USB Driver

Hi,

I’m developing a driver for a USB Mass Storage Device. I’m basically trying to replace the microsoft one (USBSTOR.sys). I’ve run into a bit of a problem though and i’m kinda stuck at that point. The problem is that in my FDO I create another child PDO (this is diff. from the one associated with usbhub) that i want to interface with disk.sys. I am creating this PDO when the FDO receives a IRP_MN_QUERY_DEVICE_RELATIONS irp. Help on how to interface this PDO with disk.sys would be greatly appreciated. Thank you.

I wonder what the question was? Anyone like this font? Anyone able to read it who knows the answer(s).

He’s asking how to write his own replacement for USBSTOR.SYS. One of us
who has nothing else to do will probably just do that and e-mail him the
source.

If he’d asked, I’d have suggested writing an
upper filter that would sit above USBSTOR. What I’ll guess he’s really
trying to do is provide some sort of security control to gate access to
the device, and he wants the drive to be invisible if the security gate
is closed.

I think it’s a conspiracy by Linux advocates to cause the most active
members of the Windows driver community to go blind…

Probably. I need new glasses, but that font should be banned.
