no, I guess I'll try that (and using alternative uhci driver)

the problem is I cannot figure out how to change the IRQs - I have
abit VH6-II motherboard that has very confusing setup - I can set each
irq to be either pnp or legacy isa and there are 4 (or 5) groups of
devices (pirq 0 - 4), but the memebers of these groups are fixed, and of
of them contains eth and 2 usb devices...
btw I checked the /proc/interrupts - the count does not change when I
plug in/unplug USB device - is this the ultimate error? I mean if
there's no interrupt then nothing is going to work, right? at this point
it doesn't even matter which driver I use - or does it?
something's going on since I get the following messages when plug
in/unplug (3 for each) a usb device:
Dec 28 03:00:29 localhost kernel: hub.c: port 1 connection change
Dec 28 03:00:29 localhost kernel: hub.c: port 1, portstatus 300, change
3, 1.5 Mb/s
Dec 28 03:00:30 localhost kernel: hub.c: port 1 enable change, status
300
Dec 28 03:00:33 localhost kernel: hub.c: port 1 connection change
Dec 28 03:00:33 localhost kernel: hub.c: port 1, portstatus 301, change
1, 1.5 Mb/s
Dec 28 03:00:34 localhost kernel: hub.c: port 1, portstatus 300, change
0, 1.5 Mb/s
what should I see when it works? is it the irq problem, or, if it's
not clear yet, hot to make sure whether it's irq problem or not?
TIA
