Reading tested with `dd`, `gpart` and `btrfsck`. Also confirmed on Lenovo IdeaPad-Z500 after BIOS update to 71CN51WW(V1.21) (changelog didn't indicate any USB issues anyway). Also confirmed with 3.16.3 and 3.16.0-14 on Ubuntu 14.10-beta1 after updates. 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!!
