Unknown USB Device


I recently received two OpenMV H7 units and have been unable to update them. Upon the initial connection, I was prompted to update the hardware’s software. This failed and now my computer won’t recognize the cameras any more, only showing a Device Descriptor Request Failed in the device manager.

I’m trying to proceed through the bricked unit prompts, but it’s just stuck on reprogramming.


I was able to get into DFU mode with a few restarts. All is well now!!

Great to hear!
