In terms of devices that look like serial ports, we don't have a public
API/SPI for adding new serial drivers to our framework, however that
is something that we are looking at providing in the future for just such
cases as yours. We are also considering providing a CDC (USB
Communications Device Class) driver to handle the increasing number
of devices that are implementing the CDC spec.
Ooh ooh - would that support http://www.ibuttonlink.com/linkusb.aspx?
It's based on a FTDI FT232R USB UART, which can emulate a DS2480B, both
of which appear to be quite common these days. Even OpenSolaris has a
driver for the FTDI USB UART:

It looks like it supports CDC mode, although that's just one possible
device profile it seems (Page 10, Table 4.2 of
http://www.ftdichip.com/Documents/AppNotes/AN_105_FTDI_Device_Programming_Using_Vinculum_VNC1L(FT_000078).pdf).
So I don't know what that means. If you have to place it in CDC mode in
the first place, how do you do that if all you have is a CDC driver???
Or maybe that's easier with Sun Ray drivers. I suppose one could write a
simple driver that claimed the device, primed it for CDC mode, and then
handed it over to a CDC driver?
