Abstract
A USB (universal serial bus) equipment plugging and unplugging reminding device for a public computer can be mounted on a HUB connecting wire of a USB or at a USB equipment end and a computer host end and comprises a USB interface, an integrated chip and an alarm. The integrated chip is connected with a power cord in the USB interface by the alarm, and simultaneously, a conductive contact sheet is disposed inside a USB equipment connecting end of the USB interface, so that the integrated chip and a USB flash disk can response synchronously by the aid of program setting when the USB equipment is connected. The problem that data are lost when a user forgets to unplug the USB equipment from the public computer can be effectively solved.
