Dear Bjorn, >From this URL link and at the bottom of it, it says: "To resolve conflicts with PCI or ISA cards try manually setting them in your motherboard's BIOS or try a different slot for the newly installed device, you will usually find that by changing the slot you will change the IRQ channel as well." You may reorder and much simplify the number of PCI boards on your PCI bus by removing all useless. Some of them being needless and conflicting may be removed using your motherboard BIOS. Your PCI bus seems to be full. To avoid IRQ conflicts between your USBs and your Nvidia graphic board you might perhaps move it to another slot. - http://vouters.dyndns.org:8080/ Philippe Vouters (Fontainebleau/France)
