Yes, user-space drivers would require access to /dev, yes, but kernel 
drivers not, like mouse, keyboard, storage, network.

A so-called composite USB device may appear like a USB storage device 
(kernel driver) and a security token (firefox). Firefox can only grab 
the device if you set the proper permissions for /dev of course, but the 
reset device IOCTL then also becomes possible, which is why we currently 
block it for non-root.
