jumping mouse

Fellas

I have been trying for the better part of a day now reasearching and trying cures for the jumping mouse on my cf-28 with gps. So far i know that it is not a hardware problem (ie somthing broken), and that it is most likely because the gps data is confusing the mouse. If i disable the gps in the bios the mouse behaves well. I have tryied the suggestions as far asdisabling the gps starting the pc and changing the settings of Com 4 this has not helped. In my configuration I am not allowed to disable the PS2 mouse whis is one of the steps that was suggested to correct the problem. What i was wondering is for thise of you using the em408 with the factory daughterboard, is there any way of changing the settings to anything other than com4? My gps software (iguidance) will let me select com ports and baud rates; so what I was thinking was if i could do somthing to the em408 and or daughterboard to make the gps a different com port. If this is not feaseble I am curious how many of us out there have not been able to correct the problem.


thanks

 

Even if you correct the problem on jumping mouse you still have a problem on getting a good signal coz it is very poor on antena design. Best is to change the module and antena.

 

You should see 2 devices under Mice and Pointing devices in Device manager:
1. Microsoft Serial Ballpoint
2. touchpad/touchscreen

Is this what you see?

The fix is to disable only the Microsoft Serial Ballpoint.

That will not disable your touchpad, or touchscreen.

 

Do the easy thing, and go into the device manager, and change COM 4 to COM 7. Should fix the jumping mouse issue.

There is a setting in there to allow you to do that if you open up the properties on COM 4. However I'm not near a windows machine at the moment, so I can't direct you exactly.

 

I knew I should have brought my tbook home today...I have not tried that.
Its in device manager...Mice and pointing...COM4...port settings tab...Advanced

i only see the touchscreen under the mouse properties in device mgr. i do not see a serial mouse listed. i will try and change the name from com 4 to com 7 and see what that does. i will let you know soon.

your comment has me puzzled are you refering to the stock gps engine? i am using an em408 along with a jim grey antenna.

take care

Whoa....I havent heard of the jumping cursor with the 408 before...

My comments were assuming the factory GPS...

I thought both mouse entries came from the touchpad/touchscreen driver though.

yep its the 408gps i tryied to change the com port to 7 like you suggested and it still jumps all over. I am going to try disabling the gps in the bios one more time now that the port is renumberd and see if it still jumps.

 

I show ToughBook as being online, you could PM him to see if he has any insight on this since he was one of the first to incorporate this mod.

 

i have played around with various settings and so far what has worked was uninstalling the touchscrene drivers and putting back the default ps2 mouse drivers. I have tryied disabling the gps in the bios, changing the com port names settings and all that seems to work so far is removing the touchscrene drivers. I will try playng around some more but i wanted t post what i have ran into so far.

 

Oh! sorry. I thought its the stock gps engine. Disconnect the module and reboot and then power it off. Since you set it up in to many ways, load the default setting of the bios first.Now connect the gps and reboot go to bios setup to enable or auto the gps.

 

ohlip/others
should i leave the com port irq settings set to manual config or put them bac to auto?

 

Just to auto mode and will gonna be fine.BTW, before you connect the gps engine make sure all the drivers of toughbook installed and operational.

 

Ok, Modly's recommendation works for me (Factory GPS)
Once you disable the Serial Ballpoint, change COM4 resources to a set that works...(GPS test here)...then, in device manager, Ports, COM4, Port Settings tab, change it to COM7.
Now after reboots my GPS (factory) works without having to keep changing the resources for the COM port.

 

We are talking about the new engine here, not the stock gps.

 

It doesn't make any difference, this problem will occur with any GPS receiver connected to an actual serial port. It may not occur with USB receivers.

 

This is the reason it happens.

GPS data is all transfered via serial (However with USB, it's converted, so it won't usually cause issues).

The mouse also inputs data through serial.

When GPS is sending serial events, and it is routed through the same port that the mouse is (COM 4), it'll send data that the computer thinks is the mouse. It'll pick up whatever resembles a mouse event and relocate the mouse.

That's why changing COM 4 to COM 7 usually works, because it re-routes the data properly.

Which version of the touchscreen driver do you have installed?

 

I remember when I ran Windows in the Win9x days, and there can be an IRQ conflict between a serial mouse and COM ports. It's been too long now to remember, but it seems like I changed IRQ on one or the other to something unused. Using COM7 sounds like it would be easier.

 

I hate to bring up an old dead thread but, I am trying to get the factory GPS up and running. I have the jumpy mouse issue and have tried all of the com ports to no avail. This of course is with the Microsoft ballpoint mouse enabled. I tried to get Winfast navigator up and running but it doesn't see the com port of the GPS when the ballpoint is enable. If I disable it the software sees the com port and starts streaming data however it is not picking up anything. Is the GPS disabled if i have disabled the ballpoint mouse disabled in device manager? Why is this so hard to get the mouse and the GPS to work? I currently have all serial ports and IR disabled in BIOS to help sort this out and keep the amount of Com ports down to one The GPS. Is the Ballpoint mouse something to do with the touchscreen or is it the OS recognizing the GPS module as a mouse incorrectly?

 

The Ballpoint mouse isent used for anything, it should remain disabled.

As for streaming data, but not picking anything up, thats why everyone is retro-fitting a new GPS engine. If you go outside, you'll eventually get 1 or more locks, and start streaming meaningful position data.

 

Well I have the the GPS working and I get good signal out side with 6-7 sattelites. The only other question would be is there a way to remove the Ballpoint mouse from the device manager so it doesn't get redetected or enabled by someone that might see it disabled in the device manager and re-enable it?

 

A jumping mouse could be caused by poltergeists, or cruft on your computer.

 

Poltergeists were exorcised and computer is at cruft level 0.
