There are constraints that lead to problems. Multiple devices will each have their own clock and so will run at slightly different sample rates, which will lead to regular over-/ underruns. (The USB audio standard defines an option that would allow devices to synchronize to the USB clock, but devices usually don't implement this.) To use multiple devices together, you have to use some utility that resamples the PCM data from/to one common sample rate. Try jack_diplomat.
