Webcam failing : mtp-ptobe and colord-sane issue

bw flag

Not sure whats going on here. This is ubuntu 22.04. Suddenly after a reboot (which installed patches) the video devices fail, most notably the logitech webcam. What I see for it in syslog is

Apr 23 20:45:02 orac kernel: [22230.498881] usb 3-6.2: New USB device strings: Mfr=0, Product=2, SerialNumber=1

Apr 23 20:45:02 orac colord-sane: io/hpmud/musb.c 2101: Invalid usb_open: Permission denied

I think it must be the mtp-probe, maybe something about udev rules, but I also wonder about the colord-sane.

Any help?

turns out the mtp-probe is normal, the colord message went away on a reboot, but still the permission faillure. Ultimately I gave up and upgraded to 23.04 which I was going to do soon anyway. Now its working properly.

As in my comment: It turns out the mtp-probe is normal, the colord message went away on a reboot, but still the permission failure. Ultimately I gave up and upgraded to 23.04 which I was going to do soon anyway. Now its working properly.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
