[Elecraft] Vista 64 USB drivers

[John Glascock]

I had a similar situation with my MacBook Pro running OS X and Vista Bus.
with Parallels.  I tried the KUSB but could not get the K3 Utility to see
the K3 with either Operating System.  I purchased the Radio Shack USB to
Serial adapter and all work well on both the Mac side and the Vista side
until I rebooted the system.

Now the Mac side works great but when I go the the Vista side Parallels
tells me the USB device is already in use.  I have yet to figure out how to
release the port in Mac so that Vista can see the USB connection.

73,

John, NOIB
K3 #364
