Windows 7 - USB 3.0 Hard Drive won't auto-detect

Maybe a couple weeks ago I bought a usb 3.0 hard drive. At the time I didn't have any USB 3.0 ports, so I was limited to using in my 2.0 ports. Two days ago I got my hands on a USB 3.0 pci card.

I plugged everything in and installed the drivers and it worked great. However, now, when I turn my computer on in the morning the drive isn't automatically recognized. I have to replug the USB 3 cable into the card for it to be recognized.

If I turn the computer off for a short time period, like 5 minutes or so, then turn it back on, it usually is recognized.

Is there any solution to this kind of problem?

I have the same problem with WD MyPassport 500GB usb 3.0.
Please someone to replay.

If this is an NEC/Renesas USB3 card, try disabling USB 3.0 power management functions with the Renesas Host utility program. Update your USB 3.0 drivers.

If you have the device connected through a USB 3.0 Hub, try connecting it directly.
