Hello,

iam having problems of comiling the kernel. The Patch had issues with
android.c, so i tried to fix it manualy. there are some light differences
in the android.c.

Now when i try to compile i get the following error:
../../../../../../kernel/samsung/hlte/drivers/usb/gadget/android.c: In
function 'functions_store':
../../../../../../kernel/samsung/hlte/drivers/usb/gadget/android.c:2758:16:

ahh thank you very much for the fast answer and the Link i will give the new one a try. Just found out which line of code the problem was:

its: android_enable_function(dev, "hid"); It should be android_enable_function(dev, conf, "hid");

from android-keyboard-gadget.

Okay, ive got it to work. Thank you very much for this great app.

Btw. is there a way to send clipboard from a bashscript to the connected computer ? Iam just starting with kernelcompiling and programming, so for me making an app which simple send the clipboard when its startet and ends himself is a very big project for me :)

edit: cant type german umlauts and special signs (f.e. äö #). is there a way to enhance this ?

I've added description of the binary protocol to my github page few days
ago:
https://github.com/pelya/android-keyboard-gadget/

You can use this commandline tool to send key events:
https://github.com/pelya/android-keyboard-gadget/tree/master/hid-gadget-test

I don't know how to access Android clipboard from command line.

My app already has a clipboard button, if that will help you, you can just
take it's sources and butcher all other functionality from it.

@NeverUsedID would you send me the patch files you used please. I also would like to make sure that you are using Samsung Note 3 with cyangonmod installed and you edited in the kernel code in /kernel/samsung/hlte/
right?
