You don't need any MIDI cables to run MIDI through a recording interface to your computer. MIDI is just code and it can be passed through MIDI cables (one way) or two way (in and out) through a USB cable.
So hook a USB cable from your interface to your computer and another USB cable from your keyboard to our computer and you're good to go. No MIDI cables.
The only time you need MIDI cables is if you want to interface some older, pre-USB gear (that only has MIDI jacks and no USB jack) with your system.
