Thanks for initiating this! I have one comment on the text:

Quite a while ago when Line6 noticed that a Linux driver is being developed 
for their hardware, they contacted me (yes, the other way round :-), and I had 
a brief conversation with a developer who provided some useful information. 
Unfortunately this guy doesn't seem to work at Line6 now, at least I didn't 
get a response when I tried to contact him again later.

One thing he was curious about is how I found out the protocol by which host 
and device communicate with each other. He told me that it's ok for them if we 
use USB analyzing tools to observe the traffic (which is what I did), but 
reverse engineering the driver by inspecting the machine code is prohibited by 
the Line6 software license. Though the term "reverse engineering" is somewhat 
ambiguous, it might trigger undesired emotions in the context of asking for 
help :-)

I don't know if you can alter the ticket, but if you can, it might be a good 
idea to make clear that we didn't violate their license.
