Re: Starting a driver within a driver...

A proposed feature of longhorn will be that the OS supports multiple
asynchronous starts. I am pretty sure all other OS's synchronously start
the devices.

Sigh. You're right, as usual...

Anyway, am I correct in guessing that it would work on XP and 2k3? They

no, you can't pend the start irp. on a lot of OS variants, the pnp enum
