Got Earthmate USB GPS, now what? Options

[lwong]

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

There's one more issue (of course), qpegps doesn't work with the latest versions of gpsd - even if gpsd is spewing data out, qpegps won't recognise it and will remain red - so if you can find out when the changes occurred in gpsd, I'll see if I can find an old version and perform the emul patch on that.

Otherwise, you'll (or I'll) need to use the version of gpsd which the qpegps people have on their site, and try to patch that with the emul patch (sounds like a fair bit of work to do).

Anyway, the moral of the story is ignore qpegps for the time being and just test whether there are any comms by telneting to gpsd, and using emul_test.

The sirfmon and emul_test programs aren't working.

root@tosa:/home/gondola# sirfmon emate
emate: No such file or directory
root@tosa:/home/gondola# emul_test
        em_open: Device or resource busy
        Check node permissions and device attachment.
root@tosa:/home/gondola# emul_test d1
em_open - Successfuly opened device.
em_open: dettached driver hid from device
em_open: failed to claim device
        em_open: Device or resource busy
        Check node permissions and device attachment.

There appears to be something possibly wrong with my libusb install.

root@tosa:/home/gondola# find / -name libusb*
/usr/bin/libusb-config
/usr/lib/ipkg/info/libusb.list
/usr/lib/ipkg/info/libusb.postinst
/usr/lib/ipkg/info/libusb.control
/usr/lib/libusbpp-0.1.so.4
/usr/lib/libusb-0.1.so.4
/usr/lib/libusbpp-0.1.so.4.4.2
/usr/lib/libusb-0.1.so.4.4.2

Although

root@tosa:/home/gondola# ipkg info 'libusb*'
Package: libusb
Version: 0.1.10a-r1

I tried to extract the ipk file to see if the filename matches the one in /usr/lib, but gunzip libusb.tar.gz says Invalid magic. Not sure how else to check it. The command line help for ipkg doesn't say anything about listing the contents of an ipk file, or I'm reading it wrong.
