Hello,
On 2014-01-16 I reported a detailed bug regarding this device (or at least a device with same USB vendor/product ID), see https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/1269883 . Tested on different PC, USB2 (ok) and 3 (fail) ports, results are reproducible.
Then I posted to linux-usb list with cc to Freddy Xin (who introduced the driver to the list), see https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/1269883/ comments/ 19 .
It may or may not be the same bug, see comment there https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/1269883/ comments/ 22 .
Hope this helps.
