    Hi, I have a 22mini-ex board here that supposedly uses the ps2avrGB firmware, and I’m getting the “Device Descriptor Request Failed” error. This board was confirmed working in the past – so I’m sure it’s not the soldering of the PCB. I’ve tried holding the U key while plugging in, and nothing changes.

    In addition, if I flash the ps2avrGB4U-aikon firmware, it’s recognized as a HID keyboard input device – bootmapper client can download keymaps from the keyboard, but can’t upload anything to it. If I flash regular ps2avrGB or ps2avrU firmware, one of the led blinks and I get the error.

    Hi

    I think your board is 22mini-ex which has nothing to do with Winkeyless.

    Please contact

    I’ve tried contacting him, but he’s currently and will be unreachable for a long time. I figured that the firmware is essentially the same as the PCB is quite simple.
