I have been asking for over a year for a fix to the current CP210X OS X drivers which will allow sane naming of multiple device names. The seemingly random assignment of a number to the end of the SLAB_USBtoUART device name is causing havoc every time I restart my Mac with two CP210X devices attached.
Other drivers for other devices append something unique to the device, like a serial number, to the device name so that it is not only unique but associated with the same physical component no matter what. Will you folks please look at doing this soon with the CP210X driver?
I've tried the latest VCP driver on my Mac M1 Big Sur and my CP2102 works well. There is only single instance of "CP2102 USB to UART Bridge Controller" in System Report.
Could you tell me more about your Mac and your CP2102 device?
