Umm, you *configure* the PCIC controller to interrupt wherever you want it to. It's not hard-coded like an ISA card, but completely programmable. Just because Windoze chose to program it to IRQ 11 doesn't mean it must be an IRQ 11. > > > > I had a similar problem with ep0 and an HP Omnibook.

Never tried ... I like things to "just work". Sure. It should 'just work' assuming there isn't any hardware hard-wired to a particular IRQ that FreeBSD doesn't know about. > > > > ep0 just wouldn't work on 10 (due to the pcic listening there).
