I'm already aware of this and I don't understand how this answers the question in the comment you replied to. Maybe you meant to reply to a different comment?
Yes, a user-mode driver is something you would write instead of a kernel mode driver, if you can. Kernel-mode code is the most powerful, but also poses the greatest security and stability threat to the computer, so Microsoft locks it down the hardest. If you don't need the extra power, you can write a use-mode driver that uses Microsoft-provided kernel components (Like Winusb.sys) and you don't have to go through the same security procedures.
