System: NetBSD cobalt 2.99.9 NetBSD 2.99.9 (COBALT-$Revision: 1.4 $) #727: Thu Oct  7 17:37:08 PDT 2004  paul@svcs:/sys/arch/i386/compile/COBALT i386
Architecture: i386
Machine: i386
>Description:
	
	The Pharos GPS units use the Prolific 2303x USB-Serial bridge chip.
The Microsoft version (comes with Streets & Trips 2005) changes the device
identifier to 0xaaa0 (AFAIK, bought directly, the Pharos uses the typical
identifier of 0x2303 - an already covered base).  At $100 street price, $129
retail list price and $60 employee discount price (No, I'm not a MS employee),
it is the cheapest available 12-channel GPS that speaks NEMA out of the box
(It actually defaults to 1 sec. reporting enabled) and (of course) JUST
WORKS with "ntpd".
	Only problem - Not supported yet (well, and what to do with the MS
software).
	NOTE:  There are reports that some units of at least one flavor of
the MS USB IntelliMouse uses the same chip and ID (from a Pharos FAQ at
their site), but that only invalidates the comments, the IntelliMouse
should work also.
>How-To-Repeat:
	
	Plug in a Pharos GPS from Streets and Trips 2005.  Look at the
kernel attach ugenX while reporting a Prolific serial device.
>Fix:
	
	The following patches to src/sys/dev/usb/usbdevs and to
src/sys/dev/usb/uplcom.c add support (and of course, you'll need
to change your ntp.conf or whatever the intended application(s)'s
files are).
