BBB USB Video status

It appears to me that USB video support on the BBB is broken in a couple of areas:

1) Isochronous DMA mode causes multiple crashes. This can be circumvented by using PIO transfers only.
2) The number of UVC cameras that work reliably seems to be limited to those made by Logitech. Has anyone else had similar experiences?

My question is, who is supporting the TI USB video, so that I can file meaningful bug reports?
