According to lspci -v, I have one EHCI (2.0) and one OHCI (1.1) controller. usbview has output like this: OHCI - Philips - Philips EHCI - Brother If I unplug the Brother printer and plug a Philips webcam into the same slot the Brother was plugged into, usbview shows this: OHCI - Philips - Philips EHCI So it seems like the slots do not correlate to particular controllers. - Grant
