Critical: libusb_init failed

Got this in the Plex docker log. Does anyone have clarification or what needs to be done or how to fix?

That is normal. Is plex working otherwise?

Correct. It states that it did not find a USB based TV tuner. Unless you have one of these, you may ignore it.

Thanks for the help.

I do not have a USB based TV tuner, and no plex is not functioning correctly.

Yesterday the connection was lost maybe three times all day.

Today it is disconnecting every 15 minutes or so.

A LOT.

I am at my wits end. I had gotten to the point where I assumed it was a Win11 issue. But I am no longer sure and don't know how to proceed.

I have followed as mnay of the suggestions I could find and none of the have helped. But it so intermittant.

Now after I open unRaid (which I can do) and I try to open Plex and Sonarr, The address line shows this

about:blank#blocked

What gives?

Make sure you don't have an adblocker or anything else interfering with your browser.

I was able to enter the addresses manually and connected.

How would I search for an adblocker, I have not added one myself, but this is a new computer for MicroCenter and I don'e know what was initially installed.

I haven't seen evidence of one though.

Come to think of it, when I visit a certain website, it always says, "I notice that you are not seeing the ads".

Odd

What browser?

I think you solved it for me. Though I did not think of it as an adblocker, I have Aura installed and it blocks insecure websites.

I unchecked that part and it seems to have worked. I will not count my chickens, but I will now look into making Plex "secure".

Not sure what is involved in that, but that is my next quest (if my good fortune continues with this issue).

Thanks so much-
