When usb_hub_reset_devices is called, it should be passed both an
indicator which hub it should operate on and what port number (local
to that hub) should be reset.
Previously, the usb_hub.c code did not include such context and
always started resets from port number 1, performing multiple
reset-requests for the same devices:
/*
* Reset any devices that may be in a bad state when applying
* the power. This is a __weak function. Resetting of the devices
* should occur in the board file of the device.
*/
for (i = 0; i < dev->maxchild; i++)
usb_hub_reset_devices(i + 1);
This adds an additional 'hub' parameter to usb_hub_reset_devices
that provides the context to fully qualify the port-number in.
Existing implementations are changed to accept and ignore the new
parameter.
