Trying to compile a kernel for CM 11 and Samsung Note 3

Hello,

thank you very much for great idea and code. My idea of this usb mode is to use it with keypass2Android. It would be an outstanding feature to simply plugging the phone into usb and select (or copy to clipboard) the username/password from keypass or any other passwordstore and send it to your pc.

But for now iam having problems of compiling 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: warning: passing argument 2 of 'android_enable_function' from incompatible pointer type [enabled by default] error, forbidden warning: android.c:2758 make[5]: * [drivers/usb/gadget/android.o] Error 1 make[4]: * [drivers/usb/gadget] Error 2 make[3]: *\ [drivers/usb] Error 2

BTW. Iam very new dot kernelcompiling :=)

best regards...

You may try to apply this patch, it was adopted for newer kernel:

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");

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. On Jul 3, 2014 11:51 PM, "NeverUsedID" notifications@github.com wrote:

@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?
