I have traced the USB communication and it gets as far as it polling for new data, but never gets any. It is all detected, instantiated properly, and so forth – just doesn’t get data. So, as suggested, a protocol issue. The keyboard I’m using reports itself as subclass BOOTIF and protocol KEYBOARD so I think it ought to work.
That said, the HID keyboard driver is also broken as multiple plugs/unplugs causes a crash. I’m thinking memory leak but not investigated yet.
