5Turn off all attached USB devices and disconnect them from the system.

6Restart the system and, if your keyboard is functioning, enter the system setup program. Verify that all USB ports are enabled. See "USB Configuration" on page 43.

If your keyboard is not functioning, you can also use remote access. If the system is not accessible, see "Jumper Settings" on page 123 for instructions on setting the NVRAM_CLR jumper inside your system and restoring the BIOS to the default settings.

7Reconnect and turn on each USB device one at a time.

8If a device causes the same problem, turn off the device, replace the USB cable, and turn on the device.

If the problem persists, replace the device.

If all troubleshooting fails, see "Getting Help" on page 131.
