 Hardware Supported: YMD96 with the ATmega32a chip.  
 Hardware Availability: The GB was run June 2017, [in this thread](https://www.reddit.com/r/mechmarket/comments/6hu3yx/vendor_ymd96_gb_is_now_live_68_an_universal_and/). The vendor has stated that they plan on selling more rounds.
 
+A very big thanks to @krusli for making the RGB underglow, Backlight, CapsLock and NumLock LEDs working correctly.

 ## Finding your specific matrix
 
 This firmware was modified from [ps2avrGB](https://github.com/qmk/qmk_firmware/tree/master/keyboards/ps2avrGB), also found on this qmk repo, to work with the YMD96 keyboard. However, I only have one board to test with, which might have a different layout than yours. To get qmk working with your specific layout, you'll need to follow these steps:

+## usb_detach.c
+
+When trying to flash on Linux, you may encounter a "Resource Unavailable" error. This means that Linux's HID driver has taken exclusive control of the keyboard, and the program script can't flash it.
+This program can force Linux to give up a device, so that the programming script can reset it.
+
+### To compile:
+```
+gcc usb_detach.c -o usb_detach
+```
+
+### To run:
+1. Use `lsusb` to discover the Bus and Device numbers for your keyboard.
+2. Run the program: `sudo ./usb_detach /dev/bus/usb/<BUS>/<DEVICE>`.
+3. Build and program the firmware as normal.
