This is an older RS232 Serial Trackball, QuickShot - manufactured by Bondwell Industrial Ltd., FCC ID CTX7X9QS141. When connected to a Windows 7 machine with a serial port, it is found as a Microsoft Serial Mouse - the trackball moves the pointer around and the buttons click - but the cursor hesitates when the trackball is moved - it could use a cleaning/adjustment possibly. This is sold as-is for a collectible only.
