That's confusing. What instrument did you pluck in the first few seconds of the video? Your Les Paul? Did you use the same cable for the bass as whatever you played in the first few seconds?
It's not really possible to have an incompatibility between guitar and interface. It's just an electrical signal no matter what pickups or guitar you use. There CAN be an incompatibility between signal LEVELS between devices - LINE level, MIC level and INSTRUMENT level. All electric guitars/basses output at INSTRUMENT level and most interfaces - yours included - have the ability to input INSTRUMENT LEVEL (as well LINE and MIC level). But I don't think that's the issue here either.
Fact that the interface isn't registering a signal on the bass, I'm narrowing down that the problem is something between the pickups and end of the bass cable (the end you plug into your interface). Could be a bunch of things.
I come back to the battery - is it a fresh battery and is it installed correctly? If you're not using the same cable for the instrument in the first few seconds of the video, do you know if the cable you used on the bass is good? If neither of those seems to be the culprit, you're into the electronics in the guitar - wiring, components from pickup through controls to output jack.
Did you buy this bass new or used?
