Archival checkin of messed-about non-working code to actually read data from
...
disk. Something's wrong with the DMA; requesting a transfer every 2us with a TD
size of 64 bytes is somehow leading to an nrq interrupt every 8us. Mysterious.

You can now transfer gibberish from the FluxEngine to the PC to test bandwidth.
...
On Windows we're getting 620kB/s.

There's a seek command now, which might even work.

Finally figure out the secrets of WCID, so we don't need a signed driver to do
...
raw endpoints. Hurrah! Rip out the CDC stuff in favour of them.

Lots of wasted time trying to make raw endpoints work --- but you can't do that
...
on Windows because libusb can't talk to any device without a signed driver.
Stupid Windows.
Luckily I can get 500+kB/s out of CDC, even on Windows, so let's use that.
