This device is a gray USB parallel port adapter with "F5U002" imprinted on the plastic and a sticker that says both "F5U002" and "P80453-A". It's identified in lsusb as "05ab:1001 In-System Design BAYI Printer Class Support". It's subtly different from the other gray cable I have that has "F5U002 Rev 2" and "P80453-B" on its sticker and device ID 050d:0002. The uss720 driver appears to work flawlessly with this device, although the device evidently does not support ECP.
