damn it, im very sorry i had a typo in my diskperf service so ignore my last
post - i set startup type to 3 instead of 0.....its working now. anyway if
you think this is still the wrong way to go (there is a better sample) please
let me know.
grateful for your help ;)

Doran (or anyone else who can help) - i have been playing with the AddDevice
function - you said above that in AddDevice i can check if the device is on a
USB bus - how to do this ? i assume i will need to do this before
IoCreateDevice, which is the first thing that happens. So i am guessing that
some member of either DRIVER_OBJECT or DEVICE_OBJECT can identify the device
as usb - but i cannot work out how to do this.

thank you.

Now, if you catch one more typo, your chances to get help may improve ;)

Why so many questions about filters at all?
You just need to disable usbstor, this does not involve messing with
filters.

Pavel - yes, disabling the usbstor is the advice that i have been given. by
disabling the usbstor, i assume you are all talking about setting the reg
'start' key to 4. however we have found that this does not always work, and
that we sometimes still able to use usb sticks on the machine. i think it was
when we inserted a stick that was not currently installed, the reg key got
set back 3...so now you will tell me to prevent new sticks from being
installed ! yes we could do that but ideally we want something that can just
enable/disable usb sticks at the click of a button, just like i have already
done for keyboard and mouse, using the WDK samples. so a filter it is, and if
i use Doran's suggestion i can trap usb sticks in the AddDevice function and
give IoCreateDevice some random value so that it doesnt create it as
storage.....it has taken a few days to get soemthing up and running, but i
think the end result will do exactly what we want....

hi unclepauly,

would you give out your soucecode for this, and/or some pointers how it
works and how you install it at class level?

i already have it working for mice (but not at class level, because i
didn't know about that possibility) and need it for keyboards, too. does
your solution work with HID devices? how do you trigger enable/disable?

it would be nice if you could reply to my private email as well - yours
doesn't exist :)

regards,
