Not exactly.
VMS automatically looks for and initialises I/O devices at startup
time. (There are exceptions to this but these do not come into
play in this particular situation.)
Autogen is another thing entirely. It is a tool which you run
manually to set system parameters. You don't have to run autogen
to pick up changes in your I/O setup. You just have to have your
device configured the way VMS expects them to be and VMS will find
them when you boot.
It won't if you do a minimum/conversational boot (STARTUP_P1 set to "MIN"),
devices won't be discovered unless the STARTUP CONFIGURE process runs. After
a minimum boot you need to MC SYSGEN AUTO ALL/LOG to pick up devices. Or
just do a full boot.

Does Autogen recognize new hardware?
Yes, definitely. Some older devices have switches (or even
soldered jumpers) to set the CSR address. If some of these
are wrong, it could mess up the automatic address assignment
of later MSCP hardware.
