In fact, it is available in userland code as part of code I 
contributed to the coldsync package (also in the FreeBSD ports
tree).

The protocol used with the Handspring Visor and Visor Deluxe
was reversed engineered with a USB protocol analyzer and is 
essentially the same as the serial line protocol but using
a USB pipe to carry the bits.

Other USB-attached Palm-like devices do something different
which doesn't work with the code that I wrote.  Having this
in the kernel is unlikely to make it *easier* to support, but
what the heck.  The kernel driver will presumably also work with
the other legacy PalmOS sync packages that expect at TTY device.
