Of note on USB transmission - there are several basic formats. So called 'isochronous' - meaning equal time intervals - is used very often for audio streaming. Unlike formats used for pure data transmission ('bulk' transfer), isochronous cannot report errors and hence has no error correction/re-transmission. So it is possible to have fantastic data transmission but still suffer with real-time transmission.
Fixes to these problems come at various price levels.

Good post.
