What to do about USB VID and PID?
As @chrismas9 pointed out to me, there are a few options, none of which are optimal:
- Buy your own VID from USB-IF for $US5000.
- Request free PIDs from Openmoko http://wiki.openmoko.org/wiki/USB_Product_IDs
- Buy PIDs from MCS Electronics for EUR9.95. Their VID has been revoked so they are only selling a guarantee that no one else will have the same PID.
- Use VID=0xf055; see http://hackaday.com/2013/10/22/usb-implementers-forum-says-no-to-open-source/
esp32S3 The USB function is occupied by USB jtag/serial (VID_303A&PID_1001)
Port, board and/or hardware
esp32S3
MicroPython version
MicroPython v1.24.1
Reproduction
No, I've provided everything above.
Expected behaviour
Like 1.19, there is no need to plug or unplug the USB cable, and USB related functions can be used normally
Observed behaviour
on win10
After connecting the USB cable and booting up, the pc system will generate a USB jtag port. After entering micropython, all USBs do not work (such as my microPython USB CDC repl), and the USB jtag port will continue to exist (not work,VID_303A&PID_1001). Only by plugging and unplugging the USB cable once can the relevant USB functions work properly
V1.19 does not have this issue (but on 1.19, IDF's bootloder performs some pin detection to enter different OTA apps. detection stays for >200ms, the same issue will also occur)
Additional Information
No, I've provided everything above.
