Thank you for your time. Actually this package doesn't seem to help more than compiling and installing the source code.
I added the following in /etc/fstab as adviced on /usr/share/doc/midisport-firmware/README.Debian: usbfs /dev/bus/usb usbfs defaults 0 0 I did, in disorder to meet all possibilities, reboot my system, restart udev, replug the device... nothing helps! I can paste here the output of any command (lsusb; dmesg; cat /proc/asound/cards) by request. Notice that I've followed the following tutorial: https://help.ubuntu.com/community/UbuntuStudioPreparation therefore my /etc/modprobe.d/alsa-base contains the following line: options snd-usb-audio index=-2 I suspect we should rather look at the multiple soundcards issue, shouldn't we?
