Garmin GPSMAP 76C - USB port failure
|
|
| Hans-Georg Michna 2006-06-29, 7:34 am |
| Today I tried to load a map set, but the USB port of my Garmin
GPSMAP 76C failed to connect to the computer. I tried the same
on a different computer with a different cable, but it's
obviously the Garmin device that failed.
Is this a known phenomenon? Is there a workaround to resuscitate
the USB port?
The last thing I did a few days ago was to load a different map
set and some waypoints and routes. I had these same ones loaded
before, so it's unlikely that it is some kind of memory
overflow.
Unfortunately I had just recently given my serial Garmin cable
away with a GPS 12, so I can't try the serial port now. Can the
76C be used with the serial port only, including firmware
updates? If so, then that would be the obvious way out, but I'd
have to make a cable first, which is a lot of work, and the
serial port is very slow, compared to USB.

Try updating the firmware just in case it is a software problem.

Dennis,
thanks, thought that too, but dismissed it at first, mostly
because the device worked fine so far, and suddenly failed for
good, which looked more like a hardware failure to me. I also
removed the batteries from the GPS receiver to make sure it is
cold-started. Still no go.
By the way, when I connect the device, I get an error sound from
the computer, which is different from the USB connect and
disconnect sound.
A problem is that firmware updates are normally done through the
very port that failed.
But I'll make a serial cable later, if no other solution comes
my way, and will also try to do a firmware update through that.

Have you tried the Garmin cable on more than one USB port? I think that
Garmin cable has some electronics built into it as it requires that a
driver be installed before you can use it.
With the driver installed, the cable shows up as the "Garmin USB Device"
in the Device Manager. The GPS receiver has to be on too. for it to
show up. Checking that might indicated a problem with the cable or driver.

That sounds much more like a computer driver problem. Try remving
Mapsource and all map products and the Garmin USB driver, reboot, and
install MapSource from scratch, incl. latest update. Then try
connecting again.

It wasn't the GPS receiver after all. I had recently found that
nRoute didn't work, most likely due to a Garmin installer
defect, and had therefore reinstalled nRoute on both affected
computers, but had forgotten this when the error cropped up. The
software reinstallation probably messed up the USB driver
installation, most likely due to another Garmin software defect.
The result was that on both computers the Garmin USB drivers
were seen by Windows as not installed, even though the Garmin
software saw them as installed, most likely yet another, or
still the same, Garmin software defect.
My message sounds as if I want to criticize Garmin in
particular, but this is not so. We're getting unreliable
low-quality rubbish from nearly all manufacturers these days,
because they cannot master current complexity and because they
have to cater to cheap buyers. I still wish I wouldn't have to
waste inordinate amounts of time on technical failures.
Sorry for the confusion, but I had forgotten about the software
installation, and so the device failure on two different sets of
hardware made it look like a GPS receiver failure to me.
The solution in Windows XP was to connect the GPS receiver and
switch it on, go to Device Manager, right click the device and
select to reinstall the driver. Then simply reinstall the driver
that's already on the computer.

Jack,
thanks for your reply, but see my preceding message for the
resolution. The driver installation was messed up.
The cable, by the way, has no electronics. I don't even use a
Garmin cable, I use a generic USB cable that also works for
external hard disks and cameras, for example.

Firmware updates usually us the RS-232 port .. but he dosen't have
the cable. Sounds like Hans-Georg now has an excuse to buy a new
unit, since this happened with two computers and two cables.

I don't think so. I use a variety of generic USB cables with my
Garmins.

That was a very logical conclusion.

Good to know. Of course, most folks would not have a second
(similarly nRouted) computer and cable to verify that the GPSR was
the problem .. and would likely, therefore, more readily suspect a
computer issue :)

No, he had a problem with the driver on both computers. And it is
resolved by now, as he stated in the German newsgroup.

Phil,
the thought that now I have the excuse to buy a 60Cx actually
crossed my mind, but only very briefly. My 76C hasn't quite
earned its money yet. After all, these things are kind of
expensive, and I do have a budget. (:-)
But fortunately it was a false scare.

Holger,
oh, the crossposting went awry! Don't know why.
But I'm not aware of any German newsgroup. I originally
crossposted to alt.satellite.gps, alt.satellite.gps.garmin, and
sci.geo.satellite-nav.
In any case, yes, it was a driver problem, most likely caused by
a recent nRoute reinstallation. Simply reinstalling the existing
drivers solved the problem on both computers.

I saw that the problem was solved, but I'd point out that I can buy a
pre-built cable from pfranc cheap enough that I wouldn't bother making my
own.

That is good to know and interesting. My cable has a "lump" along it's
length that I assumed housed some electronics. I guess is it just a
ferrite bead too suppress RF interference. Its good too know that any
standard cable will work. I've already decided that I'd like to have a
cable with a right angle connector on the mini-USB end if such a thing
exists. The cable sticking out at a right angle to the handheld is
awkward.
I do like the way the USB port works and the speed of it is pretty good
too.
I'm still figuring things out on my 76Cx and on MapSource too. This is
my first Garmin handheld. I have a couple of older MapSource apps
(MetroGuide NA V5 and Waterways and Lights V3.01) and am still playing
around with those and the GPS and trying to figure things out.

I had something similar the other day, I connected my GPS 60 to the PC and
was told Windows had detected new hardware. The install driver box popped
up, I selected Auto Install, it searched my PC, found the driver and
installed it again. I hadn't uninstalled any programs, but, did run
Registry First Aid prior to it happening so I suspect that was the cause.
Typical, first time I hadn't done a back up after running RFA and before
deleting/correcting.
