[PATCH] USB: ub 4: Zaitcev's quasi-S/G
Back out Axboe-style quasi-S/G and replace it with one command and
repeated URBs. This is similar to what usb-storage does, only instead
of a few URBs allocated together, one URB is reused.
Jens's idea was very nice, but it collapsed when I had to support
packet commads for CD burning. I cannot issue two or more packet
commands where application expected only one.
However, burning does not work completely yet. The cdrecord starts,
recognizes the device, then aborts without writing a TOC.
