Hi, Is it necessary to use xHCI driver for USB 3.0 host controller? I am trying to support Transdent PNU3 (having usb 3.0 controller) in my h/w running 2.6.16 kernel. Is it not possible to use other legacy host controllers (ohci/uhci/ehci) already available in 2.6.16 kernel ? Will usb 3.0 not fallback to usb 2.0 with legacy drivers ? I do not want to put my effort back-porting xhci to old kernel until it is absolutely necessary. thanks... -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
