--- Comment #1 from Milan Plzik (milan.plzik@gmail.com) ---
After doing some more testing, it turns out that even the dual-boot windows
wasn't able to use the USB controller correctly -- apparently there was a
damage to the EEPROM of the USB controller (first 0x84 bytes of the firmware
were followed by zeroes). Using a [firmware upload
tool](https://github.com/markusj/upd72020x-load) I was able to test and
re-upload correct firmware.
