The following lines are suspect, looks like that is the usbmidi oss
kernel module:

Again, /dev/midi00 is oss. Which kernel are you booting at this point?
Anyway, you probably want to disable the usbmidi kernel from loading, if
it is being loaded (and that seems to be the case) it will monopolize
the device and then the alsa snd-usb-audio module will not be able to
use it. 

Add "usb-midi" to the list of exceptions in /etc/hotplug/blacklist (that
is, add one line at the end with "usb-midi" in it). 

That should prevent hotplug from loading the oss module.
