*Some notebook computers, notably the IBM® Thinkpad® and Toshiba® Tecra®, have trouble working with a switch when their mouse and keyboard ports are used simultaneously. To avoid this problem, only connect the mouse port or the keyboard port to the Switch. If you connect the mouse port, you will need to use the notebook’s keyboard when the notebook is the active computer. These switches are designed to work with PS/2 keyboards. Older XT

(84 key) and AT keyboards will not work.
