usb_stream: ID 0c45:6366 Microdia Webcam support (AEGHB-66) #250

Closed Draghtnod closed 1 year ago

Draghtnod commented 1 year ago

I am trying to get this Webcam working. It seems to be 'smart' and outputs a different Configuration Descriptor on the PC than on the ESP. Unfortunately, only 2 uncompressed formats are supported in this "comparibility" mode. Does maybe someone have a hint, how this "compatibility" mode is triggered?

Check usb_stream.c here. The Descriptors are read right after reset and some basic usb port configuration.

@Draghtnod That's because the camera vendors usually provide different configurations for USB Fullspeed and Highspeed, ESP32S3 supports only Fullspeed mode, so the descriptor for this mode is printed.

The descriptors got on PC are Highspeed configs. To get Fullspeed descriptors from PC, you can add a USB Fullspeed isolator before USB interface, force it not work in Highspeed mode.

@leeebo Thank you, this explains a lot. I guess my only option then is to buy a different camera. :(
