[Q] Do any of the current roms have USB HOST/USB OTG support ?

Would love to see this added to the G2 I have been trying to find out a way to connect a USB MIMO touchscreen to the G2 in order to make a car dock for it . Here is an example of USB host working on android http://sven.killig.de/android/N1/2.2/usb_host/ would this work for other phones ?

Hi, i'am also interested in this, is it possible to apply the kernel patch to the g2 ?
I've never compiled Android Kernels before, but i will try if someone here tells me it would work

[Q] OTG Problem (Maguro)

Hey guys i got a problem with my OTG and my Maguro.
I'm running CM10.1 16th nightly with Anarkia Purity Kernel v12. When i connect my wireless mouse, that has an usb receptor the phone doesn't recogniced it. The same thing with an 32gb micro sd with a usb microsd reader. I have downloaded ChainFire's app, but i only have solution for the microsd, not for the mouse. Now, the problem is that i want to buy an usb PS joystick. It's wireless like the mouse (has a receptor), and i wish it could work. Anyone has an answer to my problem ? A recommendation of configuration (especific ROM + especific KERNEL) will be also apreciated.
Sorry for my awfull english.
Thanks in advance !

pls !
pls guys i really need your help !

Since you're not using CM stock kernel, talk to your kernel Dev to support your wireless receptor. It's probably missing the module to support it. Check dmesg.

Thanks for your answer, my friend.

Tab 3 3g sm-311 and Asix AX88772A usb pan with OTG

Hi to all friends.
I just bought an Samsung Galaxy Tab 3 3g sm-311 and I have a request for help.
I just rooted it and it works fine.
In my job they do not use wifi and I am in the need to use internet through my tab 3.
I already own a usb Lan card with asix chipset (AX88772A) that works fine with any pc and mac I ever used. Many people have connect it with OTG cable. It detects it but no drivers re installed in the tablet.
They provide drivers For Android 1.x/2.x/3.x/4.x, Linux kernel 2.6.14 and later that needs to be compiled to kernel.
I do not have the knowledge to do that. Can someone help me out on that and explain how I will put back the kernel ?
I would like to thank everyone in advance .
Best Regards

Anyone ?

Umm.... I think everyone with the 7 inch model of the Tab 3 is having that issue..... Some of us think that it will come through an uupdate or somthing.... Otherwise iv tried to push the persmissions using a xml file which says its detected and thats all....Still dosnt work...:crying:

You can download PPP Widget from the Play Store. Samsung devices lack the Option driver in the stock kernel, so you might need to get that separately. They don't need to be compiled into the kernel. You can have them as loadable modules. The forums on draisberghof.de may provide a link.
The ability to load kernel modules has been removed from the stock Android kernel from Android 4.3 onwards, which sucks, but we can always use a recompiled kernel.

No lack..... do you think that I should contact samsung ?

What have you tried? Did you get the drivers? Samsung will be unable to help except point you at their kernel source, if they do respond.
Please check this thread on the usb_modeswitch forum and request Josh for drivers for the specific kernel for the Tab.

Its too bad that I can nor find a solution. I will be forced to sale the unit and buy a win8.1 tablet like toshiba encore.

how do i connect a Logitech K700 to a nexus 7?

I tried connecting it to my moto G and it worked flawlessly but i cant get it to work on my nexus 7. I wanted to know if there was a way to get it to work without root if its possible, also, my knowleadge on android development is pretty low so i would thank you if you explain step by step or tell what i should learn to do it.
Thanks a lot
Ps. i have the 2013 model (2nd gen)

You will need a custom kernel with in built logitech's unifying driver. ElementalX (since ver 2.14) has it implemented, and it works.
So you first have to unlock the bootloader and then flash this custom kernel.

[Q] uvc driver on T705 using dashcam and UsbWebカメラ

Hi Guys,
I'm trying to get my new usb microscope working on may Tab S 8.4 4.4.2. stock with root.
Cam is DigiMicro 2.0 Scale (dnt.de)
I only get UsbWebカメラ working but just up to 800x600 Resolution. 720p is max available but doens't work. The Scope supports up to 1600x1280 (2MP).
Also, there are two devices shown in list, just the second one works.
This App worked also before rooting the device.
Dashcam never worked .. asked for access to device but shows nothing.
Same on my Note II with Phoenix Rom v18.8 Android 4.4.2
I read about the uvc driver that is necessary to get usb webcam working over USB-TG.
So when UsbWebカメラ works (limited but works), uvc driver should be on my devices and access possible because of root. Am i right?
But why limited and why doesn't Dashcam work?
Hoping you guys can help me with any tips to get the scope proper working, that would be really awesome!
Cheers!

My guess is that kernel needs a recompile with UVC driver enabled.
I have asked in the Skyhigh Kernel thread to incorporate it:
