My PC (with 32-bis Vista) cannot detect Arduino UNO board any longer and the codes cannot uploaded either (I wanted to refine my code).
I manually forced to add the port (COM & LPT) through device Manager dialog box but still, the problem remains: though the port is correctly installed and updated it's given a message::
"This device cannot start. (Code 10)" on the Arduino UNO (COM X) properties dialog box.
And indeed when the Arduino application is launched the COM X port is not available.
On the Arduino UNO board the single orange light (L 13) stays ON in addition to the green power light.
Your support is very appreciated!
