Hi All,
How can I make my Pseudo ScsiMiniport Driver a PnP Driver.
And also when the driver is PnP how should I Inform the PnP Manager of
the
New Virtual Scsi Device so that the FindAdapter routine is called.
TIA
Rahul

First, READ THE DDK DOCS.
Second, DO WHAT THE DDK DOCs SAY.
One key is that you DO NOT define Device and Vendor Ids in
DEVICE_DESCRIPTION. You also need the PnPInterface Key defined in the
registry and you have to have an AdapterControl function and NO
AdapterState. You also cannot pass the context value as anything other than
a NULL. The next trick is how to answer all those blooming PnP IRP_MN
messages your bus driver is going to get. That one I am working on.

Yes but if he really wants to just write a miniport driver he doesn’t
actually have to deal with any pnp irps at all.
W2K scsiport doesn’t really support a ‘pure’ pseudo-miniport, you have
to lie and pretend that you have a resource on the ISA bus. Once you get
over that hurdle it works fine, although of course it is very slow. An
algorithm for optimizing SRB processing without being gated by the timer
callback granularity was discussed here on this group a while back.

Hi,
You’d better skip using SCSI miniport model for this and write own
monolithic PnP SCSI port driver. Or work in your miniport with always
present SCSI devices that support removable media.

You can purchase our virtual SCSI port library which has these problems already solved.
