[Elecraft] K3S USB issue with Dell OptiPlex 745 - Win 10

This is an easy one.  The USB ports are going to sleep.  This can be fixed in device manager. 
Google "prevent USB ports from going to sleep".

Our club’s new K3S will not stay connected and often can not be found by our Dell Optiplex 745 w/Windows 10 (it’s an older computer – but seems to run all of our Ham programs and attached devices  without issue).   Reconnecting the USB cables sometimes fixes the issue.   Oddly, if we install & remove a USB mouse to the same USB port and then reconnect the K3S, the computer finds the K3S without issue.    Cycling the computer and radio does not address the problem.  

The K3S connects instantly  on newer Dell laptops and and Apple computers.

There seems to be a driver issue with the Dell Optiplex, but all drivers are current.  We are stumped.

Any suggestions?

Thanks,

Marty – N1VH
