i got the same issue (http://support.plugable.com/plugable/…)
with plugable laptop card and seagate go flex 1TB (with 3.0 usb cable)
i have HP PROBOOK 4530s
The seagate works fine with 2.0 ports, but when i plug the express card and attach the power cable(to one of the 2.0 ports) that came along with it, it does not show up. my seagte beeps continously after which the LED on seagate keeps flashing.
Tried 2.0 pen drive with this card which works fine but not the external seagte. Everthing seems to be fine in the device manager. I waited 3months for this from my dealer only to know that there is some stupid firmware issue . why has not this been FIXED yet???
