 Well, that was what you said first, and it has a well-known
 explanation (though apparently not well-enough known; can you think of
 anywhere this behavior should have been documented that you would have
 seen it while investigating?)
 
 I suppose ums(4) would be a good starting point. The current ums(4)
 seems to be about two sentences...

 No. One's enough, no reason it can't be this one.
 
 However, we do need to know more about the device in order to do
 anything about it, since we don't have one. A copy of the messages
 that get printed when you plug in the device (or at boot time) is
 a good starting point -- both the messages for the device itself and
 the usb plumbing (uhub, *hci, etc.) underneath it.
 
 Sorry everyone seems to have piled on you; that was unfortunate.
