If there is a glitch on the line (electromagnetic interference), the 
controller will likely do all retries while the glitch is active....

IMHO this is bad behaviour: a retry should not be done until the error 
situation is removed. But this stupid hardware doesn't know better.

So you are better off doing some retries in software if you get
EILSEQ from UHCI.
