  • Fixed now - My problem was: Zune displayed “No device connected” but Windows 7 detected and could eject the htc Mozart Windows phone. I had three replacement htc Mozart Phones, used same htc USB cable and USB port on my laptop.

    First, try the proper htc USB cable in each USB port on the computer - best to use the rear USB ports on a desktop. My laptop now works on all 4 USB ports, but some software (USB printers) only works on the same USB port it was installed on originally.

    Re-installing Zune did not fix it. None of the 4 USB ports worked. Deleting all USB devices and USB hubs and restarting and letting them re-install, then re-installing Zune did not fix it. The same phone and cable worked OK on another laptop with Zune.

    My fix: I fixed my Windows 7 Enterprise laptop by uninstalling Zune, seizing ownership of the reg key below and all USB devices, then deleting the key below, disconnected phone, then re-installed Zune then plug in the phone again:


    Microsoft FixIt did not fix it for me. Other things you could try:
