Usb web camera failing while in use

sh flag
gone

I have had a Logitech c920 that has worked fine for a long time. Recently, after a routine upgrade I started seeing failures during video calls where the camera would darken, flicker and finally drop from the detected hardware.

I've tried upgrading my kernel:

$ uname -a

but no good - a complete cycle of plugging the camera directly into the laptop to failure:

I think the issue might stem from [ +0.000349] gspca_vc032x: reg_r err -32 but I can't find any information on this - any ideas?

Intermittent USB connector/ cable / other connector fault? Try other USB ports, a different cable. Try a powered USB Hub.

I've tried different ports/powered hub - I think at this point the only only cable I haven't changed out is the one built into the camera. Do you think it's possibly a broken camera?

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.
