Hi,
hi folks,
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. Alles anzeigen
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?
I was struggeling with the same issue, but here is how I fixed it a minute ago, at least for now:
Hardware:
WS2801
RasPi 3b with Hyperbian
HDMI2USB Capture Card with Loop (https://de.aliexpress.com/item…042311.0.0.63294c4d3bN53r)
To fix the problem, I found help on this site https://www.pcwelt.de/ratgeber…ry-Pi-selbst-9824929.html (sorry, it is in german)...
In brief, I checked for proper firmware with apt-cache search firmware, providing me with a long list of different peripherals. In this list, I found the firmware hdmi2usb-mode-switch, which I installed via apt-get install hdmi2usb-mode-switch. Having that done, I was able to find my usb streaming card via lsusb etc. and after a reboot also hyperion recognized it as a possible usb input device. Finally, I followed the steps mentioned in the initial post, which brought my ambilight to life.
I hope this solution will work more than 5 minutes...
Cheers
