hello, I have a elegoo neptune 4 with crowsnest and got one webcam working with it. Since the neptune 4 only has one usable usb port, I connected both webcams through a usb hub (tried two different ones but same result) and change the config to by-path but only one webcam at a time is giving a output (the one that started first) Am I doing something wrong or are usb hubs not supported?
#second webcam with no signal on usb hub

Send the output of ls /dev/v4l/by-path
Also set log_level: debug inside your crowsnest.conf and send a new log

ERROR [11591.049 stream] -- Unable to start capturing: No space left on device
This indicates an USB bandwidth limit
So most likely the thing inside neptune 4 isn't capable of 2 1280x720@30fos streams
Try to lower fps, if that doesn't help the resolution too.
Might work then, but don't have to

even with the lowest settings it wont work and the error message comes up
