Hello,

I've done some more tests and have some more findings.

After the problem occured (which looks for me like a timeout during a 
wait for a CSW), ehci_hcd doesn't work anymore. Low- and full-speed 
devices are still working and are recognized correctly, but no 
high-speed device. After unloading ehci_hcd and reloading it, high-speed 
devices are recognized correctly again.
As unloading is no option for kernels which have ehci_hcd compiled in 
(like the F11-kernel), is there another option to reset the driver?

Regards,

Alexander
