STM32 programmer compatibility problem with MCP2200 USB to UART bridge

I designed a usb to UART plug in board on which I like to program my board through STM32F302CC's UART1.

If I push the connect button on STm32 Cubeprogrammer IDE(ver 2.1.0) I get the next messages

08:20:49 : Serial Port COM3 is successfully opened.

08:20:49 : Port configuration: parity = even, baudrate = 115200, data-bit = 8, stop-bit = 1.0, flow-control = off

08:20:50 : Activating device: OK

08:20:50 : Chip ID: 0x422

08:20:50 : BootLoader protocol version: 3.1

08:20:50 : Response received from device: NACK

08:20:50 : Error: GETID command not acknowledged!

08:20:50 : Reemission of GetID command

08:20:54 : Timeout error occured while waiting for acknowledgement.

I tried it with FT232R(FTDICHIP) USB /UART bridge, it works fine

I tried the older STMFlashLoader_demo.exe ver 2.9 RC4 with MCP2200 USB/UART bridge, but I got the same result

Have you got any solution for MCP2200? I did't find any info about what kind of USB /UART bridge supported by STM32 Cubeprogrammer.

I use 64 bit win7

Thanks in advance

Did you resolve this issue?

Doing something odd. You'd need to use a scope or logic analyzer to determine what with the nature of the signalling is wrong.

Not much point in guessing.

I have the same error with STM32L010F4P & MCP2200 & STM32CubeProgrammer 2.4.0
