this is my problem:
My Sandisk Extreme 64Gb USB Falsh Drive _ Don’t work _ If it’s plugged in to the USB 3.0 ports controlled by the chipset (AMD A75 FCH, Hudson D3), it’s too slow, like USB 2.0 pedrive.
If the pendrive it’s plugged in to USB 3.0 controlled by ASmedia or NEC uPD720202 work fine.
Thanx
Mauro
