USB mass storage device driver

NTDEV
1

Hello guys.

I’m fairly new at USB driver development.
I do have some experience with Filter drivers though, so some things seem familiar.

I’m trying to demonstrate the possibility of identifying by a driver, the event of plugging in a USB storage device.

I’d like to be able to distinguish between storage devices and other types of usb devices (hubs,HID etc.)
How does the OS know which type of usb device was plugged in?

Any clue how to start?
I tried looking at the DDK’s filter in the Toaster example, but it won’t install itself properly.

Thanks a bunch,
Ariel.

Well I’ve never done it at the USB level, but it is fairly easy to have a
storage filter, and in AddDevice query if the bus is USB. In my case, I
did not attach the filter except for USB devices.

Volume filter drivers are a good level for doing just this.
