finally got my card to work - it was indeed an issue with the cable. tried every single cable that i could find and eventually the device was recognized. after some tinkering with the settings everything works now. thanks for the help!
thanks for the suggestion. i didn't have /dev/video0, but i had /dev/video10-16, i tried capturing using each one of them, but no luck
Thanks a lot for a quick response, appreciate it! I tried as you suggested, i.e. increased the usb power and upgraded, but the result is the same. i'm wondering whether this could be a cable issue, at least something should be showing up in dmesg when i plug it in, right?
i also got one of the devices as in the picture in the first post, and i'm struggling to get it to work on rpi0. when i plug it in, nothing shows up in lsusb, dmesg; here is the output from v4l2-ctl:Code
$ v4l2-ctl --list-devices bcm2835-codec-decode (platform:bcm2835-codec): /dev/video10 /dev/video11 /dev/video12 bcm2835-isp (platform:bcm2835-isp): /dev/video13 /dev/video14 /dev/video15 /dev/video16 Cannot open device /dev/video0, exiting.
So it doesn't seem to be recognized. Same behavior when i plug it in to my laptop running ubuntu 20.04. i've also tried a windows box, and there i have no issues - everything works like a charm, so i'm confident that the device itself is working properly.
Any suggestions how to get it to run on Linux, or is there no hope?
