Here are the USB and /dev/input sections of a patched
linux/Documentation/devices.txt file to give you the latest
device major:minor numbers.
13 char Input drivers
0 = /dev/input/js0 First joystick
1 = /dev/input/js1 Second joystick
...
32 = /dev/input/mouse0 First mouse
33 = /dev/input/mouse1 Second mouse
...
64 = /dev/input/event0 First event stream
65 = /dev/input/event1 Second event stream
...
The current input system is used for USB devices only, however,
it isn't limited just to those, and hopefully will be the way
to access all input devices in the future.
166 char ACM USB modems
0 = /dev/ttyACM0 First ACM modem
1 = /dev/ttyACM1 Second ACM modem
...
180 char USB devices
0 = /dev/usb/lp0 First USB printer
...
15 = /dev/usb/lp15 16th USB printer
32 = /dev/usb/mdc8000 First USB mdc800 camera
...
47 = /dev/usb/mdc80015 16th USB mdc800 camera
48 = /dev/usb/scanner0 First USB scanner
...
63 = /dev/usb/scanner15 16th USB scanner
64 = /dev/usb/rio500 Diamond Rio 500
80 = /dev/usb/dc2xx0 First USB DC2xx camera
...
95 = /dev/usb/dc2xx15 16th USB DC2xx camera
240 = /dev/usb/dabusb0 First dabusb

188 char USB serial converters

The mount point for usbdevfs is easiest used as (IMO):
mount -t usbdevfs usbdevfs /proc/bus/usb
and unmount as: umount usbdevfs
This can be setup in /etc/fstab as:
usbdevfs /proc/bus/usb usbdevfs defaults 0 0
