Thanks to everyone for your replies - I have convinced the card
manufacturer that this is a problem in their PCI driver, and they are
fixing it.
Cheers,
Steve.

The Hub driver is getting not responding errors, probably because
the PCI card has locked up the bus. It the proceeds to reset
itself, which resets all the devices downstream of it. What
happens if you plug in the serial adapter to the root hub?

This suggests to me that the camera card (made by Roper) is timing

The odd thing is that the PCI card works fine with a different
(much slower) camera. I'm wondering whether the developers of the
Roper PCI driver are doing something odd to try and recover from
this timeout they've logged, which is in turn affecting the USB
host controller.
