KB01589 - AT-UHD-HDVS-300-KIT - RX USB Hub not detected after reboot



Challenge: The RX USB Hub is not detected by device manager after a reboot of the computer.


Troubleshooting: Toggling the USB input or removing the USB host cable and plugging it back in should allow the computer to show the RX USB hub.



If these BIOS settings have been modified from their default settings

Change BIOS POST setting: FastBoot from Minimal to Thorough

If the above does not correct the issue, then "Extend BIOS POST Time” to a non-zero value, or disable fast startup. Fast startup can be found in Windows Control Panel @ Control Panel\All Control Panel Items\Power Options\System Settings
