 FYI, I came across a WD My Passport USB drive that has a different product ID, 
 yet requires the same UQ_MSC_NO_SYNC_CACHE quirk:
 $ usbconfig dump_device_quirks | fgrep -i 0x07a8
 VID=0x1058 PID=0x07a8 REVLO=0x1033 REVHI=0x1033 QUIRK=UQ_MSC_NO_SYNC_CACHE

 The part number printed on the case is WDBBEP0010BBK-03.
 Please augment the patch to accommodate this model as well.   Thanks.
