Try with the attached patch (and probably with dcache off)
The patch applied cleanly. The behavior is unchanged with both dcache on and off. The "good" sticks still work, and "bad" sticks still don't.
OK. Then I should probably go hunting for Kingston DataTraveler SE9, right ? Can you give me a link to the stick you have, so I know what crappy device to look for ? Thanks!
Here it is [1] - I have the 8GB version.
I think there will always be crappy sticks that don't work... but do you have any advice as to what properties will/might generally cause a problem?

I have exactly this stick here (16GiB) version. And it is detected just fine in both, current mainline Armada XP (theadorable) and x86 boards (conga-qeval20-qa3-e3845). Here my lsusb output:

HTP.
Thanks, Stefan
FYI - here is the verbose lsusb output for this particular device for what it's worth:
