Knoppix 3.2/ Nforce2 and USB

**RealNeo** · 04-23-2003, 09:04 AM

Hey Guys,

I'm in big Trouble with my USB-Ports on 8rda+! They don't work

!
But the Problem are not the driver, i think! The Problem is, they don't have any IRQ in Bios or in the PCI List at startup! only N/A stands for the USB-Hostcontr.-IRQ! And in the Bios i don't find any options to change that! (Xp runs very well with that) I tried "noapic" at startup...

! There are any "driver-tricks" in knoppix to solve that problem?
Thanks for help!

Have you disabled plug n pray?

You can boot 'pci=biosirq'.

'lsmod' to see which modules are loaded.

For USB you'll need the CORE & UHCI or OHCI (there are others too).

'cat /proc/pci' to see whats recognized on the PCI bus.

What version of USB?

...The Problem was that my actual bios don't allow to disable PnP!
every modul was loaded well! But the main problem was the 3Com NIC!
Pulled it out ...and it's working!

Thx 4 Help

I don't know if it's true for all 3com NICs but I have some ISA's that you can hard code the IRQ w/ a utility from 3com. Of course you'd want to assign one that Linux isn't using if you can!

Glad you got it working.
