Hey! So i managed my S2 to work with an OTG adapter. Now it recognizes Flash drives, USB mouse and keyboard as well. My problem is though, that i'd want to use both the mouse and the keyboard simultaneously, and later on my tablet as well.
I've got a USB hub which was pretty cheap i guess,
ht tp://itmedia.sk/item-images/other-usb_omega_hub4portSTARpowercapable/it6818_2.jpeg?nc=032
When i connect it to the OTG adapter it lights up, and if there's a flash drive attached to it when i plug it in, the phone recognizes the flashdrive without problem. As soon as i plug in a second flash drive, the light goes off from the HUB and both of the sticks get unrecognized. Also, the mouse nor the keyboard works through the HUB somehow..
I need to buy a specific hub with OTG support or a power hub perhaps? Could anyone help in this? I looked over google and stuff but people seemed to say different stuff at almost every site.. Thanks!!
My Galaxy S has stock 4.0.3 rom with the Syjah S2 4.1.4 Kernel

Oh well that's quite interesting. Then you're saying this piece of video could be fake perhaps?
Since i can post links yet, search for this on youtube: USB HUB Support On GALAXY S2
Check the very first video.
I'm convinced that the every phone can handle only one device connected at the same time.

Well, it surely doesn't seem that way, that's why i was asking, since it's possible.
Weird.... i got sgs2 and 4-port usb hub and when i connect 2 pendrives to hub and hub to phone everything works good (i see UsbDriveA and UsbDriveB). If your hub have dc input you can try connecting power supply to this hub. Maybe this hub isn't compatibile with your phone.
Is there a way to get midi input recognized on our phones? On my pc I use the rock band 3 keytar connected via a midi to usb adapter and I can do midi playback.
Is there a way to do this on our phones via an otg cable?
EDIT: got it done! check my post below.

it works beautifully and way easier than I expected.
connected my otg cable and the phone said usb connector connected (since when is this a thing!?), plugged in the midi-usb adapter to the otg cable and right away it prompted me to open with the software I linked above and another midi software I had installed.
and bam, it was working. I messed around a bit to find the better settings for my keytar, but this thing works. over Bluetooth and with the headphone plug. there's a little bit of lag over Bluetooth but for my uses I wanted it straight to the speaker so i'm using the stereo cable. now I don't need a pc to get sound out of the keytar.
mark this as one more day i'm amazed at what my phone can do.
by the way, it functions as a synth using the software I mentioned above, so I can play harpsichord, organ, piano, etc. and the sound keeps on playing even with the screen off.
happy camper = me.

Looks like you had some luck... Wondering if you can help me?
I am trying to make my Android, Huawei p20 Pro, accept a MIDI signal via USB too.
I have an OTG adapter, and have tested 2 OTG adapters and 2 cords.
All work into my PC (even via an USB type-C to standard USB adaptor )
The issue seems to be that I cannot select the USB in type to be MIDI.
I have also experienced that on another Samsung Galaxy S10
I have tried opening developer settings and changing the setting "Disable USB Audio Routing" ON as per https://help.joytunes.com/en/articles/2636638-troubleshoot-midi-on-your-android-device
I have tried using it with 3 apps that accept MIDI.
Simple Piano by Joy Tunes, FlowKey and USB MIDI Monitor
Any ideas?

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

I have been trying to connect a bluetooth headset to a Class 1 bluetooth USB dongle (connected to my Nexus 7). I wanted to use the Class 1 USB bluetooth instead of the built-in bluetooth for the range. In short, using the Nexus as an bluetooth mp3 player which I don't need to have relatively close all the time.
I followed this forum's rooting guide and successfully unlocked/rooted the Nexus. I plugged the USB bluetooth in via an OTG cable and the light comes on (good start). Using a terminal, dmesg has the USB's details so I'm assuming the kernel has the appropriate module installed at the time. I used the USB Host Controller app and was able to see the device listed.
This is as far as I've been able to go. I don't have hcitools, hciconfig or hiid available to take this further. Another forum provided these 3 for installation however, when I tried running them, an error came up saying libbluetooth.so could not be found.
I'm unaware of an app like Linux's Blueman which could let me choose between bluetooth devices (the USB and internal) so I'll probably need to do this via command line.
Can anyone help me out with this?
