  I've got a bug report from Randy (Cc) today. And while checking
 it I've discovered a few more things:

  A few days ago I changed my motherboard (now an Asus Z701-A, kernel 4.3.3)
 and it seems that USB3 always fails while testing
 my epsonds driver. All ports, even usb 2.0 ones, are under xhci

 I'm now trying to understand if there's a problem with
 the driver, libusb 1.0 or something else.
