What does the current source do on this unit?

Just on a hunch, I'm going to guess that this model has a USB implementation
that's broken in the same way as the Venture HC which is about the same
price point.   Search for "Zero is" in jeeps/gpslibusb.c and see if
commenting out that "default:" line makes your GPS play nice.  If so, we
should figure out the ID (I'd decode it from the hex dumps, but it's
late...) of your GPS and add it to the list.

Thanks Robert!

Your hunch was correct.  Your suggested change makes the 
Garmin 72H work in gpsbabel-1.3.7-beta20100215.
I changed the default line to a "break;" like all the other 
special cases.  I am now a happy camper.  Unfortunately
I cannot yet read the hex dumps to find the units ID and make
this a permanent change usable by everyone else, but if 
someone else decodes the ID I would be happy to recompile
and test it.

All the best.

That's why I get all the hot groupies...

You should now be able to  get GPSBabel to tell you the ID now.

./gpsbabel -D1 -i garmin -f usb:
GPSBabel Version: 1.3.7-beta20100215
Unit:    GPSMap60CSX Software Version 3.60
ID:    292
Version:    3.60


Report that ID and I'll apply the tweak.

If you can confirm this unit allows 14 character waypoints, allows lower
case and spaces we'll add it to the table around line 186, too.

The GPS Id is:

GPSBabel Version: 1.3.7-beta20100215 
Unit:	GPS 72H Software Version 2.30
ID:	1095
Version:	2.30

Unit allows only ten chars in waypoint names.
It does allow spaces.  It converts lower
to upper on input from gpsbabel and truncates 
to 10 chars.

aside::
I bought unit (first GPS) to find some corner
markers in heavily wooded and steep terrain
in northern california.  It worked for this,
Wanted cheap capable unit.  Unit has WAAS, and 
seems competitive with other handhelds with 
decent built in antennas.  Tracks 12 satelites.
Usb support was important.  I like paper
charts and maps so built in map support not
important.  Waterproofing is, i can use it 
in Kayak.

I am overall pleased.  Biggest failing for me
is lack of external antenna support. The
slightly cheaper eTrexH has manny of the same 
features, but slightly smaller display, no usb 
support, only serial port and doesn't float.
(I haven't verified this.  If someone has
one of these units could they test this out?)
end aside::

gpsbabel works great with this unit over usb.  
Have tested most options.  -T to continually 
update computer doesn't work as expected, but 
isn't really needed by me.

Thanks for support.
Regards
Otto

So it's closer to a 60CS (no x) in waypoint handling, but a Venture HC in
brokenness of USB stack.  Nice.   I'm baffled at how these guys keep
cranking out products with a mixture of old and new traits.

Here's what I"m going to apply:

Can you confirm that brings happiness?

I'm not a fan of the yellow eTrex at all.  Serial GPSes can not disappear
from the plant soon enough for me.

(And by the time you bought the serial able and a usb/serial adapter, it
probably wouldn't have been cheaper anyway.)


Thanx for talking this through.
