USB Port not working

[mamo77]

Hi All -

I recently added a Silverstone FP59 USB port/card reader. After updating my MB drivers (MSI Z77A-G43), it will now power and charge devices but they do not appear in Explorer. Windows 7 64 bit.

can you roll back the drivers. There's a review on Amazon that says the same as what happened to you...
