Hi all

I have a TXT which(frimware 4.2.3.0) i have to test but it won't connect to my W10 PC.

So i did take my own TXT(firmware 4.4.4.0) and that one also does not connect any more.

Only thing that it says is "(Error) Opening USB port"


But my old Robo Interface/TX/Robo LT old/ LT Control USB Power/ does work fine.


Robo-Pro version 4.6.6

What is going wrong?

With RoboPro 4.6.6 the firmware on the TXT needs to be 4.6.6 or 4.7.0 or 4.80.

My own is updated to the newest firmware but the USB does not work.
Other interfaces all work even the older Knobloch's i have with the connect box, so all 20 interfaces work only the TXT does not work on the USB port with Robopro.
I have 8 USB ports on my PC and all give the same error.
I can use it whit Wifi but that gives sometimes a conflict whit my second PC.
Bluetooth does also not work.

The other TXT did crash by the frimware update and does not work any more so that is a problem i can not solve and has to go to the Dutch importer.
This one is of the fischertecnhikclub Nederland.

Frimware update was done on my other pc there the USb does work on both TXT's, and an old Robopro version to update the old firmware TXT.
But after 2 hours i did stop it because it was already hanging for that time on the same line, and did not shut off.
When it is start it stops in the middle of installing the program and hangs for ages without ever going to work.
