USB question/problem

I bought myself a Garmin Nuvi GPS unit for after Xmas. It has a USB cable for hookup to Macs and PCs. Supposed to be compatible with G3s forward running OSX 10.4.11 or later. It doesn't show up on my desktop, which then won't allow it to communicate with Garmin's software, or website for upgrades. It shows up fine on my Acer PC. All my other USB devices work/show up fine. Anyone have any experience with Garmin units and Macs?
I've plugged it directly into the computer with nothing else but the keyboard & mouse connected. Done a restart. Shut down, unplugged for 1/2 hr or so and restarted. The unit knows it's connected, as it shows the connection icon on the screen. The computer doesn't recognize it. I'm out of ideas, any suggestions?
System is a G4 running 10.4.11, 1.5 GB memory.

Some USB devices require more power than the Macintosh USB port can provide. Try using the Garmin with a powered USB hub unless you can be certain that it requires less power than your USB port provides.

It doesn't show up on my desktop... Apologies if this is too obvious, but how are your Finder Preferences -> General -> Show these items on the Desktop configured? Some types of external devices seem to be treated by the OS as being in a different category than what common sense would dictate. Failing that, does System Profiler see the Garmin?

All 3 items are checked to show on the desktop. And no, System Profiler doesn't see it either.

Also sorry if this is obvious, but is there any attendant software that may be incompatible in some way?

It doesn't on the Mac. It does on the PC. The software doesn't need to run to see the device on the desktop, but the device needs to be on the desktop for the software to find it. I'm wondering if there was maybe a change in the USB driver in a software update that I haven't installed that would cause the Mac to recognize it.

It is probably time to get in touch with Garmin tech support about this issue. Please let us know how the problem is resolved.

They don't have a solution, but think it's a problem with my Mac, since the PC recognizes it. My next step is to try it on another Mac, but that will have to wait until my next trip into town. I also have a friend with another garmin model that I may try to hook up to my system to see if it is recognized.

I had a similar problem with Garmin a few years ago. That is exactly why I have a TomTom today.
If we knew what it was we were doing, it wouldn't be called research, would it?

As part of your experimenting you might want to check out the Yahoo Group macmap, which provides good info about GPS use with Macs, including ‘ the status of many USB devices and their interaction with GPS units including Garmin’.

Just because it's USB doesn't mean that the manufacturer had his head any place than up his fundament. It could be because the product is defective, the USB cord is damaged, your USB port is damaged, or the manufacturer put in something proprietary that causes the USB port to not be device independent.
Check your USB cord first.
