Firmware 2.1.4 of CP341 solved the problems you are talking about.

Unfortunately the patch DID NOT fix the board lockup. Even firmware release 2.1.5 does not solve the problem.

I have many (20+) PLC installation that have experienced the problem.

On site (not on a test lab) even when all is working fine, if you disconnect one wire in the half duplex RS485 trasmission line (creating noises) the CP341 locks up in matter of seconds.....

I also opened a support ticket but was unable to find a solution

Definitely buggy.

 Hello

A similar problem( FW V2.1.6) no transmit( no ERROR or/and DONE signal. Diagnostic buffer OK)

There was a solution?
