I have read some reports (and not only in Debian) on this. E.g.,:
linux-image-2.6.38-2-amd64: xhci_hcd USB 3.0 not working properly
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=623004
Blacklisting the involved module "xhci_hcd" is a workaround that could
solve your issue during a time but better if add your findings to a bug
report so the problem can be properly solved and other users can also
benefit from it :-)
