On one occasion on three machines, the UNOs would not connect. Drivers were removed and reinstalled (from a terminal level). Still didn't connect. In both cases, I swapped the UNOs for 2x2s and they worked fine.

On three additional occasions using different machines, after reboot the UNOs did not come online and had to have drivers reinstalled.

In every case, switching to a 2x2 or something better has worked. I will admit though that I haven't used an UNO since Fall 2009. Maybe the drivers are fixed.
