| 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. | ||
