Hello,
I have the same problem on the Sony Vaio FX (205/209/301/302 - all
identical). Let me tell
you:
This is not an IRQ conflict between different devices !!! I tried this,
when only usb-uhci was running on IRQ#9.
This happens if you plug _any_ USB device (powered or not does not mind)
to this notebook under
Linux, even if there are no other devices (eth, sound) running on that
IRQ#9. In that case you have only two usb-uhci devices running on IRQ 9.
I describe this problem extensively in my new posting "USB support for
i815E/823820 820 (Camino
2) ?", where I ask if there is a support for this chip which is build in
in my notebook.
Any advice ?
I don't know if this would be a solution, but has anyone an idea, if it
is possible to assign
different interrupts to the two usb-uhci modules running on IRQ#9 ? The
module usb-uhci.o has no
parameters, so I dont'now.
I'm running SuSE 7.2 - so it is distribution independent. I checked it
to be hardware independent, BIOS option (PnP) independent, and
IRQ-conflict-between-DIFFERENT-devices independent. So, I ask for the
correctness of the driver for this chipset (see above) !
Any Ideas ?
