Sorry if i wrong for creating this thread,:fingers-crossed:
i just wondering , is there anyone can implement USB Host Driver for OTG function into our sgw kernel ?
i read it from here , hardware limitation is not a problem since we can using external power to supply our USB Devices.., i had one hand made Y OTG Cable that function normally in my friend mobile SGS2 & NeoV but nothing happends when i pluggin into my SGW, so the problem looks like from the kernel / software that not enabled for this function
just wondering

When i connect Desire to my PC, my USB TV Tunner stop work, i try'd to switch both devices in diff usb slots no diff. There was no problem with HTC Touch Pro. weeeird.
Does this have any solution at all ?
Sounds like your PC doesn't have enough power to power up both devices.
Good point there, just tested it, turned of my external USB HDD but still no diff. I don't get it, well everything new brings you new trouble with all the goodies ofc
It stops my net working, I have to reboot once I have disconnected usb.
Today i bought a USB OTG cable.i am running full stock 4.0.4 . when i plug the USB OTG cable to my phone & then to my Mouse it does not work.all i see is my mouse led lights up for about 5 seconds then turns off.the same thing happens with my keyboard also.
My question is -
--> Do i have to make some settings changes ?
--> Install some kind of application ?
--> or is there something wrong with my OTG cable & i need to replace it ?
dude first install the usb modules on your phone...
go here http://forum.xda-developers.com/showthread.php?t=1588979
I installed the Modules but still nothing happens.it's the same.
Update : when i insert the USB cable of mouse half way then the mouse's LED lights up & stays but nothing happens the the mouse does not work.no cursor appears.
may b there is a prob with my OTG cable . i am thinking of changing it tomorrow.
thanks for the support.
did u install that app? did u install modules for stock kernel? did u try connecting pen drive?
yes i did all of those things . when i plug in the pen drive it's led lights up but in cell phone i don't get any indication of any new device found. . .
Stock ROM doesn't need any modules. I use Nokia N8's OTG cable, and it works fine. The mouse cursor comes immediately after connecting the mouse. The cable may be a faulty one or, it is for Samsung phones only, and since Samsung uses different wiring, so it is not working properly I guess..
Sent from my LT15i using xda app-developers app
Yes i got the problem Fixed .turns out it was a faulty Cable.got it replaced & now its working fine..
Thanks for all your support ...
Hello,
Would like to thanks in advanced for anyone who replies with any relevant concrete info.
Since i got my tp-24g01 wireless touchpad keyboard in Japan back in 2009ish, i love it. its a 2.4ghz wireless keyboard kick ass keyboard. anyway it works flawlessly on otg with htc m8, pc, ps4 but not on n7.
I have nexus 7 flo 2013 wifi 16gb with cm12 of may 30 2015 with elementalx kernel for cm.
i cant really blame cm12 rom for being worse than stock in this case, let me explain,
out of the box stock rom and then even updating it from android v5 to 5.1 the keyboard would be recognized by the device but after a few seconds it would start to stutter and eventually i would have to plug in and back every FEW seconds. --- why me right --- i guess people like to use bluetooth and i could buy a bluetooth keyboard, however my hands are totally used to the layout and width of this keyboard, plus i like how it looks.
---- thus the reason why i changed to cm12 with elementalx kernel ---
it was worse, the rom would would not even recognize the keyboard. i pretty much downloaded all the usb otg helpers on play store, somehow i end up searching for s3c usb host drivers for android, and with that i was finally able to use the keyboard, it works better, but still it timesout.
ive read on xda that nexus sometimes requires extra electricy current for some things to work. this is where my question comes in..
is there way to stablize, regulat by force the output voltage so that it doesnt time out.
im an afficiando for all this stuff so i cant really be 100% certain,
however, i do believe its some kind fo voltage issue because ive used my m8 with the keyboard i n the same spots and it doesnt time out. when i download something it drops hard.
anyone know of solution for this
is it possible to force regulate or increase the power the nexus give to the otg?
any rom or kernel that has this fixed?
i would even appreciate key terms to search because i have burned out of ideas
Update
Been reading a lot
This device is really bad for hardware
Without using stickmount and otg power lock
Transfer speed to otg USB was 1.3mb/s and times out after 15 minutes ::: hate this device :::
With I get 4mb/s and the file transfered before 15 minutes so I don't know of would have timed out
Not to mention I had to boot it up connected to the otg
Makes Total sense that my wireless keyboard timed out
I'm still hoping for some software solution to this but I know it that will most be unlikely.
Have big expectations for the HTC version as I love that company
Final solution order y otg cable or powered hub and Bluetooth keyboard for when I travel.
MasalaMa
its me again
have some news.
Although it seems tht the nexus otg does not have the same type of support as my htc m8
the initial root cause of my problem
when i flashed elementalx kernel i selected otg usb charge, duh, it was a no brainer why the otg wouldnt mount my keyboard
however the sc3 usb host anroid drivers did help to fix this unnecessary problem
after having freshly flashed cm12 again the keyboard is recoginzed but the same problem persists as it did with stock rom. problem still there after trying to juice it up with the elementalx kernel by boosting cpu clocking and perhaps will start testing other kernels for other i/o scheduling and governors
any tips? recomendations?
i also installed OTG power lock which to some extent may have helped but im still getting the same issues. it seems that with this app helps a bit, however still insignificant.
might have to ge really technical
Hi guys i have a problem.
So i have played with an mhl cable.......anyway my usb port on my device is not working anymore so any repair or anything?
And i forgot to say that charging works normal also tried otg cable and it does not work. maybe a new motherboard?
If charging mode works normally, so maybe You have another problem... Hmm You cant connect Your phone to PC or what? Maybe there is a driver problem?
on CM 12.1 and I can get SOME flashdrive to work otg, SOME of the time.
I tried stickmount and ex kernel, but it's the same (worst on ex kernel, can't even detect otg)
I tried using a powered usb hub to see if that was the issue (for some reason, the microusb port isn't giving power to the drive. is this normal?)
after several more testing, seems like there are 2 issues that is causing otg not to work all the time.
1. Power. Doesn't seem to be able to provide enough power for self powered usb devices (ie. flash drive, dac, etc..) or enough to maintain connection.
2. Microusb port. might be one of the reason why devices aren't getting enough power and/or not being detected.
I really think it's a power issue cause everything seems to run fine if I connect it to an external powered usb hub. I tried the same setup (flash drive and dac to an usb hub, no power) with my 1st gen Nexus 7 and it had zero issues.
so is there a way to raise or maintain 5v OUTPUT out the microusb port so it doesn't randomly disconnect otg devices?
I've been able to power A pretty heavy duty usb audio interface. I think I may have had that issue A couple times, but it was never A big deal for me.
I don't remember having the problem after enabling "OTG+Charging" in Elemental X kernels' aroma installer. Did you use that?
Also possibly (not likely) A Cyanogenmod issue. I haven't used that on the nexus 7 in A while though.
Wierd that flash drives don't stay on. Does it do that frequently? I've looked into "overvolting" the usb port A long time ago, it seemed to need A kernel change
