For reference the UCA202 draws up to 200mA so on modern PCs, it should not be an issue. It tends not to be an issue except on low-end or embedded systems. Powered hubs have their own gotchas, naturally - a better approach if you have spare PCI/PCIe slots is to add USB PCI/PCIe cards, which will draw power directly from the PSU on the PC. I've yet to have to do this for anything, though. fwiw, I've had good experiences with the UCA202 for the low-end side of things, and would recommend them (possibly the only Behringer product I'd ever recommend to anyone). They're dead simple bits of kit, just an USB audio codec chip and the appropriate support circuitry. And yes, Rivendell will play fine with multiple cards - they show up as different cards in ALSA. You do have to be a bit wary of power-on ordering/having the same card mapped to the same ALSA device number each time but I think it's pretty solid these days if you're not constantly replugging, and even then you can do some udev hackery.
