Probably a bad printf format.  I'll take a look, and I'm sure that one 
will be easy to fix.  The oops listing unfortunately looks mostly 
useless, but I'll poke around.

The assignment of USB address is done by the USB core, and it is normal 
to see it advancing each time the device is detected.

As for the -75 status that's EOVERFLOW which is something I've *NEVER* 
seen before.  What's more you have it coming from code which has been 
unchanged and stable for multiple years.  So right now I do not know 
what is going on here.  My first impression is that a bad call is being 
made into the USB core at this point but as I said the code in question 
is rock stable, unchanged for a very long time.  I need to look at it to 
see possible sources for that error code.  I will likely have some more 
questions / tests for you there.
