Re: Problems with p55-express and sleeping usb-hds

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
