[Elecraft] Problems with HRD, Windows 7 and the old Serial converter cable using the PROLIFIC chip set

[Robert Redmon]

I have a similar problem with my "old" Prolific chip based usb/serial 
cable. It worked fine on my XP computer. The driver loads without issue 
on my new Windows 7 computer and creates a virtual serial port and 
recognizes and installs the adapter when I plug it in,  but in my case, 
I am unable to connect to the K3 utility (haven't tried anything else). 
I have not been able to resolve the issue with the latest drivers from 
Prolific or from the driver on the Elecraft download page. I have been 
using an old XP laptop to configure and do firmware upgrades.
