Hi,
I am new to device drivers programming.
I am interested in finding out is there a way or possible to filter all
devices that is connected to the system.
Meaning all accessing needs to go through this driver before it goes to
the specific device driver.
I wanted to try to filter all removable devices regardless how they are
connected to the system. Can be PCMCIA, USB, Firwire, Parallel, Serial or
Infa-Red.
Is it possible to do such things?
And regardless of the device, be it floppy, cdrom, dvd, hard disk, cdrw,
or flash memory.
I have tried to filter on the FILE_DEVICE_DISK and have put my filter
driver as a UpperFilter in the Disk Drives, it can only filter removable
devices but not removable floppy drive (USB type). And if I put the filter
at Floppy Drives entry I will be able to filter floppy.However I find it
troublesome as each device I have to put my filter in that entry.
Is that a global place I can put my filter driver?
Thank You!
cheers,
vincent
