Many desktops of recent vintage don’t truly go ‘off’ at shutdown.  There are 
mobo elements still powered (by the p/s), including USB. 

To reset a ‘stuck bit’ the power cord must be unplugged then wait a time period 
until the caps STILL holding power deplete (a LED on my Asus board goes out and 
a soft relay click is heard).  Only then does the USB reset and starts to 
function normally at boot up. 

My current station setup is not ideal, the USB is the weak link under QRO HF.  
I’m in the process of building a better quality station.
