Most likely.

The EHCI device claims to be buggy in 5.3 and 5.4.  You might try
disabling it to see if the drive is correctly classified when it is
handled by the UHCI device.  Actually, I don't even know if those are
the drivers that do the device classification, but in the absence of
that information, it seems worth a try.
