[2.6.9] unhandled OHCI IRQs...

From: Daniel Blueman

When plugging in an Epson C62 USB 1.1 printer to my nForce 2 OHCI + EHCI USB
controllers, the IRQ doesn't seem to get handled [1]. Tried both with
acpi=noirq and without, printer support and full USB support enabled. Kernel
is 2.6.9.

Any ideas?
