int usb_hcd_msp_probe	(	const struct hc_driver *	driver,
		struct platform_device *	dev
	)

usb_hcd_msp_probe - initialize PMC MSP-based HCDs Context: !in_interrupt()

Allocates basic resources for this USB host controller, and then invokes the start() method for the HCD associated with it through the hotplug entry's driver_data.

void usb_hcd_msp_remove	(	struct usb_hcd *	hcd,
		struct platform_device *	dev
	)

usb_hcd_msp_remove - shutdown processing for PMC MSP-based HCDs : USB Host Controller being removed Context: !in_interrupt()

Reverses the effect of usb_hcd_msp_probe(), first invoking the HCD's stop() method. It is always called from a thread context, normally "rmmod", "apmd", or something similar.

may be called without controller electrically present may be called with controller, bus, and devices active
