I accidentally noticed this error written to the warn log on my Dell 
R200's when the machines booted up after latest kernel update. Google 
doesn't have this exact error, only a few with differently named devices, 
but all seem to have to do with USB. 
Could this be a bug?
Didn't see this error on other machines with more than one USB port, 
though.
