Is there any way to customize a large number of CP210x devices under Windows without assigning a COM port to each device?
Adding the lines:
[Manufacturing Ignore Serial Numbers] Ignore Serial Numbers
to the setup.ini file will allow the driver to ignore serial numbers, and effectively re-use the same COM port. A COM port will be assigned based on the USB port instead of the serial string. This is beneficial in a manufacturing environment. Before installing the modified driver, any existing driver for that VID/PID combination needs to be first uninstalled using the Control Panel 'Add or Remove Programs' entry titled '...(Driver Removal)'.
