Kawasaki KL5KUSB105 USB to Serial driver

[Steve Lin]

KLSI makes a USB to 4-port RS232 device, part number KL5KUSB105.  Anyone
know if this device is supported by any of the USB to serial drivers in
5.0-current?

If not, is anyone aware of a project to support this device?  Any idea how
hard it would be to port the linux driver for this device to FreeBSD? 
(I've written device drivers before in a past work life but never for
BSD).

Thanks,
Steve Lin
