[PATCH] hid kernel module for wireless remote LC Power model RC1000MCE
From: chris schlund <hidden>
Date: 2011-01-24 16:52:00
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 39$ cat lc-power.patch diff -urN linux-2.6.37/drivers/hid/hid-core.c linux/drivers/hid/hid-core.c
