I need to use Mobius 1 Action cameras in a project.
When I connect these cameras to VLC or guvcview they play correctly
for about 10 seconds and then freeze. They work properly in Windows
11.
How do I troubleshoot this issue or get someone from the appropriate
community to help me ?
Thanks

Run "sudo journalctl -fa" in a terminal window and see if anything shows
up when the problem occurs.

Thanks for the reply.
Here is the output when it fails. The "Unable to dequeue buffer: no

There should have been some USB message before that started.

It's resetting for some reason. Here it reconnects.

That's interesting and might be relevant.
Find the log lines before the dequeue errors start to see what happened.

Unless you keep unplugging it, it appears to be having a problem. Are
you using it with windows on this same computer on the same port?

Not with this log I'm not. But my laptop dual boots F36 and Windows
10. F36 freezes just like on this computer. Windows 10 runs it fine.

Sorry, I don't have any more suggestions. The camera is disconnecting
for some reason and I don't have any idea why that might be.

Is the computer powering other things via its USB ports?
Inadequate power is one potential cause for USB disconnects. I'm not
sure if the USB power negotiation is done entirely in the hardware, or
if the OS has a say in the matter.
Discounting that potential cause, how many USB things are plugged in at
once? There could be some hardware conflict with the Linux drivers.
Or it could just be Windows-only, some quirk in the device that they
dealt with by a special tweak to the Windows driver.

It is connected straight to a USB 2 port on the computer or the
laptop, depending on which I am using for testing. No other devices
are connected.

at
once? There could be some hardware conflict with the Linux drivers.
And where do I go to get help troubleshooting that ?
