I am attempting to connect two webcams (Logitech C-920 & C-922) to my Dell XPS13 (i7 Win-10) laptop via USB to record music practice sessions via OBS Studio. This machine only has two USB-A ports (one USB-C); I need access to at least three USB-A ports (2 cameras + an audio interface). Therefore, I would like to connect the webcams to a 4-port USB hub. However, when doing so I am only able to view one camera at time; the other remains blank.

I disabled the laptop’s onboard camera thinking this may help but still only one camera at a time. If I plug one camera into the hub and one directly into a port on the laptop it works fine. If I plug both cameras directly into USB ports on the laptop it also works fine.

I purchased two 4-port externally powered USB hubs – USB-A to USB-A and USB-C to USB-A. Both of them only displayed one webcam at a time. I could not view both simultaneously.

In the past the 4-port hub worked fine with my old Win-7 i5 HP Pavilion laptop. I suspected a newer, faster, more powerful, etc. machine would have worked better not worse. I have read elsewhere where some have had as many as six webcams running simultaneously. I understand trying to connect numerous webcams could be a problem but I would think simply hooking up two to a newer computer would not be an issue.

Any suggestions would be appreciated.

I got a hold of my sister’s HP Envy x360. I connected the USB hubs (USB-A & USB-C) to the HP – both of them worked fine. So apparently it may be an issue specific to my Dell XPS13 laptop.

Like I have noted, I am not the most tech-savvy guy around. But, since my machine is only an 11-inch laptop and the others were 15-inch units. Could this have something to do with the size of the laptop? I know that sounds weird but I assume my smaller machine has a smaller motherboard. I’ve read that there may be concerns where different USB ports are connected different USN controllers (or something like that). Does my small unit only have one controller and the larger units have two controllers?

Please bear with me as I am only grasping at straws here so please. Again, any suggestions are greatly appreciated,
Steve K.

UPDATE -
Thanks everyone for your suggestions. I cut to the chase and did a complete Win10 reinstall. What a pain but all is working fine now. So apparently it was some OS setting or possibly a driver that was causing the problem. Oh well, I'm back in business.

Thanks again,
Steve K.
