Hi,
Not sure if the keyspan is suported or not.  But if it is
recognized, it should show up via 
usbdevs 

e.g.
% usbdevs 
addr 1: OHCI root hub, ATI
addr 1: OHCI root hub, ATI
 addr 2: USB FAST SERIAL ADAPTER, FTDI
addr 1: EHCI root hub, ATI


Take a look at the man pages for ucom and the various drivers that
support it.

Re: Connecting to a USB serial port

 I have a Keyspan USB serial port on my FreeBSD 6.1 box and trying
 to connect from a Linux box to the machine. I'm using minicom and
 not sure of the settings that should be used. I see the following
 in dmesg...

 sio0: 16550A-compatible COM port port 0x3f8-0x3ff irq 4
 flags 0x10 on acpi0
 sio0: type 16550A

 Is this the USB serial port? There is no other serial port avaialble
 on the server, but could be something in the board, not sure.

I doubt it.  That looks like a normal board-resident serial port,
esp. with the on acpi0 notation (which suggests that it is part
of an ACPI-controlled device, and ACPI is ordinarily aware of only
motherboard devices).  It's likely part of the super-io chip,
and it may possibly be connected to a 10-pin Berg header on the
motherboard (or it may not be connected to the outside world at
all).  The motherboard manual, if available, might provide a clue.
