Try
modprobe -r ehci_hcd
and connect the camera again. It seems that this module can cause
problems with certain controllers, devices, ports or cables. For more
information, see here:
https://bugs.edge.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/88746
http://www.linux-usb.org/FAQ.html#ts6
You could also try if the 2.6.27 kernel improves the situation. (What
you report in your other mail indicates that WinXP can operate the
device at normal USB 2.0 speeds, so it would be annoying if Linux
restricted you to USB 1.1 speeds.)
