I have recently purchased and installed the Adaptec DuoConnect PCI USB 2.0 / Firewire card. Installation seemed to go fine. I have an HP Photosmart 7550 connected to it, to a Dell Dimension 8200. I'm getting a message in the USBControl GUI, that states my "system is not performance optimized", and that my printer "is not working at optimum speed". I assume that means something in regards to USB 2.0. I'm running XP with SP1, so I should have USB 2.0 support. Has anyone else experienced this?? Any suggestions for a fix. Dell does not specifically address USB 2.0 on their web-site. Help!! Thanks!!!!
