C. Other issue beside power that can be affecting the scanner. 

1. Switch User Function 

The switch user function is a simple and easy way to change Windows users but it can create a ton of issues with devices and PassagePoint licensing. When doing a switch user, devices and licenses can be held by the previous user, when this happens the new user will not be able to log into PassagePoint (no license available) or use certain devices (ie. printer, camera and scanner.) 

When the system or devices lock up because of the Switch User Function, the best solution is to restart the machine, which is not ideal as you'll need to wait for it to reboot. 

Therefore, the “Recommended Best Practice” would be for the new users to make sure they log out of the previous user before logging into their Windows account. 

D. Best Practice For Moving Sign-In Stations & Storing Devices 

1. Labeling USB ports 

The ideal situation would be to have the devices always plugged in but this may not for possible for certain stations, as these stations are going to be moved or left unmanned. Make sure you mark each USB port so that you can plug each device back into the exact same port being used before removing, moving or storing the devices. This is not a 100% fix but it will provide less issues. 

The reason for this is how the integration is done within PassagePoint, when we add the devices into PassagePoint, we tell it where it needs to look to find those devices. This makes it so that you do not have to select the devices when using that specific feature. i.e. scanning ID, printing badges or taking picture, in PassagePoint. The draw back with this is, when you plug the device into a different port PassagePoint may not be able to find it and now you are unable to connect to the devices. 

2. Allow End User Access to Station Preferences
