SCADAPack 334 - Can't Connect My Device via USB

[Mitzurin]

I've been trying to connect using Telepace, and when I connect via Modbus/USB (I have also tried different cables and different PLCs), I get an error message saying, "The send command operation failed. The USB connection is in use by another application." When I connect via Ethernet, everything works fine, and the USB port on my computer functions correctly with other devices. My operating system is Windows 11. 

I've been researching this issue for a while and haven't found any solution that works so far. I'm starting to believe it might be a compatibility problem with Windows 11.

I greatly appreciate any kind of help.

Hello...

Telepace Studio has not been tested for compatibility with Windows 11. It likely will not be made compatible, as the RTU models it works with are no longer offered. I'd suggest you either run Telepace Studio on a Windows 10 machine or in a Win 10 VM on your Win 11 machine.

I have the same problem and I removed Windows 11 then installed Windows 10. The same problem still valid.

One other thing you might try is to select Modbus/TCP then enter an IP address of 10.2.3.4. That points to the USB port, but uses a different driver. Might not work, but it's quick and easy so might as well try it.  

If that doesn't work, I suggest you contact our global technical support team. You can reach them directly at:
