Hi
any chance that there will be a kernel for the G-Pad that supports
charging the pad in OTG mode?
Timur managed to add this feature to the Nexus 7 kernel...

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
Has anyone here got the USB OTG cable working with an external Hardrive? is yes can you say what kind of Drive... i got a 1tera i think is ADATA
Most external hard drives draw to much power for a external disk i think. I've used several thumb drives, but not hard drives. An external ssd would be you're best bet as there aren't power sucking mechanical parts in them.

I did on my note 2 prior to selinux since then (kitkat+) (Haven't on my note 3 because I frequently use screen mirroring which won't work with modded kernel) if you don't use screen mirroring then you'll need a kernel that has selinux set to permissive mode (Jovvy has a stock kernel modified with permissive mode posted in original development thread) to be able to use 3rd party ntfs apps to be able to view files, unless your hdd is fat32 (which will read as long as adequate power is supplied) NTFS requires permissive mode.
**I used a 1 tb Seagate that uses wall-power
I also have a Western Digital "My Passport Ultra" that is usb powered that powers up fine when connected to my note 3 but since my selinux is enforced I can't read the files, but it would work with a modified kernel no problem

i'm using the s5port... with leankernel and sidesync for screen mirroring doesnt work.. it always shows me a black screen on the computer.

Yup, screen mirroring will only work with stock kernel.
I'm using leanKernel and sidesync works fine. Stock rom, though.

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
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
Hi!
I am planning to repurpose my Galaxy Nexus (Maguro) running CM13 as a media player/rear view camera viewer for my car.
I want to use a USB OTG camera, so I cannot use the micro USB port to charge the phone at the same time (or can I), so I tried ironing the power wires of the USB cable directly to he pins of the battery and it worked
I use a charger which provides power to the phone when the car engine is on, but the problem is that I need to turn on the phone manually every time...
Is there a way to make the phone boot automatically when it gets power?
I saw some threads for other phones which wanted to boot the phone when the charger was connected (not sure if that would be helpful for me but anyway). They achieved that by modifying a file called lpm in system/bin. However my phone doesn't have such file...
Thanks in advance for your help!
I found a file called pm and editted that one but nothing changed...
Help please!!!
