Topic: Windows has stopped recognizing Arduino (Read 346 times) previous topic - next topic


Hi there,

My PC (windows 7) has stopped recognizing my arduino (uno) boards. When I connect the board, there's no port available in the Arduino IDE. Windows device manager shows an Arduino connected in LPT and COM ports. However, properties of the device show there's no driver installed. Updating the driver just dont work. Also, when i disconnect the Arduino, it keeps showing in the device manager, like some king of unfinished process.

I do not know what to do. I' ve tried to use other drivers. I also tried to uninstall the device from my PC, but nothing works.

It would be really nice if I can get some help.


Which other drivers have you tried ?

Are they using the CH340 drivers maybe ? (not included with the IDE)

You really need to supply some specific details or screen shots or error logs etc etc.
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

This has happened on multiple boards? Have you hooked up other hardware to all of these boards?
