Rich In general, if the plug fits you can plug in anything anywhere. Usually it’ll run just fine. Higher speed ports are generally backward compatible, and most older slow devices will work in a faster port. Now the key is SPEED. It makes no sense to plug a keyboard or mouse ( usually USB 1.1 or 2) into a usb 3.x port. you should match the external Device speed with the port. Why plug a usb 3.1 gen 2 external hard drive into usb 2? It’s just that simple. Not rocket science. -Ed _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
