Hyperhdr doesnt see the USB grabber and I can see it in the ssh screen. So whats going on?

Steps to reproduce

What is expected?

For the system to find the usb graber normally

What is actually happening?

Most of the times it cant find my usb grabber. And in the ssh log I can find the grabber, but in the hyperhdr web interface not.

How can I get this automaticly, because this system will not be for me so I cannot leave it like this.

Hi
1 normally such a message means that the user does not have permissions, but if it works later, it is probably not the case
2 Your SD card/disk is dying which is causing a very slow loading of a key OS module (v4l)
3 You are using a grabber that is causing problems in this module

You can find more in dmesg. This is not a HyperHDR problem and diagnosing it in each specific case is a nightmare (a similar issue comes back once a year, last time it was probably caused by some fake UTV 007): I am not taking up this topic.

Hi, me again I want to inform you about this topic. I have now 3 raspberry pi zero ws running hyper hdr. I have 2 captures. The thing I noticed was that none of the raspberry pis found the 2 grabbers. It did only find it when I disable and enable usb capture. Then it was there. Now I have 1 system running hyperion and It found both instantly. No problems with hyperion. So how can it be my hardware thats the problem. If I need to believe you I have 3 raspberry pi zero`s that will die. And that both of the grabbers are fake. How can It be that hyperion uses it instantly? This means that this is a software issue on yor software. So please reconsider. Maybe the usb grabber scanning needs to be delayed a little time.

Not planned. The main key is to start HyperHDR as soon as possible, without any delay. Similar to shut it down. If some other software takes longer to start-up (and it's actually an unwanted side-effect and not intentional) then maybe it might actually work in your case. You can always delay service start-up by modifying the HyperHDR service file and adding any delay you want.

Service file:
/etc/systemd/system/hyperhdr@.service
add to service section:
ExecStartPre=/bin/sleep 30
Apply changes:
sudo systemctl daemon-reload

Thank you, I will try this :)
