Yeah, it grabs the interrupt in an unshared manner. If there is already a
driver sitting on there, it won't grab it.
The values are way to high if it is right after a reboot.
What all other interrupts rise the same speed as this one? Are there similar
values for any other interrupt number? Does it count even if you don't use usb
devices?

I did it. The "bimbo" module did sit on top of irq 16, but didn't seem to
work
for 18.

From /proc/interrupts after a reboot...
