I've bought an Arduino méga 2560 compatible on banggood.com. I can't install the driver on windows 7. (I've also an Uno, a mega and a nano that I've installed whithout any problem) I've been on the device in the control panel and tried to install the driver by specify that's on my computer in the arduino/driver directory.
Does someone have an idee ? Thanks a lot for your help
ps. excuse my english....
