More details about the USB performance in terms of numbers you are seeing from some benchmark would be very useful.

I agree. How can I benchmark my just my USB controller?

Using a mass storage device like an external hard drive is probably the best bet. In the message you replied to, I made some suggestions with regard to using iozone, or dd, etc.

Right now all I can say is that I've got a Netgear FA120 network interface plugged into a USB port and I can't squeeze more than 4Mb/s out of it. It's USB 2.0 compliant and should get close to 100Mb/s. I get faster results out of my old 10Mb ISA card.

That almost sounds like the NIC is running at USB 1.1 speeds, yes. Note that you won't generally see more than about 90% utilization for network devices due to protocol overhead and latency, but you ought to be getting something closer to 50-80 Mbs...
