I have a WD Passport WDBACY5000ABK. Whenever I plug it into my front USB 3.0 headers, it connects and then disconnects over and over again repeatedly, typically not long enough for it to be detected in Windows 7.
I tested it on another motherboard and it does the same thing. Other devices work in the front USB 3.0 headers as well so I don’t suspect them to be the issue.
I’ve updated the Passport to the most recent firmware, and I’ve installed the SES Driver.
I’m not sure what else to try, but if anyone has any suggestions please let me know.
