I was able to get 4 cameras running at 45 fps by limiting the bandwidth (right click on cameras and select Bandwidth Manager) to 190. This ran a good number of 30 second trials and only errored once. This suggests the current USB bandwidth limit is ~750 MB/s, so we can use that for testing for now.

However, the actual recording drops frames when running at 45 fps. It seems much more bandwidth is needed for the actual recording, or there's another limiting factor in the pipeline from camera -> disk.
