Q1:

Once the system is already up..

- either booted without the cameras or

- booted with them initially on the nForce internal

What happens if the cameras are THEN plugged in to the Belkin?


Q2:

- Will the boot complete normally with just ONE camera on the Belkin?

- If so, how about TWO?

If one or two work, but NOT three, I'd suspect the current drain of 
three cameras is too much for the Belkin to handle AND still keep its 
bus conversations noise-free, clean-edged and within voltage and timing 
tolerance.

If so, the 'fixed for sure' is not software.  it would need a stronger 
attach pount (nForce), second Belkin, fewer cameras, or ...

. . external *powered* USB hub.

An oscilloscope would confirm that - but you probably arent in Hong 
Kong, so mine is no use.
