NCE has identified the following issue regarding using the USB interface with a SB3, SB3a or SB5.
Some users may experience a communication loss to the USB interface or AIU after resetting the command station to factory settings. They lose the ability to use certain cab addresses for the USB interface, AIU and other cab bus items.
This has been fixed by a firmware update version 1.65B for the Smartbooster.
This patch does NOT affect the Powercab.
