Static MJPEG example on M1S Dock

[marcpabst]

Hi, I'm trying to run the UVC static MJPEG example on my device. It compiles and flashes fine, and both Windows and macOS recognize the camera seemingly correctly. However, I never get an image transferred. Here is the log from the serial monitor:

Any suggestions?

I'll give it another try later! I'm compiling under darwin/arm64, do you think that could make a difference? (just spitballing here...)
