The usb controller does not manage correctly the suspend mode for the ehci. In echi mode, there is no way to suspend without any device connected to it. This is why this specific control is added to fix this issue. Since the suspend mode works in ohci mode, this specific control works by suspend the usb controller in ohci mode. This specific control is by setting the SUSPEND_A/B/C fields of SFR_OHCIICR(OHCI Interrupt Configuration Register) in the SFR while the OHCI USB suspend. This set operation must be done before the USB clock disabled, clear operation after the USB clock enabled.
