Hmm... it looks like it's not host dependent unfortunately. We have a
(private) bug report for RHEL 6 where a customer wants to use the
following mouse:

I bought one and was able to reproduce the need for the quirk on
various systems.

Plus I noticed that if the mouse is raised over the surface (so the
sensor does not report anything), the bug does not appear.

So, to me, the USB output queue is full given that it is not polled by
the host and the chip within the USB mouse decides to
disconnect/reconnect to empty the queue. So nothing host specific.

I am not questioning at all that it's needed for some devices.

But I am surprised by all-of-a-sudden flow for quirk addition for many 
distinct devices, all coming from the same source. I am afraid this might 
be false positive, and root-cause being somewhere else, causing us adding 
a lot of potentially unnecessary quirk entries.
