Hi guys,
something really weird started happening recently. The arduino nano causes all my macbook pro's USB to stop working.
It seems to happen only when it is a broken sketch (calling a method on a null pointer, for example). I am upload it am using inotool and opening serial straightaway.
The the mac starts emitting a loud bip sound, like if I was overloading the USB port with extra current, then I unplug the Nano, it stops bipping and all USB ports stop working, as well as the laptop keyboard and touchpad.
The operation system keeps running because I can still access the web server.
The same board and the same upload/serial procedure used to work.
Any ideas?
