We used to initialize USB peripheral and driver here.
According to my tests this is way too late. The USB peripheral
therefore does not have enough information to start responding to
USB host request, which causes very slow USB device recognition,
multiple USB device resets, etc...
If we want to change the USB profile, the procedure is simple:
* USB cable must be disconnected
* call usbDeInit();
* call usbUnit(); which initializes USB with the new profile.
Obviously the usbInit() should be modified to have a runtime
selection of the USB profile.
