Bug Description

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.

This is what Kinfocenter tells me about the scanner:

The bug report should be changed to "need driver for quickcam pro".

The camera is being reported as usb 1.1 because the camera is using vendor-specific protocol.
Using usb 1.1 to communicate with the device is the default behaviour. When a driver
is found for the camera, it will claim the device and use high speed.
This is not a bug with USB.

The camera uses the gspca driver. The driver definitely gets loaded because I can watch the video stream it produces in ekiga etc. The problem is that I can only get the stream at low resolution because of the narrow bandwidth of usb 1.1.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

I am currently using Hardy and I am still getting the same problem unfortunately.
