Starting with version 4.35 the USB Protocol Suite introduces Drive Emulation. The AddDrive
instruction allows to emulate a BOT (and later UASP) drive. When connected to a system, the
Trainer comes up then as an uninitialized drive. It has to be initialized and formatted, then files
can be copied to it / from it as long as the Voyager system stays powered up. During this the
Trainer Drive Emulation can be disconnected from the USB3 system and connected back or to a
different USB3 system and the files on the Drive Emulator will stay intact.
Note: Refer to the UseAssignedAddress setting , which is applicable only to Device Emulation.
