========================
I had a Windows 7 laptop that ran my station perfectly for years. Then one
day it would not send CW to my K3. I tried new cables, new drivers, new CW
software, etc. etc. I figured that the USB hardware had failed. But one of
my kids is an MSEE in charge of a huge network of servers and clients, and
he said that it was probably a Windows update that had hosed something in
the USB control chain. So I upgraded to Win 8.1, and sure enough,
everything came back to life.

So maybe the same thing happened in your case -- you had a combination of
hardware and drivers that somehow wouldn't play with some update that came
since the last time you tried it. Anyway, you're up and running, which is
the important thing.
