playing with my tablet and OTG cable; I was wondering if anyone else has USB devices "sleeping" when the tablet is put to sleep.
I noticed when I plug the cable in the tablet while it is awake, and then plug in a USB device, the USB device will work fine until I put the tablet to sleep. After I put the tablet to sleep, the USB device would power off, and after waking the tablet back up, the device would remain off and unresponsive.
The workaround I found was to plug in the cable while the tablet was asleep, and then waking up the tablet before plugging in USB device. I would then be able to put the tablet to sleep with the USB device remaining powered (while it's asleep and) when it's awakened.
Sorry if this was confusing.
Thanks!
I've got a working OTG fix that does not require root after much messing about!
Go to settings and disable security lock screen then select English US as the language.
Insert OTG cable and start Nexus Media Importer.
Reboot.
Nexus Media Importer should now pop up as usual and OTG should now be working.
Change language back but do not reboot as you will have to repeat these steps.
Same problem..
I have tried nexus media importer or custom kernel, ETC.. however, the problem is occurred again.
Everytime, kernel has error like..
Code:
logitech-djreceiver 0003:046D:C52B.0018 : claimed by neither input, hiddev nor hidraw
logitech-djreceiver 0003:046D:C52B.0018 : logi_dj_probe:hid_hw_start returned error
Is there anyone uses unifying on Nexus 7 2013? :crying:
Same issue with the receiver
My Unifying receiver works on my SGS 3, but it doesn't seem to work with my nexus 7 :'(

Any News in this area? I Bought my Nexus 7 to use it during class (as a studytool ofc) . But without having my external keyboard it isn't of much use
I've been having trouble getting my Logitech K750 keyboard to work on the nexus 7 (stock ROM, only rooted). Does anyone know if the Logitech Unifying Receiver is supported on this product? It works perfectly fine on my Galaxy Note N7000 running CM10.2
I can get other USB devices to work on the Nexus using the same OTG cable, for example Logitech MX Revolution wireless mouse, Xbox 360 controller and USB flash drives.
Same problem
I have the same issue with a stock/non-rooted Nexus 7 (2013) and my Logitech unifying receiver. Sadly all I can really say is what did and didn't work.
Does work:
OTG adapter from monoprice.com
Trendnet Powered USB 2.0 Hub (TU2-700)
Microsoft Wireless Mouse 5000
Every USB flash drive I've tried has worked via the 'Nexus Media Importer' app (FAT/FAT32 devices). Even multiple plugged-in flash drives connected simultaneously via the USB hub works just fine.
Custom built USB 2.0 External Hard Drive (using a Nexstar enclosure and Western Digital 320GB hard drive; powered off USB hub)
Apple iPhone 4s (iOS 7) - The tablet called the phone a MTP device and viewed the media (pics) through the built-in Gallery app importer
Does NOT work:
Logitech unifying receivers - Specifically, I tried with the K360, K400 and K750 keyboards and a M510 mouse
USB 2.0 10/100 Ethernet Adapter from monoprice.com (no apparent model # but it's their PID#: 9468)
USB 2.0 Logitech C910 Webcam
USB Logitech Headset G330 ...I was just curious
So far compatibility seems arbitrary. I would have thought the Nexus 7 (2013) would have better compatibility with Logitech, a maker of Google TV's, versus Microsoft or even Apple but that has not been the case. If this is a bug, it's a big one considering the popularity of Logitech devices. Sadly, I personally don't even have a keyboard that will work.
Any more details about this problem? Surely this must be a driver issue, since I don't see any other reason why the unifying receiver would refuse to work on the new Nexus 7. As stated above by others, it works perfectly fine on other devices, including the stock rom running TF101 transformer tablet.
I'm running CM nightlies on my Nexus 7 and was really surprised to see that it doesn't work with my unifying kb & mouse

Just tested with a different USB tester app - the receiver is obviously recognised. The OS can see it, and gets the device/vendor ID, and the device name... but no mouse cursor

Tested it with an older Logitech mouse that I have (doesn't use Unifying receiver), and that worked just fine..

