Hello Arduino community.
I really like the arduino platform, its a great way to make prototypes. I find myself, however, sometimes frustrated with my one single greatest problem. Being unable to upload.
Today my laptop with linux on it suddenly couldn't see the port to which the arduino was connected. I tried all usb ports, also as root/super user, but it did not work. I have had the same problems on Windows. Its the kind of problem, that all of a sudden fixes itself, but usually first at the point where you are sitting in a corner crying cutting your wrists in a state of frustration and anger.
my question is, what is it that happens when the software suddenly stops recognising that a device is plugged in? and is there a way to fix it?
