May I know what is different between usb 3.0 :smart auto, auto & manual?
For the X10DAi, the default setting for the USB 3.0 Suppport should be Enabled.
Disabled: Force to EHCI mode only, lets you use only usb2.0 in OS
Auto: Recommended when XHCI Pre-Boot Drivers sets to Disabled, require special OS driver support for usb3.0 support
Smart Auto: Recommended when XHCI Pre-Boot Drivers sets to Enabled, require special OS driver support for usb3.0 support
Manual: allows the end-user to configure USB3.0 to USB2.0 mapping.
