OK, I'm really stumped. My Nexus charges just fine with a third-party mini (universal, right?) USB in my car, charges just fine with the mini-USB charger I have in the bedroom (another third-party) but doesn't charge with either of the mini-USBs we have in the kitchen (we have a charging valet there for all our phones). Everyone else's phones in the house (A Samsung Resound, Moto Droid X, even Kindle) charge just fine on these kitchen cables. Anyone else run across this problem?
