Ok, I guess I should include more complete debug output. phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x09 failed for offset 0x0000 with error -32 phy0 -> rt73usb_validate_eeprom: EEPROM recover - MAC: 66:76:2b:e8:68:e7 phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x3000 with error -32 phy0 -> rt2x00_set_chip: Info - Chipset detected - rt: 1300, rf: 0000, rev: c03c0ae0 phy0 -> rt73usb_init_eeprom: Error - Invalid RF chipset detected ...so, I think hardware is indeed quite similar to what rt73usb driver expects...?
