RE: XPS one 2710 USB 3.0
If we go by that list than more than 50% of the products that are sold will not be compatible windows 8.1. 🙂 Anyways now the interesting thing... The PC recognizes my phone when connected to the back USB port but it does not work with the side ports.
The side ports are actually functional as it can detect USB 3.0 drives and other USB 2.0 hardware like iPhones etc...
Hence I am not sure whats happening,
