I'll test that next. Yep, I reverted that file to revision 1.31 and the hangs went away even with the USB IRQ disabled in the BIOS. The change in revison 1.32 apparently assumes that if no IRQ is assigned to the uhci device, the only possible reason is because PNP OS is turned on. But in my case the actual reason is different -- the IRQ is disabled in the BIOS. Is it feasible for the attach routine to distinguish between these two cases?
