Constant stream of message boxes with "Unable to mount MTP device" plugging in GoPro HERO 7

[Jeffrey Walton]

Hi Everyone,

I am using Ubuntu 20.04.3 LTS, x86_64, fully patched. I installed Cinnamon and got rid of GNOME because I needed a tiling window manager. The File Manager used with Cinnamon is Nemo.

I bought a GoPro HERO 7 and plugged it in over USB to charge the battery. The result is a constant stream of message boxes that states:

    Unable to mount HERO7
    Unable to open MTP device "xxx,yyy"

In the message, xxx appear to always be 001. yyy changes, and takes the values 001, 002, 003, 004, ...

A new message box appears approximately every 10 seconds.

I think one message box will do just fine. There's no need to spam me every 10 seconds.

My apologies if this is not a Nemo issue. Looking at the message box, it is the sort of thing provided by the file manager.

it looks like the yyy values loop at 128. So the range is [001, 002, ..., 126, 127]. After 127 the value loops back around to 001.
