USB Mass Storage Device - Driver won't install to save my life...

Oof. I'm going to try to not express my exasperation with this situation in my writing.

Long story short:
Computer: Lenovo y510p, upgraded to an SSD in place of the SSHD last night, reinstalled Windows 7 Ultimate 64 bit, it's running like a DREAM exceeeept...

I cannot for the life of me get the USB Mass Storage Device driver to install (always listed as "failed" in Windows update, and installing driver from Lenovo's driver page doesn't work either). Thus, I cannot get my external hard drive to show up at all. Said external hard drive (USB 3.0 enclosure around a 1.5TB HDD) will show up easily on my work Mac, but the little yellow caution symbol popping up next to USB Mass Storage Device under Device Manager is making my head ache with frustration.

Here's what I've tried:
-Uninstalling ALL Universal Serial Bus Controllers, restarting, reinstalling
-installing driver from Lenovo website product page http://
-Uninstalling all USB controllers and having Windows Update try to install them (Mass Storage is the only one that ever fails, and it ALWAYS FAILS).
-Smashing with a hammer (just kidding...not yet, anyway!)

Any ideas? I've trolled the webs a bit to no avail...it's seriously the dumbest problem I've encountered in a while. Since when do drivers just NOT install properly when they are specifically designed for the product you are installing them to? Is it possible that this driver is somehow conflicting with my SSD (which is an OCZ Vertex 450 Sata III)? I don't know how that would even work, but I guess it's worth asking.

Help?

    Have you installed the "chipset" driver from the Lenovo website first?


    Sorry, I accidentally hit best solution before I even got a chance to try your solution. Does it need to be done prior to the other driver installations? Does install order matter? I know I have the chipset driver installed, but I don't recall what order they were installed in.
  2. Bah, I went and installed the chipset driver again to no avail, though there is now no yellow caution symbol next to the USB Mass Storage device in Device Manager. Still comes up with a Failed when I plug in my hard drive enclosure and it tries to install the driver.

    JUST had a thought and tried plugging it into a non USB 3 port and it worked just fine. so it must be an issue with the USB 3 drivers/controllers?

    On windows 7 you need to install usb 3.0 driver separately. I did and all works fine.
