MF Utility bilnks between MF Twister and "No Midifighter Detected"

[bqrk]

I have MF Utility 2.85 on Windows 10. My MF Twister is plugged directly into the computer's USB port.

When I launch MF Utility, it blinks back and forth every second between showing my MF Twister and "No Midifighter Detected"

On the bottom left of the window, it says "Connection closed"

I got the utility to stop flashing by unplugging all my other USB devices.

I am getting the same thing. If I unplug every device on my computer, the MFT utility works. But as soon as I plug something in, even one of my devices, it starts flashing between the screen and "nothing connected?

I have the same issue on mac with the 2.9 version of the software.

Anyone can help?
