4 | |||
5 | 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. | ||
6 | This program can force Linux to give up a device, so that the programming script can reset it. | ||
7 | |||
8 | ### To compile: | ||
9 | ``` | ||
10 | gcc usb_detach.c -o usb_detach | ||
11 | ``` | ||
12 | |||
13 | ### To run: | ||
14 | 1. Use `lsusb` to discover the Bus and Device numbers for your keyboard. | ||
15 | 2. Run the program: `sudo ./usb_detach /dev/bus/usb/<BUS>/<DEVICE>`. | ||
16 | 3. Build and program the firmware as normal. | ||
