Hi there. I’ve gotten the my capture card to work before. But it will continually disconnect and reconnect and has been giving me grief ever since install. The card should not need drivers as it acts as a USB Webcam.
Occasionally the card will work, but for the most part it just flickers in and out of existence.
Is there any information I should include?
Welcome to Manjaro!
Please read this:
How to provide good information
and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies… 
An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
The output of:
journalctl --system --boot=0 --priority=3 | tail --lines=35
ASAP after the card starts flickering would be helpful as well. (E.G Insert it and then run the above)

Have you tried the latest LTS kernel yet? (5.10)
You’ve got it to work before? Because it doesn’t get recognized as a specific capture card under 5.13. Is it one of these?
Some program is polluting your journal file: I need the last 35 lines without any of these:
Check the tlp settings for it or disable tlp …
I had the same issue on Debian and what helped me was to disable USB autosuspend. I suspected the kernel did not know what to do with the capture card if it was not used by some recording software as pointed out in a couple of Reddit threads.

I also found a question on[ StackExchange](unix.stackexchange com/questions/91027/how-to-disable-usb-autosuspend-on-kernel-3-7-10-or-above) which helped me disable USB autosuspend on Debian but there are generic instructions too.
From StackExchange:
For Ubuntu and Debian,usbcoreis compiled in to the kernel, so creating entries in/etc/modprobe.dwill NOT work. Instead, we need to change the kernel boot parameters.
Edit the/etc/default/grubfile and change theGRUB_CMDLINE_LINUX_DEFAULTline to add theusbcore.autosuspend=-1option:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"Note that
quiet splashwere already present options. So keep other options you have too.
After saving the file, update grub:sudo update-grubAnd reboot.
Please let me know if this was helpful.
