I think you can't find /dev/ca[01] because it actually says 
/dev/cau[01], and that would be wrong anyway, for two reasons, one 
relevant here, and one not.

The suggestion to use /dev/cua[01] is for if you have a serial mouse, 
not a bus mouse.  Since you have a bus mouse, it is wrong for that 
reason.  It is also wrong because the /dev/cua[01] are considered a 
design mistake by the kernel developers, and they have dropped official 
support for them a -long- time ago.  It's just that not all the 
documentation that refers to them has been properly updated.

The Busmouse Howto says that Linux only supports four busmouse 
interfaces -- Inport (aka Microsoft), Logitech, PS/2, and ATI-XL.  If 
your mouse connects to a special card in your machine, it could be 
Inport, Logitech, ATI-XL, or none of the above.  If it plugs into a 
small round connector that looks like your keyboard connector, it's a 
PS/2 mouse.

If it's PS/2, you can use /dev/psaux.  You may have to compile in 
kernel support, however.
