Hi,
There seems to be some sort of error here.. each time i plug in the arduino now to my usb port it is recognized as Mouse and it moves the cursor arround (i attached a GPS receiver)..
That is indeed quite strange i think.. any suggestions?

Yes, copyright the design and start marketing it. It should sell like hotcakes

satellite steered mouse... yes, that could do it.. unfortunately there is this 5m error margin - even on the desktio ;0)

Does your computer have any driver that might respond to a serial (RS-232) mouse?  Or a graphics tablet, perhaps?

[Reply #4 on:]

No... not really. interesteringly this only happens (now - after about a hundred tries before) when i have powered the GPS Receiver on the board 0o

[Reply #5 on:]

wow that must have been funny! Or even funnier to see the look on your face in that first moment!

In any case good luck!

ok.. symotoms are as follows:

Everything is fine except when i plug in the board with the GPS powered up at start... would be nice if someone could verify - but well....... dont think so..

Anyway, i still love the idea about that gps mouse ;0)

Need to let the power off of the GPS Receiver

Let me guess - the GPS receiver is connected to the Arduino via the serial port (pin 0 and 1)?

yes, that is right. I already thought that this was the problem, but than again i did doubt it because i anticipated that the arduino designers would have taken such a thing in account when designing it - so i gave up the thought on this being the problem.

You have both the GPS and PC connected to the same serial port, which means that the GPS is interfering with the PC<->Arduino communication. If you need to communicate with both the PC and GPS at the same time you must use SoftSerial for one of them.

I had similar problems before. I think Windows has some legacy RS232 mouse driver that automatically activate when certain serial baud rate is used. Can't remember how I got rid of it now... Have you looked in device manager and see if there's new mouse detected? Maybe try disabling it?

[Reply #13 on:]

Well.. that softserial idea sounds fun )

I will try that one next time )

Disabling that mouse didnt work ;0)

OK, found it.

Go to regedit,

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sermouse

Find entry "Start", set value to HEX 3 (manual) or 4 (disabled). Restart.
