I use the USB3.0 single port / double port PCI express card to test.Those work with USB2.0 flash storage,but doesn't work with USB3.0 storage (HDD USB Dock).I guess there are some thing wrong between pcie with xhci-hcd,and there are no error message,no any output from /var/log/message or dmesg...There is an external power plug in the express card device,but after using it ,the express cards still didn't work.
