As I said earlier, the delay was put *before* most of the data gets written.

More specifically, I inserted a delay of one second between transmission of
magic1 and magic2, one between magic2 and magic3, and one between magic3 and
the first firmware file.

If I additionally insert a one-second delay before the fd is closed, I get
this usbmon log:
http://stuff.onse.fi/gobi2000/gobi-regression5.mon.log

The firmware upload is still unsuccessful.
