Oliver, does the presence of the "Read Capacity(16)" message here
indicate that either the quirk was not applied to the device or that
the patch didn't have the expected effect?

(Is there any way to check what quirks flags are actually in effect for
a device attached to the UAS driver?  For the usb-storage driver there's
both a "Quirks match for vid..." dmesg line and the Quirks: line in the 
/proc/scsi/usb-storage/* file -- but neither of those seem to exist for
the UAS driver....)
