It's possible that when your EHCI driver was loaded, it interfered with other devices already being managed by the OHCI driver. There are other possibilities too, however. It would be easier to tell what happened if you turned on usb-storage verbose debugging in your kernel configuration. > ... > usb 3-1: device not accepting address 2, error -110 > ... > I think this is the line, which causes that the mass storage device does not > work. the lspci output is the same as in the first mail. Why do you think that? At the end of your log, usb 3-1 connects using address 4 and is found to be a hub, not a mass-storage device.
