Thanks, Rabeach. The drivers were selected. I finally tracked the problem down. This laptop has three USB ports. I was using one for the Keystation, one for the Saffire, and one for the Toshiba external drive. It seems that everything is fine when the Saffire and the keystation is plugged in. If you plug up the external drive everything goes haywire. I guess it's time to invest in a new USB hub. I think that will solve the problem. BTW, I was running the laptop, the Keystation, and the Saffire all off of the laptop battery and the battery powered it all for about 2 hours. That's steady recording and playing back, switching instruments, midi controller data, etc. I thought that was pretty good. If I ever go to the middle of the desert or a rainforest to work, I'll be set! LOL!
