I'm trying to get USB to work on my laptop (Ali Magik1 chipset, OHCI
controller).. it appears that no matter what i do, no IRQ's are getting
through... the OHCI controller shows up on IRQ9 and is shared by ACPI.
This is the same as it is in windows.. Under windows USB works (but
'pauses' for a few seconds every couple of minutes, bus reset?).
everything else on the laptop is set to IRQ11. (well, enet, cardbus,
video). I tried using setpci to change the USB irq to something unused
(IRQ3).. but that didn't work (unless you use 'lspci -b' to show bus
view).. either way it didn't work in practice.
Using the dump_pirq program from pcmcia-cs, i get the following output:

If i'm reading this correctly, the board is wired up for USB to use irq
11, not irq 9...but everything wants it to use irq9. Without bios
support, what can I do? Is linux's interpretation of the ALi PIRQ tables
incorrect?
Other files of interest follow.. any feedback would be appreciated.

On many systems USB is an internal IRQ route, not configurable through PIRQ
at all, despite what the PIRQ table tells you.
Just a possibility.
