usb: misc: uss720: add support for another variant of the Belkin F5U002
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.
