In rare cases, a USB device disconnects itself before Fusion can recognize it.
Problem
When you plug in a USB device, the Fusion EasyConnect dialog box appears, but disappears before you have an opportunity to take an action. The USB device is then not visible to either your Mac or your virtual machine.
Cause
Some USB devices disconnect very quickly if they do not receive an immediate response upon connection. Occasionally, Fusion USB EasyConnect does not produce a response in the time required by these USB devices.
To work around this problem, you must configure the virtual machine so that Fusion connects unknown devices without first having to ask about the type of connection.
