The PCB is not recognised in devices.
- ensure the backspace is held down prior to connecting the board to the PC/mac
- check in device manager(windows) or system information(macOS) for HIDBoot when in bootloader mode
Bootmapper Client says it does not recognise ps2avrGB device
- the incorrect firmware has been flashed to the PCB
- download the latest version from https://github.com/showjean/ps2avrU/releases
- confirm it is ps2avrGB_firmware_vX...zip
- unzip the files and when you select firm up, choose the file that is ps2avrGB_NKRO.hex
Some keys are not recognised - usually backspace, pipe, enter, up arrow, right arrow
- Culprit is the screw-in stabs at the backspace key is shorting the entire column to ground
- Fix: add some sticky tape under the screws, just enough to cover the pads.
