    Thumbs up Earthmate LT-40 Com port freeze problem - Resolved

    Not sure if this has already been documented somewhere, if it is, please ignore.

    Thought I might share this. I have an earthmate LT-40 gps mouse using delorme's serial emulator used with iGuidance.

    For the last 4 months (since i assembled my CarPC) whenever I started the computer, I would get Errors like "Path - 2" and "Error 4 - Contact your vendor". The ports would freeze after 15-20 minutes of use and make the maps freeze as well which was really annoying. Restarting or logging off and on again would solve the problem for next 20 minutes or so.

    Well I saw this solution to run emulator in compatibility mode (XP SP2) in Vista. I have XP SP3, wasnt sure that was the problem so, I decided to check the options in XP. If you right click the executables in the Delorme Serial Emulator directry and set compatibility to Windows 2000, no more errors. Hibernate Resume / Log off-On works perfect and I have not seen port freeze after this change since yesterday.

    Update: It didn't work. As I drove through a bump, the error started coming back. It could be loose connection, will have to look into that. Sorry for jumping the gun.

    Update 2010-01-11
    I think I finally have resolved the issue.. I used a BT GPS without disconnenting LT-40 but un-installing the drivers and the BT GPS froze after an hours use. This made me check the device manager (wish I had checked this a long time ago). Anyways the LT-40 was identified as a HID mouse. Disabling the device and I have not had the Path 1/2 error so far (a days use).

    I have the same problem with XP SP3. I tried Vista Enterprise edition and got the same errors.

    I am back to XP SP3 and the problem persists. I think I am going to have to ditch using this receiver for Centrafuse' purposes and go with something else.

    The LT-40 works perfectly fine in native mode with Street Atlas - its a shame their serial port emulator seems to be a dog.

    It did seemed to work for a few days after i reconnected to a different port and the extension connector. Then its back to same errors. I am searching for a new gps mouse, am really tired of unreliability (though very reliable with SA as you mentioned but then SA is really not for the CarPC environment).
