Very Computer

My USB controller is enabled in the BIOS but Linux does not see an
interrupt line for it.

Loading usb-ohci fails because of not seeing an interrupt. Kernel is
2.2.16 (SuSE 7.0), MSI-5169 motherboard with ALi15X3 chipset,
AMD-K6-II-350, 128MB.

I installed Windows for testing and USB works, so it should not be a
direct hardware/BIOS related problem.

Any help?

TIA Rolf

Maybe USB or USB IRQ is disabled in the BIOS, enable it.

<shot type="in the dark">
The last time I messed around with USB and Linux, I found there were two
options I had to set to "YES" in the BIOS:  "Enable USB" and "Assign IRQ
for USB".  If I set the first but not the second, the kernel would see
the USB UHCI device, but not be able to do anything with it, similar to
what you found.  This took me a few minutes to figure out because the
BIOS on my board (Epox VIA MVP3G2) has a lot of (poorly documented)
options.

Win9x wasn't affected by the "Assign IRQ for USB" setting--could've been
that PnP OS thing interfering with "normal" operations....

I found that I had to turn off the bios setting for pnp OS, to get Suse 7.0
to see the usb.
