Hello everyone,
I have a Dell Inspiron N5110 laptop and for a few years I haven't been able to get my USB 3.0 ports to work. I believe I might have messed up the driver installations when I first got the laptop.
I got a new hard drive lately and decided to test my USB 3.0 ports before installing Windows 7 because I will really need them for work soon, so I tried them on Windows 8.1. They worked automatically without having to install any driver (I think 8.1 has its own 3.0 pilots?)
So I formatted my hard drive and installed my Windows 7 Home Premium 64 bits. I downloaded all the pilots from this page (www.dell.com/.../drivers) in another computer and placed them on a flash drive.
After installing Windows 7 and booting for the first time, I tried my best to follow the order explained here: www.dell.com/.../how-to-reinstall-drivers-in-the-correct-order
I started with Dell System Software Utility (DSS_UTIL_WIN_R282538)
Then Intel Management Engine Interface Driver (R292194)
Then Intel HM67 Express Chipset Family Driver (R292253)
Then Wistron USB 3.0 Host Controller Driver (R309746)
And after each driver installation, I would reboot my laptop. But when installing the Wistron driver, the R309746 file extracted itself and then nothing happened. So I went to the C:\dell\drivers\R309746 folder and tried to launch "setup.exe" again from there, with admin rights, I received the window of "This program might now have installed correctly" and I had two options, "Reinstall using recommended settings" or "this program installed correctly".
When I pick "this program installed correctly", nothing happens and my USB 3.0 don't work. When I pick the other option, nothing happens too.
I tried this 3 times. Each time I format the hard drive again and I reinstall Windows and I reinstall the drivers, trying different orders sometimes, but to no avail. My usb 3.0 ports are still not working.
Can anyone please help me? Did I do something wrong? Did I mess up the order of the installation of the drivers? What should I do at this point? I'm really getting desperate since all these trials have already cost me almost 2 days.
