Z690M Aorus Elite AX DDR4 - random USB disconnects

Z690M Aorus Elite AX DDR4 - random USB disconnects
« on: February 01, 2023, 11:47:01 pm »
This system was custom built by online computer store in April 2022.  Since that time I get random USB external drive disconnects.  Event log reports UASPStore 129 events (1-2) and a burst of 153 events.  Outside of these random events the drives and enclosures work fine. 

System is running Win 11 22H2 - 22621.1105.  CHKDSK does not report any errors on the external drives.

SFC and DISM are clean.  High performance power settings are in place, USB selective suspend is disabled, PCI Express Link State Power Management is OFF, turn off hard disk after 1000 is set.

In computer management Universal Serial Bus controllers all items have "allow the computer to turn off this device to save power" disabled.

It is a really annoying problem and I am at a loss to know how to fix it as it cannot be reproduced!

Any suggestions please?
