Interchangeably using the QS20H-I-U and CU-8021

I want to use the QS20H-I-U and CU-8021 interchangeably on the same USB port, as they are using the same driver. Is there any instruction or suggestion?

You should observe the following notes when using them interchangeably on the same USB port.

  •   ・If either one of the QS20H-I-U or CU-8021 is already installed, the other one does not need to be installed.
  •   ・The same COM port number is used in these two
