I have a (UK) Rock laptop - effectively a Clevo 570MTU laptop, running W 7 64-bit, with SP 1.
I recently installed a Startech USB 3.0 ExpressCard, with Renesas/Nec drivers updated to latest version.
The ExpressCard shows up in Device Manager as USB 3.0 Host Controller and USB 3.0 Root Hub, with no errors.
I purchased a Western Digital ("WD") My Book Essential 2TB USB 3.0 and 2.0 external drive for back-up of the laptop.
I have tried numerous ways to do this but, as yet, I have not been able to get the WD to be recognised on the laptop AT ALL through the USB 3.0 ExpressCard.
The WD Does show up, and work (slowly) when connected to the laptop's USB 2 port.
Likewise, USB 2 devices work when connected to the USB 3.0 ExpressCard.
This is madness and maddening - why will a USB 3.0 device not work with a USB 3.0 port???
