Running two cameras without taking pains to limit these allocations, you are certain to have trouble. If you can't find any detail on how to do this online, PM me and I'll contact the mentors to find out how we resolved/mitigated the issue.
USB bandwidth? There is no problem with running two cameras at a time, in regards to the roborio.
