USB 3.0


Having a problem with the USB 3.0 ports on my M17x R4. They seem to be recognised and running as USB 2.0? as far as I can tell all drivers are up to date, but when I plug my Integral USB 3.0 memory stick it recognises it as usb 2.0 and gives the usual message saying it can perform faster if plugged into a USB 3.0 port?? i'm confused, any ideas?

Edit: actually it recognises the drive as USB 3.0 but seems to think its plugged in to USB 2.0 port?
