The problem still happens. irq 18 is dsiabled every now and then.
This time on different, new hardware.
The motherboard is now a Gigabyte F2A85X-UP4.
Camera is the same pwc cam.
Recently I removed the USB printer that was attached to the same USB

So probably it is not a hardware issue related to board or printer.
How to proceed next?
