Thank you for your information.

Nevertheless I have USB-modbus device that needs ch341 kernel module.

 * ch341.c implements a serial port driver for the Winchiphead CH341.

 * The CH341 device can be used to implement an RS232 asynchronous

 * This driver only supports the asynchronous serial interface.

Any suggestion how I can do that ?

Update:
I just saw your references to all the kernel sources and its related patches as general references, but kernel (patched) sources specifically to reproduce the linux kernel used in UR Robots are not available to end users, are they ?
