Logical device number changes after cycling power on system

Product: TDT Drivers
Version: <= 46

Issue
Each time you cycle the power on the system it changes the position of the zBUS racks with logical devices. Closing RPvdsEx and other programs before cycling power may help to avoid this problem.
Workaround
Reboot the system.
