I am looking for a way in Fedora 14 to restart the USB system so that all USB devices disconnect and reconnect to the OS (due to some slightly dubious USB peripherals that I have no choice but to use).
I found that one way is to use
modprobe on ehci_hcd, but in Fedora ehci is built in. I found how to stop ehci by doing:
echo -n "0000:00:xx.x" > /sys/bus/pci/drivers/ehci_hcd/unbind
Where xx.x corresponds to the results of:
lspci|grep -i ehci
But I am not sure how to get it back up and running again. What should I do?
