Hmm. Looks like a hub as well as a storage device. I'm not too sure
what impact that might have.

I don't think the quirk is right. I'd try:

Also, you either need to append a comma to the close brace (if this is
inserted in the list of quirks) or append a comma to the prior entry
if you are placing this at the end of the quirks. (I suspect that you
did this, but it is not clear.)
I'm not too sure how many of the fixes in 5.0 have been MFC'ed to
STABLE. The 5.0 USB code has had a lot of work of late and most flash
drives just work, now. I imagine that most of these will get to STABLE
soon. The 10 byte command issue was just resolved in current last
week, so it should make it into STABLE in a couple of weeks unless
there is an issue with STABLE that I m not aware of.
If I missed something obvious, perhaps someone else can point it out.
