Nothing wrong here. It is the same with any USB midi device. I have:
$ cat cards

4 [UM1G ]: USB-Audio - UM-1G
Roland UM-1G at usb-0000:00:1a.0-1.4, full speed
But:
$ ls UM1G
id midi0 usbbus usbid usbmixer
This shows that this device is a midi device.
A USB device with audio looks like:
$ ls Device
id pcm0c pcm0p stream0 usbbus usbid usbmixer
notice the two sub directories: pcm0c pcm0p which show this device
has one capture device (pcm0c) and one playback device (pcm0p).
so what do you see when you do:
:~$ ls /proc/asound/KONTROL49
id midi0 oss_mixer usbbus usbid
oss_mixer looks suspicious…
Greets!
