[Elecraft] COM port problems

[Fred Jensen]

Peter:

1.  Open Control Panel and click on Hardware/Sound-->Device Mangler-->Ports

2.  In the View menu, click on Show Hidden Devices

If there are any, they will appear in the Ports display but grayed out.  
Delete them, close everything, reboot, and try again.  Windows will 
occasionally, and without notice, leave a previous device enumerated 
even after it is removed.  It shows up as unavailable, or in-use to a 
real device.

May not be your problem, but an easy fix.  Best to remove all USB cables 
before the reboot, then insert them one at a time while watching the 
Ports display
