The CP210x has a EEPROM on the chip which can be programmed via USB. The CP210x is an USB-to-serial chip used in a lot of USB devices (similar to FTDIs and PL2303). I've read the following thread from this forum about being able to reprogram the EEPROM - /thread62529.html - however for adaptor 1 if I leave the eeprom writer program settings as default, change the serial number or the PID and press write, I get an error message 'Compare EEPROM failed!' I've compared the devices in Windows Device Manager, and also with 'lsusb -v' in linux and there's little to distinguish between them. If serial device X is connected to adaptor X and serial device Y connected to adaptor Y, when in linux the kernel can detect an assign these USB devices different device names between reboots. I would like to be able to identify them through software without having to know which adaptor is plugged into which USB bus or whatever. Here's the problem - I have two USB to serial adaptors (identified as using the Prolific PL-2303) which *aren't* identical in appearance but appear the same when detected by OS's.
