Installing drivers

Something that's bugging me, let's say I develop a simple driver that all it does is allows reading and writing of data blocks to/from a USB device, can this be installed without administrator access on the PC, or do I have to be admin to install any kind of driver?

Thanks.

Yes, you do. In all type of OS that implement security level, users are not allowed to load
and release device driver.

Ok thanks, that makes sense.
