It's working now and I've been able to read back data from
my Garmin GPS device on FreeBSD for the first time!   

I've noticed a couple of issues while getting it working.  The first
is that I get a message when I plug the GPS in, but not when I unplug
it - I'd expect to see something like "ugen3.1: at usbus3 disconnected".
It gets attached on the ohci hub; usbconfig reports it as:

ugen3.1: <OHCI root HUB ATI> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps)
pwr=ON ugen3.2: <product 0x0003 Garmin International> at usbus3, cfg=0
md=HOST spd=FULL (12Mbps) pwr=ON

I've built the stack as modules, and just 'kldload
usb2_controller_ohci'.

The other issue I bumped into was when I was trying to get gpsbabel
working.  I tracked it down to the code that selected an endpoint
address: my Garmin has addresses 0x81, 0x2 and 0x83 but the USB stack
wasn't happy with gpsbabel sending the result of those addresses ANDed
with USB_ENDPOINT_ADDRESS_MASK.  When I passed the addresses
themselves, gpsbabel sprang into life and read data back from the
device.
