You can try sysutils/kdpatch to patch the quirks table for
umass. As far as I can tell the table has the same format
in usb2 and usb1 so the following should work:

kldpatch umass.ko - _at_0 0x10d6 0x0000xxxx 0xffffffff 0x0201 0x4200

(replace xxxx with the usb product id for your device).
0x201 means use ATAPI commands over BBB protocol which is what
      your messages say. Perhaps 0x101 also works here.

0x4000 means the following:
        /* Device cannot handle a SCSI synchronize cache command.  Normally
         * this quirk would be handled in the cam layer, but for IDE bridges
         * we need to associate the quirk with the bridge and not the
         * underlying disk device.  This is handled by faking a success result.
         */
	#       define NO_SYNCHRONIZE_CACHE     0x4000

you may have to play with different flags and quirks to make the
thing work.
