The 2.4 kernels include two different UHCI drivers: usb-uhci and uhci. Have you tried using both of them? As far as I know, uhci is extremely similar to 2.6.0's uhci-hcd. If your system doesn't hang with 2.4/uhci but it does hang with 2.6.0/uhci-hcd, that's a good indication the problem lies somewhere other than in the UHCI driver. > > Have you turned off the BIOS settings for Legacy USB support? > > Yes.

I can't see anything wrong with it. I don't know what could be causing your problem. Do you want to try a diagnostic patch to see if the uhci-hcd interrupt routine gets called when you plug in a device? Can you buy a PCI USB card and use it instead of the USB controller on your motherboard? It might allow you to bypass this problem, and it will also give you USB 2.0 capability.
