Hi!

I tried a couple usb 2.0 cards but but some things like the pinnacle
usb TV has signal dropouts. I do not know the exact cause of this.

How about the USB host controller? Whose USB 2.0 controller is on this card?

I've had the best results with the NEC-based cards. The VIA ones work "most
of the time" but sometimes they act strangely. And, as the chipsets from VIA
are the cheapest out there, you can find that the quality of the card you
used is lacking.

Never heard of Athena power supplies...not saying they aren't perfectly
good, but you ought to be sure it's honestly specified! Dell's power
supplies from this timeframe are of good if not excellent quality and will
produce more power than the rating suggests.
