Do USB devices use IRQ's?

[Blue Knight]

Just asking if my USB devices also use IRQ's.

Trying to setup a linux box using ndiswrapper and a wireless usb device. The error screens I'm getting could be because of IRQ sharing...if this is the case, is there anyway to manually select the IRQ of a USB device? (It's not PCI, so I can't move it around empty slots - it's also a shuttle box, so there's no free options).

No, but your USB controller does. I doubt IRQ sharing is the cause of your problem, though. It looks like I've got seven devices on IRQ11 and three on IRQ5. My USB1 and USB2 controllers share IRQ11 with a couple IDE channels(pci card), tv tuner card and tvaudio, and my video card. So unless there you have a device that just doesn't work with IRQ sharing, then that's probably not the problem.
