Webcam and Headset plugged into the same Hub cause one or the other to stop

tn flag

I'm on 20.04 and was hoping to get a workstation working. I am using a powered 4-Port USB Hub which I used on Windows to power a USB to Ethernet Adapter, my USB Dongle that connects to my Wireless Headset (Plantronics) and a USB Webcam (noname).

Plugged into the same, either the Webcam or the Headset cease working completely. Only after unplugging one or the other do I get a response again. The Webcam is also still recognized as plugged in, it simply does not react anymore. Same with the headset.

Plugging them into separate USB ports (one in the hub, one directly in the laptop) seems to solve this issue.

Can there be some explanation on why the Hub ceases functionality in this specific scenario? One other wireless headset (SteelSeries Arctis) did work from the same hub together with the Webcam without a problem, it seems to be this specific device causing issues.

There are other devices in the list you show here not in the question. Logitech, Inc. Unifying Receiver

In scenario 1, the Unifying Receiver is plugged into a completely different port going from the Laptop, in scenario 2, because I only have this one hub, I moved the Headset Receiver to the port the Unifying Receiver was in, and put the Unifying Receiver into the Hub. Removing or Adding that Receiver does not change anything about the scenario, though.

My situation was also in two different ports not a hub and the Bluetooth caused problems. Any way good luck I do think you have a hardware conflict not directly a Ubuntu problem.

Thanks, curious because I was of the opinion it might be a power delivery issue altogether. Seems like I will have to look for alternate routes for now.

Watch `sudo journalctl --follow` as you plug and unplug

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.