But I need the new unifying one to work, mostly for the keyboard.
This issue is discussed here: http://forum.xda-developers.com/showthread.php?t=2233849
I'm also having trouble with this. My K400, which would be awesome for tablets, isn't able to work, for it uses a Logitech unifying receiver. It seems it's a simple fix within the kernel. I've tried flashing many different kernels for this device, yet none have added support for it. The device works well on my Galaxy S4, if that means anything.
We'll need to get ahold of one of the developers and hope they're willing to add in the necessary stuff to their kernel if we want to fix this.
Could it be that a current Nexus 7 dev has to integrate some of the patches listed in some of the roms posted here: http://forum.xda-developers.com/showthread.php?t=2233849 ?

The Logitech Wireless Touch Keyboard K400r works with its unifying receiver and OTG cable plugged into the original Nexus 7:
Android version 4.3
Build number JWR66Y
Kernel version 3.1.10-g1e8b3d8
But the above set up does not work with the 2013 version of the Nexus 7:
Android version 4.3
Build number JSS15R
Kernel version 3.4.0-g9e52a21
Bump
Solution Anyone?
Can't believe that none of the N7 developers are using a logitech device! !
I got a K400. Works fine with my nexus 5. Not with the nexus 7 2013
need an updated or custom kernel
It looks like we'll need an updated kernel, which has some extra CONFIG switches activated, per these threads:
http://forum.xda-developers.com/showthread.php?t=2233849#2
Has anyone had success with a custom kernel or rom that includes the kernel drivers for the Logitech unifying receiver?
It would be nice to have a minimally changed kernel that included support just for these new drivers:

Updates?
Hey all
Was just trying out the Unifying Receiver today and was surprised and disappointed that it didn't work at all.
Has anyone managed to get it working since the last post?
P
no
After my last post, I contacted Google support. They said that they could not help, and Logitech would have to fix it. I tried to talk technical about kernel config switches, and I begged to talk to someone who understood what I was saying, but I basically was told they did not have resources to troubleshoot every possible accessory.
I contacted Logitech, and they said that Google was right. They claimed responsibility and stated they did not support Nexus 7 (2013). It would not work.
Bottom line: This accessory will only ever work in a custom ROM, if it works then.
If anyone has any luck with this accessory on a custom ROM or in any other setup, please let us know.
Earlier posts say it is recognized by the OS, but not Android API.
Then, all it needs should be the files to tell Android it is a mouse and keyboard, right? Seems like the only issueis our device didn't have it in its device list.
What file to mod, what line(s) to mod?
Has anyone found a fix for this? I just bought a Google Nexus 7 2013 - 32GB and am trying to use the unifying receiver with an OTG cable (Logitech devices are the K800 keyboard and Experience MX mouse). The unifying receiver works fine on my galaxy S5 but no luck on my nexus 7. I am currently unrooted running stock lollipop 5.0.2. I am prepared to unlock bootloader, root, and install custom kernel if necessary.
Any info to get the Logitech unifying receiver working on my Nexus 7 would be greatly appreciated.
Hi all.
Had this unit for about two weeks. I've read various blogs / posts regarding OTG and I bought two cables from Monoprice. When I tried to connect either the PS3 controller or USB flash drive, the device doesn't recognize it.
I downloaded USB Host Controller and it has a message "S3C USB Host driver NOT found". A lot of sites show connecting a PS3 controller is fairly easy but I can't get this to work.
I'm on 4.3, not rooted. I'm not sure what I'm supposed to do. Do I have to root the device to get this to work?
Note no issues with USB charging. When I plug in to a laptop it does show up as a "media device". When I plug in the OTG cable I have no notification message.
I also have a S4, and when I plug in the same OTG cable, I can see a message 'USB connector connected" on notification. But I can't see the same message when i plug in my Nexus 7 2nd Gen.
Is this a common problem? Thanks in advance.
I am use star print and connect to a HP fax combo works fine. Need check USB debug in Dev option s. Noon rooted . also use otg explorer to play movie s I f a San disk 6Gb USB thumb. Both apps are $2.99 but. The lite version work great for testing
