I have a Commander Pro that I purchased at launch. I have had it in different systems on both AMD/Intel chipsets over multiple hardware generations, and I have never experienced any problems with it whatsoever. It's always been plugged directly into a motherboard USB header, and always piggy-backed two other Corsair products on its (pass-through) USB headers. I wonder if they changed the internal design at some point, maybe as a cost-saving measure, or due to parts scarcity. Or maybe I am just fortunate with my particular unit.
