M-Audio (USB audio interface)
Mint (older version)
KeyStudio 49i is an USB MIDI Keboard, It works perfectly and no latency on audio.
What was done to make it work:
Use the package manager and look for midisport package.
These packages allow you to use M-Audio's USB MIDI and Audio interfaces with Linux. These devices require a firmware download before an operating system driver (e.g. ALSA's snd-usb-audio) can access them.
