Public bug reported:
When I plug my logitech quickcam chat into an NEC pci usb 2.0 card, it
is only recognised as a usb 1.1 device, even though it is in fact a usb
2.0 device. This leaves the camera fairly crippled because it is only
possible to capture video at very low resolution.
By contrast, my scanner is correctly recognised as a usb 2.0 device. I
have tried swapping the two devices about just in case it was a problem
with one particular usb port, but this did not make a difference.
Here's what dmesg gave me:

In Kinfocenter's listings of usb devices, the scanner is listed as being
subject to an EHCI host controller, whereas the camera appears to be
under an OHCI controller.
