I want to connect an OpenMV to a computer that does not have usb-serial drivers. I want it to boot in ‘MSC’ mode. I’ve tried several lines of code but I can’t.  
What line of code should I introduce and with what parameters?

#main.py

import pyb  
pyb.usb\_mode(‘MSC’, msc=‘cam1’)

Hi, while that feature of MicroPython is present on the OpenMV Cam we don’t offer support for it. Not really how the product is to be used.

Also, by default it appears as a mass storage device. You don’t need to modify the code onboard to force it to do that.
