To resolve this. First remove the ch341 module and replace it with one build locally from source provided by the manufacturer.

sudo rmmod ch341
sudo mv /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko~

Then download the driver source from here.

Unzip it and compile the kernel module locally and install it.

cd ~/CH341SER_LINUX
sudo make
sudo mv ch34x.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial
sudo depmod -a
