Not really.  6-7 of those ports could be operating on one USB Hub or PCI
card.  Try to connect it directly to the actual PCI interface instead of
using a HUB.  Also, be aware of faulty or using too long of a cable.

As for me, I've had my old PVRUSB2 working on a 50 foot Belkin USB cable
without too many issues.

Check for loose connectors too.

Again, I haven't had many issues with USB or even Firewire connectors.
The only real problem has been poorly designed or cheap addon hubs or
poorly designed/cheap USB hard drive enclosures.  One or two loose USB
connectors/ports.  And the problem with laptops pcmcia USB ports not
being able to support full-power usb devices without an additional usage
of a (wallwart) power supply.
