Left Side USB 3.0 Port Will Not Recognize USB 3.0 Devices

When a USB 3.0 device is plugged into the left side port, it is not recognized as a USB 3.0 device and will run at USB 2.0 speeds.

See the User Guide for more information.

Disable USB Debug

This behavior is by design.

When shipped from the factory, the left USB port is configured in the USB Debug mode in the Basic Input/Output System (BIOS or System Setup) to allow the ability to boot to a USB drive in the left port. (BIOS Default Setting.)

If USB 3.0 speed are desired in the left port, then boot to the BIOS (Press F2 at boot) (See Figures 1 & 2 Below):

  1. Click the Advanced Tab
  2. Double-click Miscellaneous Devices
  3. Click USB Debug and select DISABLED
  4. Press F10 to save and exit, highlight Yes with the arrow key and press enter to save and exit
