# usb_detach
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:
```bash
make clean && make
```
## 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.
