I though this oddity was interesting in light of this thread. I have a firewire/USB 2.0 card and integrated USB 1.0 in my XP PC. I can connect to my empeg using the 1.0 USB with the RIOXDRV.SYS driver. When I plug into the 2.0 card, I get alternating errors of "The player appears to no longer be connected" when double clicking on a greyed out empeg icon in the "Select Player" Dialog. The other times emplode attempts to connect but fails at initialization.

I'm running developer 2.0-final firmware.
