Plugged in my OpenMV Cam H7 Plus today (not new; have used several times). It flashes green 7 times, then white once, waits 2 seconds and then flashes red 3x, and stops flashing. Will not connect in IDE.
Steps so far: IDE asked if it was bricked,I said yes, did the disconnect/reconnect step (it would not leave that step on its own so I hit cancel to skip to DFU programming), disconnected H7, added jumper from RST to BOOT, reconnected, and waited. Device Mgr shows an unknown USB device (which is this) instead of a COM device. DFU device does not appear like it did in this other OpenMV post: https://tinyurl.com/y9mnkxag.
I also tried being impatient and not waiting for it to enumerate; and it timed out after 300 sec of not connecting.
Also tried other USB ports; same issue except some don’t recognize hardware change at all.
Anything else I should try? TIA
