First two bytes are 0 and 194, so that 0 is being removed and re-added

I think that's what I did.. In process_hid_report I'm printing an hex string of
the report buffer. Using this table
http://www.hhhh.org/~joeboy/resources/magcards/trackdata_ANSI-ISO_ALPHA.html I
can see that the data in that buffer is what's supposed to be on the magstripe
(with the addition some bytes at the beginning and some bytes at the end). And
yes the content of that buffer changes when I swipe a different card.
So it looks like the data is sent by the reader back to the application, but
the application keeps waiting like nothing happened.
