Thanks for the help (Eric, Matt, and Josh). I should have mentioned I was
already running as root. I typed in /sbin/lsmod | grep ehci and did see
ehci_hcd. So I also tried the UdevConfig, still with no luck. My coworker had a
2.0 USB PCMCIA card for his laptop and we just so happened to have a PCI to
PCMCIA controller card lying around. The only downside is that I don't think
it's running at full speed- 16MB/sec and 32MB/sec failed on the
benchmark_usb.py program and when running the oscilloscope I notice clipping.
I guess I have to find a better PCI card that will support 32MB/sec before I
can really get this baby cooking.
Thanks again!
Randy

This also happens if you're machine does not support USB 2.0
If you try:
$ /sbin/lsmod | grep ehci
ehci_hcd 31880 0
usbcore 115716 4 usbhid,ehci_hcd,uhci_hcd
Do you see an entry for ehci_hdc? If not, your machine probably
doesn't support USB 2.0. The USRP requires USB 2.0
