Curiosity, NO. Dies almost immediately when run at USB 2.0 Hi-Speed. With a USB 2.0 hub, with a USB 2.0 port on a USB 3.0 hub, and with a USB 2.0 extension cable in place of a hub. Near instant hangs. Plugged directly to the USB 3.0 port, it works fine. -- Mark Lord Real-Time Remedies Inc. mlord@...ox.com -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
