In Lubuntu 14.04.2, kernel 4.2.0-32-generic #37~14.04.1-Ubuntu SMP it's still problem. Yes, I have laptop with usb 3.0, and xhci_hcd driver. All configs is good, running from root allows scan sometimes, after 3-4 tryes with xsane, simple-scan don't see anything. Please create new thread yourself, I don't know where do it.
