    OpenUSBByName(): add some low level debug
    
    Log the bus_number, device_address, idVendor and idProduct of the
    current libusb device in the loop.
    
    This debug is mostly useful on Mac OS X since the idVendor and idProduct
    of the searched device is _not_ given in the device name.
