(Redirected) Using USB 3 on E5400

I have an E5400 and wish to use USB 3 via either a PR03X docking station with USB3 ports or with a caddy and ExpressCard USB 3 for the PCMCIA slot.

I have upgraded the machine to Windows 10.  I do understand that Dell doesn't support this upgrade, but it works fine so far.  The only problem is that when I attach the PR03X and connect a USB 3 device to the superspeed ports in the back, the device only runs at USB2 speed.

Checking the device manager, no USB 3 devices are shown.  Attaching the docking station generates "Generic USB" devices, but Windows 10 doesn't appear to recognize the USB 3 ports as such, even though the Dell diagnostics show the attached device as USB 3 capable.

I tried upgrading the Intel chipset to enhanced, but the installation says this machine is not capable.

I didn't try the USB3 via docking under Windows 7, so I don't know if it worked then or not.

Is there some combination of chipset and driver updates that will allow me to use USB 3 on an E5400 laptop?

Any suggestions would be appreciated.

There are some BIOS updates available for this laptop, but since I have already installed Windows 10, I am concerned that updating the BIOS may cause problems with Windows.  If this is not the case and I can apply those updates without harm, could doing that help solve the problem?
