I didn't just notice that the IRQs were the same - I checked for it specifically. What I noticed was that the printer wasn't working, and lpq showed it as possibly offline. When I first installed the USB printer, I had the exact same problem - until I changed changed the hardware config so that the fxp and uhci weren't using the same IRQ. That's why I checked for this case. > > Anyone got a clue as to why the IRQ would change? Is there anything in > > FreeBSD that could change it? > Has it actually changed? I'm still trying to figure that one out. I haven't been able to get a config with the fxp and uhci on different IRQs. I've got a doctor's appointment, after which I'm going to pull the fxp and see how that goes.
