Troubleshooting a USB device

Prerequisites

NOTE: Follow steps 1 to 5 to troubleshoot a USB keyboard or mouse. For other USB devices, go to

step 6.

Steps

Disconnect the keyboard and/or mouse cables from the system and reconnect them.

If the problem persists, connect the keyboard and/or mouse to another USB port on the system.

If the problem is resolved, restart the system, enter System Setup, and check if the non-functioning

USB ports are enabled.

In iDRAC Settings Utility, ensure that USB Management Port Mode is configured as Automatic or

Standard OS Use.

If the problem is not resolved, replace the keyboard and/or mouse with a known working keyboard

or mouse.

If the problem is not resolved, proceed to step 6 to troubleshoot other USB devices attached to the

system.

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

Restart the system.

If your keyboard is functioning, enter System Setup, verify that all USB ports are enabled on the

Integrated Devices screen. If your keyboard is not functioning, use remote access to enable or

disable the USB options.

If the system is not accessible, reset the NVRAM_CLR jumper inside your system and restore the

BIOS to the default settings. See the System board jumper setting section

10. In the IDRAC Settings Utility, ensure that USB Management Port Mode is configured as Automatic

or Standard OS Use.

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

12. If a USB device causes the same problem, turn off the device, replace the USB cable with a known

good cable, and turn on the device.

Next steps

If all troubleshooting fails, see the Getting help section.
