Re: Selectively disabling USB devices

Pranav,

I am not aware of a free possibility (if you ever do, please let me
know) but there are many commercial software who can do this by using
the USB device ID to permit/deny the use.

It only works if the user is not an administrator although I assisted
a presentation by Verdasys (Digital Guardian) which claimed they could
bypass this issue by hooking in the kernel at boot time. I'm not a
Windows engineer so I can't confirm is this is real or bogus but the
presentation seemed satisfactory for me. Unfortunately, we haven't
opted for that product.

Instead we used a tool named Device Lock which can do the same thing.
We don't have a problem with users being administrator so this works
fine.

Please note that (as far as I know), Firewire doesn't have different
IDs per device so you can only do "disabled", "read" or "read write". 
USB provides much better managability.

Is it possible to selectively disable USB devices? For instance, only mice and
printers should work when connected to a USB port but flash drives, other mp3
players etc should not work when connected to the same USB ports.
