Having owned this for about 5 or 6 years and having done precisely zero recording with it in that time, it's time for it to find a more appreciative owner, I think. I've owned it from new, but no longer have the box or instructions (online link to those here: https://www.tascam.eu/en/docs/US-1x2_RM_vA.pdf).
I don't think it came with any leads in the first place, but if it did they too have vanished into the ether. It's phantom powered anyway, so there shouldn't be any issues when its properly connected. I say I didn't record with it, but I actually did use it to experiment (not too energetically) with Garageband and a couple of other free version DAWs, and it worked fine. It's a very simple AI and may be of interest to someone wanting to dip their toes into some home recording. Price includes delivery within the UK. Thanks.
