Help! I am a new user and can’t get more than two of my Microsoft Q2F-00013 USB 2.0 LifeCams to show up at a time. I have 11 on my system and if I unplug one a different one will show up. I can’t figure out what I’m doing wrong. Is there somebody who can help me. We have verified everything from installing the software to rebooting the system to verifying with the actual computer that all of the cameras are showing up but when we are in blue Iris we cannot get them to show up and we get error messages

Thanks in advance
