Roland and Edirol devices
UX256 (product-specific support)
Others Other Yamaha MIDI devices will be attached and are expected to work also.

SND_UAUDIO(4) BSD Kernel Interfaces Manual SND_UAUDIO(4)NAME
snd_uaudio -- USB audio and MIDI device driver
To compile this driver into the kernel, place the following lines in your kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
The snd_uaudio driver provides support for USB audio class devices and USB MIDI class devices.
A USB audio device consists of a number of components: input terminals (e.g. USB digital input), output terminals (e.g. speakers), and a num-
ber of units in between (e.g. volume control).
Refer to the 'USB Audio Class Specification' for more information.

The snd_uaudio driver first appeared in FreeBSD 4.7.
This manual page was adopted from NetBSD 1.6 and modified for FreeBSD by Hiten Pandya <hmp@FreeBSD.org>.
The PCM framework in FreeBSD, as of this writing, does not handle device un-registrations in a properly abstracted manner, i.e., a detach
request is refused by the PCM framework if the device is in use. It is necessary to allow the device un-registration to complete success-
fully, otherwise the PCM layer will panic.
