While using CH Products USB Yoke, whenever I change from one of the AP modes to another (heading to NAV) or disengage AP plane rolls left and dives. It takes unpluging and and repluging the yoke to regain yoke functionality. Sometimes I can revover (from FL240), low and slow (approach) toast. I am using the latest nVidia drivers on a 7600GS 512med video card and Intel Core Duo 3.2ghz 2 gig Ram.Any ideas would be appreciated.ThanksMike

Spoke with CH Products rep and he told me to disable te USB power saving setting in the device manager USB Root. This seems to work.Mike
