Your camera device in the probe is:

PCI 8086:1919:103c:82ca / 04-80 Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Imaging Unit multimedia controller ipu3_imgu

Looks like this device is not yet supported by Ubuntu (work in progress). But I see people solved the issue with one of the cameras on the ChromeOS fork: https://github.com/sebanc/brunch/issues/1027

Try it on your tablet instead of Ubuntu: https://github.com/sebanc/brunch

Next time check the tablet Linux-compatibility before buying. There are a lot of unsupported devices in Linux. Some of them (significant part) will never be supported.

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.
