BOOL usbh_ehci_hw_port_power (
  U8   ctrl,
  BOOL on
);

The usbh_ohci_hw_port_power function is used for supplying or removing power on the EHCI USB Host controller ports. The argument ctrl is the index of USB Host Controller. The argument on specify if function should do power on or off of the ports. This function should be adapted if EHCI is not used for driving power but power driving is manual by GPIO pin for example.

The usbh_ehci_hw_port_power function is part of the RL-USB Host software stack.

You can modify this function to suit different EHCI controller hardware. This function will need to be changed if EHCI controller is used on a chip that does not yet have a low level driver provided.

The usbh_ehci_hw_port_power function returns one of the following manifest constants.

• __TRUE
  Success.
• __FALSE
  Indicates that the port power driving has failed.
