Loading usb (card) drivers (snd-usb-audio) works just fine, and the patch doesn't change the behaviour regarding card drivers. The problem is that the sequencer driver (snd-usb-midi) isn't loaded when the card driver has been loaded. > We definitely don't want to see thousands of failure messages in > /var/log/messages. snd_seq_device_load_drivers() has its own protection against multiple request_module() calls (the DRIVER_REQUESTED flag), so this isn't a problem.
