[Elecraft] Missing first piece of dash or dot when sending CW with K3S USB input with Wintest.

[Brian Hunt]

It's possible that Windows 10 is powering down the hub that the device 
is connected to.  In the Windows 10 Settings dialog click on devices and 
scroll all the way down to the bottom and select Device Manager.   Then 
click on USB controllers to open and view all the hubs.  Double click on 
each hub and select the Power Management tab and then uncheck the box 
that allows the computer to turn off the device to save power.  See if 
that helps.

Also make sure that Windows Sounds are off.  This is because Windows may 
stop all I/O including USB when it's doing a sound.  (Or at least that's 
what I've heard).

Good Luck!
