Yes, this is in the code. Even ATAPI devices must appear to the generic
layer as SCSI devices.

For USB devices, I use in /etc/fstab (sorry about the spacing):

none            /proc/bus/usb   usbdevfs noauto                 0       0

However, I've not tried any mass storage devices, just a plain jane
optical wheel mouse.

Btw, www.linux-usb.org is a good resource for such things.
