    As per specification details this model has a Intel's 6th generation of processors, also known as Skylake or Kaby Lake  CPU.  Intel Skylake Removed Support for USB based Windows 7 Installation. Microsoft ihas removed support for the EHCI host controller (USB 2.0 spec) and keeping only the xHCI host controller spec (also known as the universal USB 3.0 specification).  

     
    You can check the name of the CPU by opening “System” by right clicking the “Start” button, and then choose “System”. You can find CPU type in item “Processor”. (or) Enter BIOS Setup Utility by pressing key “F1” frequently when system boots. Then switch to “Main -> System Summary”. The CPU type will be listed. 

    Please try insrtalling the drivers listed this weblink
