Thanks!
That board is your problem, it only provides 500ma per usb port. As you can see in my post above, the MLD's easily go over 2 amps!
Brilliant thanks could you please point me towards a decent usb hub thanks
Be sure to get that model with the inbuilt fan. It'll certainly prolong life span, usability + then you are sure you have the high powered version. They also come without fans but those then have 500ma-1000ma per port with 2 fast ports.
