Raj,
Try looking in Device Manager again. Which COM port goes away when you
unplug the USB cable from the computer? COM1 is normally reserved for
the motherboard serial port - which will be RS-232 and not USB. It will
be there whether it is connected to the back panel or not.
Then plug the USB cable back in - which COM port is assigned? Put that
COM port number into K3 Utility and try to connect.

Hello,
I have KIO3B (USB interface) in my K3. It was working well. Single
USB for audio, and CAT.
Suddenly, now the CAT part is not working. Here are some aspects:
* RS232 in K3/Config shows USB
* Serial port 1 shows up in device manager on the windows computer when
the USB is plugged in. The sound codecs are working.
* Nothing communicates with the K3 CAT any more (K3 utility, and logging
programs do not see the K3 on the com1.)
* I tried it on a new laptop with a fresh USB cable. Exactly the same
issue.
