Though better would be to not refuse IN transfers if an OUT ep isn't available and vice versa - the sound card might support only either Playback or Capture, it doesn't have to always support both. The rbuf should have been allocated only for ep that exists. So I think, while this patch prevents potential null-pointer dereferencing it also weeds out the "simplex" capability of the driver.
But if you have on out ep or only in ep you have to update your descriptors and this has not been done.
Thanks.
