USB to PS/2 Keyboard and Mouse adapter enables PS/2 type keyboards and mice to connect to a PC, notebook, laptop, or handheld computing device that supports USB. An advantage for notebooks is that an external mouse and keyboard can be connected at the same time without causing conflicts. The GUC10KM comes with two standard 6-pin mini DIN female connectors for the PS/2 keyboard and PS/2 mouse to plug into, and has an attached 16" USB cable with a type-A plug for connection to the PC's USB port, or to a USB hub. For further convenience - especially to users of notebooks, laptops, and handhelds - the GUC10KM adapter derives its operating power from the Universal Serial Bus itself, so no bulky external power supply needs to be taken along. And because it is a USB Specification compliant device, the GUC10KM supports energy-saving suspend and resume operations. -Works with any USB compliant system with PS/2 Keyboard and PS/2 Mouse Ports -Supports wheel mice -Keyboard and mouse can be attached to portable computer simultaneously -USB Bus Powered -Requires no IRQs
