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.

Okay, do the following:

1. hrw has added libusb to the upgrades feed - install that version
2. Stick my libemul.so.1.0.5 in /usr/lib, create the following symlinks:

libemul.so.1.0.5 -> libemul.so.1.0
libemul.so.1.0 -> libemul.so.1
libemul.so.1 -> libemul.so
(' cd /usr/lib && ln -s libemul.so.1.0.5 libemul.so.1.0', etc.)

3. stick sirfmon and emul_test in /usr/bin (you might need to chmod +x the files as I think they've passed though my WinXP machine)
4. Plug in the GPS
5. Try sirfmon and emul_test (I've no idea what they should do - but please post and tell us)
6. make temporary alteration to /etc/ipkg/arch.conf (post the contents here if you need help) so you can install the next ipk
7. Install my gpsd-emul_2.20-r2_armv5te.ipk
8. Run gpsd with fingers crossed wink.gif

Ok, some results...

armv5te was already in my /etc/ipk/arch.conf file.

Installed the libusb from the 3.5.3 upgrades feed. No problems.

I had to mknod for ttyUSB2 again (lsusb showed the earthmate on device 2) and when I check the ttyUSB files I see

crw-rw---- .. ttyUSB0
crw-rw---- ... ttyUSB1
crw-rw-rw- ... ttyUSB2

ttyUSB2 has a different file mask. Should I just chmod 777 it?

When I went to install the gpsd ipk, I got the same read-only error, and errors about missing libgps, so I remounted my sd card as rw (mount /dev/mmcda1 -o remount,rw) and tried again.

No more read-only errors, but the same libgps error;

"Starting gpsd; error while loading shared libraries: libgps.so.10; cannot open shared object file: No such file or directory

So I went to the oz353 feed and found libgps.so.10 and installed that. It wouldn't install from the SD card, complained it couldn't create the symlinks. think it just tried to create symlinks to the card, which is vfat, not ext2. So I manually copied the libgps.so.10.0.0 file to /usr/lib, created symlinks for libgps.so.10 and libgps.so.

Now when I try to run sirfmon I get:

"# sirfmon emate
sirfmon: error while loading shared libraries: libgps.so.10: ELF file version does not match current one."

Same error when I try to run gpsd. Does that mean I screwed up the installation of the libgps file in some way?

emul_test still gives me "em_open: Device or resource busy
Check node permissions and device attachment."
