For a friend I try to help with his setup.
PC is Windows 10, 64-bit and the Station is a Elecraft K3. The connection between PC and K3 is an USB cable in both ends.
We guess that a Windows update lost the driver between the K3 and the PC. When the USB is unplugged the error in device manager disappeard.
Does anyone know where to download a new driver for the K3 USB connection to Windows 10, 64-bit?
