Ok, wth is going on here?? now i got it connected to my pc, and this is the result (image 1).
the error i get from the app is the second image.
I really don't understand it anymore. in the hardware manager it says it is on COM3, but the IDE and the app are saying COM3 does not exist, this is a strange thing going on imo.
In fact i don't really know if this still has something to do with my arduino, since it shows up in the hardware manager as it should...
edit: a little more info on the app
It's written in VB2010, and uses standard serial communication. i added a serial port, of which the communication works fine.
I'm running the app in debug mode, so i haven't compiled it for real yet. (maybe this has something to do with it, i really don't know anymore).
