When I plug my USB 3.0 phone into one of the Intel USB 3.0 ports (USB3_2_3), it connects properly and reports it's in USB 3.0 mode. But when I plug the phone into one of the ASMEDIA USB 3.0 ports (USB3_01), it doesn't connect at all, not even in USB 2.0 mode. However, USB 2.0 devices work fine when plugged into the USB3_01 ports.

Z77 Extreme4, BIOS and drivers up-to-date, Windows 7 x64 SP1 (all updates installed). BIOS USB settings are all at default values. FastUSB utility is not installed.
