My apologies for blindly forwarding someone else's answer instead of
looking it up.  URB status codes, like most kernel responses, are errno
values.  -2 is ENOENT, which generically means something was not found. 
In this case, the generic kernel USB driver looked up endpoint ordinal 2
in its list of "output" endpoints, and there was no such entry.  ENOENT.
