I don't think that you can seperate the issues.
Either the driver owns the urb during the callback or it doesn't.
If you own the urb, you may certainly free it.
However, we must be able to unlink an urb even while the
completion handler is running, else we race with every
completion handler that resubmits its urb.
Yet we must trust the urb pointer to be valid to do an unlink.
IMHO freeing an urb in the completion handler is asking for trouble.
