Hi,

Hi,

I am looking for a way to limit which usb host interfaces are initiali- zed by usb_init() in order to skip unused interfaces. This is currently governed CONFIG_USB_MAX_CONTROLLER_COUNT, which is possible to redefine at the board level. However this doesn't cover more complex cases where a SoC has multiple host interfaces but a board using that SoC only uses a subset that is not necessarily contiguous.

Does there currently exist a way to define such behavior, or should the functionality be added to usb_init() to support this?

The driver model should allow you to do exactly that, though I don't know if it's supposed on the MPC85xx .

Thanks. Matthew Bright
