Are you running an intel/uhci or an amd/ohci system?

I have had problems with recent kernels (2.6.26.3, 2.6.26.5, 2.6.27-rc7)
with usb on a new amd-phenom machine. Read errors, hung devices etc.
The problem went away when I disconnected my monitor hub. It didn't
matter if anything was actually connected to the hub, having the hub
plugged in was enough to kill all the other usb traffic. But the same
hub works perfectly well when connected to an old intel machine running
2.6.25.5.

Note: the above-mentioned usb problems have nothing to do with pvrusb2,
any usb device (flash stick, disk drive, etc) triggered it.
