The CRU-DataPort Mouse Jiggler 30200-0100-0011 is a USB device that generates mouse activity to help keep a computer from becoming idle, activating a screen saver, or going to sleep. It can be useful during presentations or while a program is downloading or installing, when an unwanted idle state would interrupt the session.
It registers as a Human Interface Device (HID) and needs no additional software. The interface supports USB 1.1/2.0, and the listing names Windows, Mac OS, and HID-compliant operating systems. A single integrated LED counts the minutes the device has been working. The listing also describes fast and slow versions, letting the user choose the pointer movement speed.
