Of possible interest is a user's bug report for Rapid Photo Downloader (which uses libgphoto2), which reports a GoPro Hero 7 unmounting problem. To give libgphoto2 access to a camera / MTP device, Rapid Photo Downloader attempts to automatically free the device from GVFS's control (the so-called unmount). It normally works without issue, and libgphoto2 can access the device as expected. But with the GoPro Hero 7, the user reports "running Rapid Photo Downloader when the GoPro is already mounted causes it to unmount/mount repeatedly until RPD is closed or the GoPro is unplugged."
I have not followed up due to lack of time (and a lack of the device) on my part, but the Rapid Photo Downloader log files indicate the user's report is accurate — the system is automatically remounting the GoPro as soon as it is unmounted, which is not something I've seen before. https://bugs.launchpad.net/rapid/+bug/1854623 On Sun, Jan 19, 2020 at 9:53 AM Sasi Karanam <sasiemail2...@gmail.com> wrote: > Still I am getting the same error message.
