I think your commit is wrong about UPS_PORT_POWER_SS. - #define UPS_PORT_POWER_SS 0x0200 /* super-speed only */ #define UPS_LOW_SPEED 0x0200 + #define UPS_PORT_POWER_SS 0x2000 /* super-speed only */ #define UPS_LOW_SPEED 0x0200 Now, usb3.0 HDD was not able to recognize. I have USB 3.0 analyzer(LeCroy Voyager), so I can help debug.Received on Fri Jan 13 2012 - 01:41:00 UTC
