There is; you can do it through sysfs. For example on my system: # cd /sys/bus/pci/drivers/ehci_hcd # ls 0000:00:1d.7@ 0000:01:00.2@ 0000:01:01.2@ bind module@ new_id unbind You just have to identify which PCI device corresponds to the controller you want to disable, and write that name to the "unbind" file. For example: # ls -d 0000:00:1d.7/usb* 0000:00:1d.7/usb8/ 0000:00:1d.7/usb_host:usb_host8@ # echo -n 0000:00:1d.7 >unbind would disable the EHCI controller for my USB bus 8.
