Or possibly something has gone wrong with the motherboard's on-board "rate-matching" hub. To rule out software issues, you could try running an earlier kernel version. If that doesn't show any problems then you may want to perform a git bisection. As far as I know there have been no recent changes to ehci-hcd or ehci-pci that could cause this to happen. Alan Stern
