I have installed Windows 7 in Acer Aspire E5-551G, but it doesn't seem to be a supported OS by ACER, because in the ACER Drivers Download page, the drivers are only available for Windows 8.1 I have manually found and successfully installed the different drivers for Windows 7, but I am not able to find the appropriate driver for 'Universal Serial Bus driver (USB)', and I suppose that this is.

Note: The Intel® USB 3.0 eXtensible Host Controller Driver is not supported on Windows XP* and Windows Vista*. This is a new version release: 5.0.4.43v2. Not sure if this is the right driver or software for your Intel® chipset? Run Intel® Driver & Support Assistant (Intel® DSA) to automatically detect driver or software updates. I installed the chipset and pci controller drivers, so I'm not sure what's causing this. USB xHCI Compliant Host Controller' has error code 10.
