Hello,
I got two similar webcams, but i tried with 2 different type webcams and it worked fine.
Now when there are two similar webcams, i can connect only one and it's always the same one.
They are quite low quality cams, only 640x480 so bandwith should not be issue, tested with different cameras that both were fhd and that worked fine.
Might this be issue with windows as client, or virtualhere issue?
vlc and other programs say on camera #1 that it ain't good for opening, but for usb camera (withouth #1 on name) opens up most of times without no problem.
