HI All,

  when I do plug in/plug out tests for USB1 of IMX28,The usb1 controller maybe enter suspend mode sometimes.

  The value of HW_USBCTRL_PORTSC1 register is 0x1C804800 or 0x18038A81 when this issue occurs.I must power on the PCB board again,otherwise the usb1 can't work any more.

  This issue may often happen in attach process.
