# 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.
