Hi,
I connect a GPS through a COM port to my pc running XP. Depending on what
protocol (garmin/nmea) I set the GPS to use, windows sometimes sees the GPS
as a serial mouse: Found new hardware pops up, installs a mouse etc...
after that my mouse pointer gets crazy as my gps is obviously not sending
mouse data. A little bit later the whole system crashes (you must send this
report to microsoft, blah blah, reboot). How can I disable the automatic
detection of devices connected to a specific COM port?
Thanks, Tobias.

Just let windows install the serial mouse thing, then unplug the GPS unit
and disable the serial mouse thing in device manager. Don't delete the thing
or windows will just keep re-installing it. If you disable it you should be
okay.

Thanks, it apparently worked. It took a few tries before XP was up long
enough to disable the damn driver. I now have com4 and 5 used by somehing
although there is nothing hooked up there.
There is a switch /NoSerialMouse to add to boot.ini documented for NT that
suposedly works for XP but it did not do the trick.
Before anything else I need to see how stable the system is...
Thanks, Tobias.
