USB hub with two cameras, OBS only shows one at a time

New to OBS, so I apologize if I am doing something wrong.

I have a web cam and a doc cam. They are both plugged into a USB hub. (Maybe it is called a replicator, or extender? My laptop does not have many USB slots and this device plugs into one on my laptop and gives me seven.) I started OBS and added the webcam and the doc cam, and the menu system finds them just fine. But if I start OBS and the web cam is showing then unclicking on its "eye" icon and clicking on the other continues to show the web cam. Same for the doc cam. It will show one or the other, never both, depending on which is the staring one. If I plug directly into the USB port then it works great, but I only have the one port.

The permissions of the two are the same.

Code:
jim@millstone:~$ ls -l /dev/v4l/by-id/

Both cameras show fine, just not at the same time. Thanks for any help.
