esp32 S3 USB "bug"

Postby chegewara » Sun Nov 14, 2021 1:01 pm

Is there any plan to "fix" esp32 S3 USB in rom to have different PID for S3 than C3. At the moment i believe they have exactly the same VID and PID, which may be at least confusing.

You mean the PID of the USB-JTAG-serial adapter? That's done on purpose; it's the same peripheral, and what core is behind it is variable up to the point that in the future we'll allow chips to be used as a standalone USB-serial-JTAG adapter that you can connect to whatever.

Yes, thats what i mean.

I can accept that, but to me its a bit odd, because for example different CP210x models have different PIDs.
I am asking about different PIDs, because for now arduino IDE displays esp32 S3 as C3, but like i said, i can accept that explanation:
