Miniprog 4 no UART connection after firmware update

Hi,

after updating the Programmer App it asked for updating the MiniProg 4 firmware.

I made the mistake to agree.

Now, I'm no longer able to connect to the serial port of the MiniProg.

All i get is a "OpenPort::Baudrate: Value of 9600 is not supported"

For every Baudrate I try!

Firmware is: 2.21.1005

Windows 10 driver is: 2.0.0.4

Any chance to revert to the old firmware?

I downgraded to firmware 2.10.878 with the Github firmware loader.

And the Programmer 3.29.0.

UART connection works again.
