Subject: In packet master, move USB flush from packet thread to echo thread
X-Git-Tag: debian/0.6+27+gb0d7e3f~18
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=bc62bb254085cc705203b57260c04ac5e14c6611

In packet master, move USB flush from packet thread to echo thread

This keeps the packet thread from blocking on USB and also makes the
flush happen after every packet (slightly more USB traffic, but
packets are slow anyway).
