>Well, perhaps, someone can help you with the information you provided, but to get a picture of what's your computer doing during such a hang, an ALT+SysRq+T could help (of course, you need SysRq's enabled in the kernel). Besides, usual outputs of /proc/bus/usb/devices, lspci, dmesg can help. You might try to run a loop

All my 'magic sysrq' keys become useless when the device is connected. I'll attatch the output requested below, but there is nothing in /proc/bus/usb/devices. The while loop you suggested to check the file prints nothing but 'No such file or directory' until the system hangs.
You might like to know that the whole setup works fine with a 2.4.18 kernel! But only works with the uhci driver, _not_ usb-uhci. The problem is there when using the 2.4.19 kernel (and others since then..) - I noticed there were quite a few changes made at that time, USB 2.0 added etc..
Hmm, again non-working VIA set_next_interrupt()?Is this comment worth looking into? I'll have a look for it, but could you tell me what you mean, or when it was fixed?
Thanks for your suggestions, Malcolm.
dmesg output (this is with a usb mouse plugged in, though I didn't bother with any mouse support in the kernel.. so I'm guessing that's why /proc/bus/usb is still empty?):
