### USB Ports Become Disabled (6424279)

USB ports might become disabled during operation. This appears to be a hardware problem related to the NVIDIA USB controller.

When this happens, the device attached to the USB port becomes inactive. A message similar to the following is reported in the file:

    [ID 691482 kern.warning] WARNING: /pci@0,0/pci108e,cb84@2 (ohci0): Connecting device on port 1 failed

## Workaround

- Reboot the server to re-enable the USB ports.
