devfs is different, and quite experimental.  devfs builds filesystem 
objects for every device automagically, instead of using mknod to do it. 
 The "usbdevfs" is rather like devfs, but it is not the same thing. 
AFAIK it is a kludge to give the same functionality without the 
uncertainty of full devfs support.

Under devfs, you may find them under /dev/usb/tts/0 and /dev/usb/tts/1 
if your kernel is anything like mine.

My linux also automatically mounts /proc/bus/usb as well, in its gpm 
(console mouse) startup script.  This is a "just-in-case" for usb mice.

for the missing 002: how many USB ports do you have?  I have two, so I 
have two entries.  Also, each port creates 2 serial channels for 
usb-serial, one for data interactions, which is visor, and the 0 port 
for some other purpose I am not too clear on.
