Yeah, turns out the device really is a piece of CR*P like I figured. I
had to add this to get it to work:

UNUSUAL_DEV( 0x1908, 0x1315, 0x0000, 0x0000,
"BUILDWIN",
"Photo Frame",
US_SC_DEVICE, US_PR_DEVICE, NULL,
US_FL_GO_SLOW ),

after which the device showed up as a removable media device with an
iso9660 fs! Sheesh! And this fs of course just contained some utter
garbage software for Windows to upload pictures onto the device using
a proprietary HID interface. Can you say "what were they thinking?!"

Having given up at this point, I plugged it into a windows box, and
the thing basically gave windows a conniption fit. Yeah, I think I'll
be throwing it out now. What do you expect for a $9.95 trinket from
China? Sorry for wasting everyone's time.
