Hi,
I bought a remote control LC Power RC1000MCE (usb rf keyboard). Some
keys were not working. Therefore I took the hid-topseed kernel module
copied it and prepared it as a new kernel module hid-lcpower which
provides the correct keymapping for this remote control.
I tested it on the 2.6.32 kernel.
I modified it to compile with the kernel version 2.6.37 (untested).
Sorry If I made some formal errors in here. This is my first patch and I
am not used to this process.
Thanks
Chris
