I have this problem ALL the time on TWO different Windows 7 machine, with two different Unos. It works for a while - but if it's "interrupted" (like I unplug the Uno, then re-plug it in) - get gets into this funny state where, even though the Device Manager sees the Uno going aways and comming back…

Uno shows up in Win device manager - but not in IDE

I suspect a faulty cable or hub.
