OK, a few general ideas again:

Why not wrap board_usb_init() and board_usb_init_fail() into single call. You 
now pass some flags to board_usb_init() already, so just add another for the 
fail case. How does it sound to you?

Moreover, the 'int index' should likely be unsigned int and the special value to 
init all controllers at once should probably then be 0xffffffff
