Administrative rights requirement for use of VDM USB Driver

USB redirection requires administrative privileges on both client and desktop virtual machines. If the user does not have the necessary privileges in both places, the USB device redirection functionality will be unavailable.

For Windows Vista clients with User Access Control enabled (the default), to run VDM Client with administrative privileges, follow the instructions in Microsoft KB 922708 on how to run a program as an administrator:

For Windows Vista guests, disable User Account Control so that VDM Agent components run with administrative rights (running the wssm.exe process as an administrator is not sufficient, as Windows Defender will block this process running with administrative rights at startup when UAC is enabled).
