USB Root Hubs missing after windows 7 clean install
After a 'convoluted' clean install of Windows 7 Professional 64bit on a pre-installed Windows 8.1 system [secure boot disabled and re-formatted hard drive] I seem to be missing all the USB Root Hubs although the USB3 hubs are there and I have reinstalled the Intel chipset drivers. All the USB ports are working properly both USB2 and USB3 but when I try to install a HP Photosmart printer as a usb printer [it does not give me another choice] the installation stops at detecting system settings: no USB drivers installed.The question is: do I have to do another clean install of Windows 7 or is there some way of downloading the USB2 Root Hub drivers from Microsoft or Lenovo? Has anybody ever had this problem? sfc /scannow hasn't found anything missing.
