usb keyboard not working during or after boot up of asus sabretooth z87 mobo
new build, intel i7 4770k, asus sabretooth z87 mobo, keyboard is a micro-soft digital media pro key board. I can unplug the keyboard after boot and the device will start once I have re-inserted the usb to the mother board. every other external device functions properly after boot up except the keyboard.
After taking the time to further trouble shoot the situation, all peripheral buttons on the keyboard work. The key pad and the letters are not functioning unless I unplug the usb connector and re-insert it. Must be the keyboard that is causing the problems. Thanks for all the imput and to raga from Asus for the timely responses. You are a star....
