The Palm Novacom Windows driver is a software component used to enable communication between a Palm OS device (such as a Palm PDA or smartphone) and a Windows computer. Novacom is the name of the driver and USB communication stack used by Palm devices to facilitate syncing, transferring files, and using other features like troubleshooting or app development. It was introduced with Palm's newer devices such as the Palm Pre and Palm Pixi, which ran the webOS operating system (as opposed to Palm OS used in earlier devices).
