through 550 paracord, hard. There is no way to do it without cutting, and reconnecting the usb. The closest I got to getting one to work was when i didn't even solder the wires, but just twisted them and taped them. It worked up until i had to do a little fidgeting to get the paracord over the joined part, at which point I guess I broke one of the connections. I've ruined like three usb cables trying to get 550 paracord over them. I've made two wrapped in techflex (one double wrapped) with no issue. you just have to shave the plastic off the mini end for it to fit over without cutting the cable.
YMMV though.
