I took the plunge and got the Delorme Earthmate USB GPS.

The 6000 recognize it right away as "Delorme USB Earthmate". dmesg says something about

USB HID v1.00 Pointer [Delorme Publishing Delorme Earthmate] on usb 1.27.0

Now what do I do? I installed qpegps but the defualt path is

-p /dev/ttyS0 -s -4800

Is that for connection through serial cale? What should I change it to?

One good thing about the setup is that the Z can power the GPS all by itself. The bad is that if qpegps is run in 640x480 mode, it looks skewed.

Please help me set this up.

Thanks

This is part of the solution outlined there - you also need to have the USB devfs enabled. I'm not sure whether this is enabled by default on the Z.

Anyone? In any case the patch against gpsd is on the web page, just patch it and build and see whether it works.

Otherwise there's always the kernel module which probably wouldn't be too hard to build. Which kernel are you running (the standard Sharp one I suppose, not OpenZaurus by chance)?

Actually, it turns out that it's more complex than that.

The posted 2.4.x patch does not work with the Sharp kernel sources. I tried that. Someone with more programming experience may be able to update the kernel, but it's not a cut-and-dry kernel patch.

The other option, recompiling gpsd, requires some libs that I didn't have, and I got lost trying to figure out what libs I needed to get it working, and how to compile them. I think it may need a kernel change either way. I couldn't get it working, even though I was able to get a compile environment set up and I was able to compile and run a QTopia sample app.

I would really appreciate someone looking into this. Having recently lost my job, I don't see myself wasting the money for a new non-USB GPS, since the Z is not something I use for work.

Once I have a working GPS, I'd love to work on some map conversion projects, etc, but my Linux C programming skills are meager to say the least. I'm more comfortable with Perl and PHP.

Bump.

I'm still interested in getting my GPS working before my upcoming road trip, wedding, and honeymoon. I'm going to be driving from NC to IN, flying to Vegas for honeymoon, flying back to IN, then driving back to NC. I'd like to have the GPS available for the trip, but I need someone with more expertise than I to patch the kernel and compile the patched GPSd.

I'll use OZ 3.5.3 if you want to compile for that platform, or stock Sharp ROM, whatever.. as long as I can use a browser and a GPS app.
