We use SpaceNavigator with Virtual PC technology based on the VDI product from Citrix, XenDesktop 5.6, on which we installed Inventor 2013. The SpaceNavigator is connected to a PC and is used as a thin client to connect to a virtual PC and everything is connected with the Citrix HDX protocol. Its looks like terminal server except that it's Windows 7 nativ.
SpaceNavigator usually connects properly and can be used normaly in Inventor.
But occasionally and randomly 3D mouse disconnects and lose the connection (4-5 times per day). It seems that the problem come from the network, and we've been able to improve the situation by playing on the protocol priority. Prioritize channel that transmits information from the USB port redirection. See http://support.citrix.com/article/CTX128190
Do you have an idea about this disconnection problem?
Is there a setting that increase the timeout to the USB port?
