Not that crap again. I don't why people keep sprouting this idiocy.
Plugging a slower device has no effect on the speed of any other device
on a USB system.
If the devices are attached directly to the computer the actually
attach to totally different busses.
If the devices are attached to the same (USB 2 compliant) hub, attached
to a USB 2 compliant host, all traffic from the host is at high speed.
The hub actually downshifts the speed and talks to the slower device,
independantly, and concurrently with any high speed traffic to other
devices on the bus.
No slowing down.
