At the final uhub1:, the cursor sits to the right of the colon and the system is frozen. I have 3 USB video cameras plugged into these three ports. If I unplug the cameras, DragonFly boots fine so the problem isn't the actual 4 USB port PCI card, but rather the USB cameras plugged into the USB ports of this PCI card, a Belkin FU220 ????

If these same USB cameras are plugged into the onboard USB controller
(nForce 430 chipset), DragonFly boot fine as well. This problem needs
to be fixed for sure. HTH


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?


- 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.
