Re: USB mouse and keyboard disconnected
Hi,
looks like the problem is either with ehci_pci or ehci_hcd because if
I do "modprobe -rv ehci_pci" and "modprobe -v ehci_pci", then both
keyboard and mouse start to work. "ehci_hcd" is used by "ehci_pci":
ehci_pci 12512 0
ehci_hcd 69837 1 ehci_pci
Modinfo output for above-mentioned modules can be seen below:

Any ideas what might cause this issue?
thanks,
