H7 Plus Appears in Device Mgr But Not Connecting to IDE

OpenMV Products

Not able to get my H7 Plus to connect to the IDE.

Knowns:
-It flashes blue as if running the python script.
-It appears in Device Mgr (and Windows) as a storage device.
-It was working the last time I tried it, probably a year ago.
-Running the latest IDE version 4.4.7 on Win10.

What I tried:
-Changing the cable didn’t fix it.
-Uninstalling/installing older IDE versions didn’t fix it (3.0.3 and 4.0.1; back to 4.4.7 now).
-Running the “Is it bricked”>reconnect with RST & BOOT jumper process failed (continuous error message in the popup details
-Trying to connect now and it says a board in DFU mode was detected. I tried installing latest (4.5.9) with erase internal file system unchecked and it said it was successful. I then removed the jumpers, disconnected/reconnected the board as instructed, and the green LED keeps blinking while the IDE still said “Reconnect your OpenMV Cam.” I hit Cancel after 10-12 min. which brings me back to the “is it bricked” question.

It does not appear in Device manager anymore. Here is the detail popup for flashing:

Any obvious things to try?

On a side note: Is there a place to find specific firmware versions? I couldn’t find them on the github site.

I did try the new firmware option and said yes to erasing internal file system, and now I got it back to blue flashing lights and appearing in Device Mgr (& Windows) again, but it just won’t connect to the IDE. Maybe it’s a driver issue? Are there correct OpenMV drivers available to try?

Hi, you might have something breaking the COM port.

The USB Device will appear as a COM port and a USB Mass Storage Drive.

You should see this when the camera is plugged in:

I see no COM ports in your device manager where they should appear.

Our driver installer under windows would have set everything up correctly. However, if there’s a third party driver on your system that’s affecting the thing you’ll need to find the base USB device and uninstall the conflicting driver… By default, we actually don’t install any drivers for the COM port or USB Storage anymore as these ship with windows now days. We only install DFU drivers for updating firmware.

Note, about the disk drive, you should see this also:

Assuming that’s present then USB is working and the camera is fine. The issue is then just a driver issue on your PC.
