based on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358871/comments/7 I tested with the HDD enclosure IcyBox IB-351 series with USB 3.0 connection with the same result (connection drops after 300 MB reading, error message "xHCI xhci_drop_endpoint called with disabled ep" occurs sometimes, other devices (e.g. Samsung HD103SI 1 TB HDD connected with 3.0 USB adapter to eSATA of enclosure) read hundreds of GB before failing, but definitely do before reading 1TB).
Also confirmed on Lenovo IdeaPad-Z500 after BIOS update to 71CN51WW(V1.21) (changelog didn't indicate any USB issues anyway).
The issue seems to cause failure of ASIX AX179 gigabit ethernet chip as well, but is independent from the usage of the ethernet adapter.
I'm without any clue and stuck with an unreliable USB and ethernet connection which basically means no I/O out of the machine!!
