I have a problem with connecting my Trust Webcam via an OTG hub to my Raspberry Pi Zero 2 W.
So, I have a problem with connecting my Trust Webcam via an OTG hub to my Raspberry Pi Zero 2 W. When I connect the webcam to the hub, it shows up, but I can't use it. However, when I connect the webcam directly to the Raspberry Pi using just a normal OTG cable, then it works fine. Does anyone have an idea on how to still use the webcam through the OTG hub? Because I also want to connect my 3D printer at the same time!

hi , i think u should do external power supply
Thanks for your message, but it's not a power issue. I already measured it, and everything seems fine.
And i even have a extra power source going in so i dont think thats the problem
so what kind of otg hub are you using ... is it externally powered .. ? like i saw many people have reported similar issue and they got their usb devices recognised via using a powered hub .. so you may check that ,...
Its 5.1v i measured it so its not a power issue i think
okaayy ... but whats the hub you are using .. share its name and ... voltage obviously would not the issue as core ..
