Multiple usb video feeds

[Beanster]

How many usb video feeds can you have in OBS ? I have two GoPro hero 4 silver cameras and I can’t seem to hook up the second one. Using a micro usb c cable to hdmi cable and then hooking that to a video capture card to a standard usb cable on both cameras.

You can use any number, as long as you manage to provide enough USB bandwidth for all your feeds at the same time. This requires distributing your devices across all available controllers and internal hubs of your computer. Multiple USB 2 capture devices at the same USB hub might result in bandwidth issues.

To see the hub tree structure and which device is plugged into which hub together with other devices, and with which speed a device is actually operating, a tool like usbtreeview is extremely helpful: https://www.uwe-sieber.de/usbtreeview_e.html
