Maybe we should just use those terms, then :) About the booting issue, I double-checked the logs of what happens when the device is plugged in with a USB2 cable into a USB3 port, and yes, there is nothing unusal save for a single dmesg line that stands out: xhci_hcd 0000:00:14.0: device LPM test failed, may disconnect and re-enumerate But it can be seen and mounts fine. I'll check usbmon a bit later. -- 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
