Just purchased and set up a NEW Xbox 360 console. All appears to be functioning properly [xbox live account, updates, downloads, etc...] except, only 1 of the 4 wireless controllers I purchased are able to connect. I have followed all the instructions to connect wireless controllers [replaced batteries, etc...] but, I am unable to establish a connection for 3 of the 4 controllers. Is there something I'm overlooking? Any help would be greatly appreciated. I find it hard to believe that I have acquired three controllers that are malfunctioning. Thanks for your time.
