That looks normal.
The DONE transaction transferred the SETUP packet, but still lists frame [0],
but is not dumping the data, because it has already been sent. frame [0] is
always the SETUP packet for control endpoints.
So where should I dig further to find out why the read at 09:28:44.885162 shows
only
'e:' from the string, shown completely at 09:28:47.463632 (2nd block) ?
