    Greetings to all windows phone users and devs.
    I experience the following problem with my Ativ S.
    When i try to connect it to my computer, windows(i have 8.1) can't recognise it. At the device manager ativ s shows up as "Unknown USB Device (Device Failed Enumeration)" when i connect it at a USB3 port and when i try to connect it at a USB2 port it shows up as "Unknown USB Device (Port Reset Failed)". I found that windows are experiencing this problem with the device: "Windows has stopped this device because it has reported problems. (Code 43) A USB port reset request failed." so i tried to hard reset the phone. Nothing happened. So i headed to the diagnosis app at my phone and typed *#7284# to enter Micro Usb Test but when i typed it the following problem showed up:
    I also tried to connect the phone without the micro sd in but the same as above happened.
    My phone info:
    What do you think is it broken?
    Forgot to say that my phone charges normally through usb port

    Yes i tried with the original cable ofc and with another one cheaper that i have.
    Installed it but yet the same problem...
    By the way i tried to connect the device from linux that i have but with no luck.
    Tomorrow i will may try with another computer but if nothing happends again, should i try to downgrade my ativ for a start?

    thats a HW or SW failure
    you can "repair" only the SW problems so try to revert back to basics
    if this process didnt help then the problem is with the HW
