Forgot to mention, and to add proper Cc. The commit
is this one:

commit a559d2c8c1bf652ea2d0ecd6ab4a250fcdb37db8
Author: Dominik Brodowski <>
Date: Wed Apr 14 21:36:42 2010 +0200

USB: option: add ID for ZTE MF 330

Based on the information provided for by Paweł Drobek, add
a second vendor ID and the correct product ID for ZTE MF 330.

Reported-by: Paweł Drobek <>
Signed-off: Dominik Brodowski <>

Are the IDs really correct? Maybe it's just a typo
after all...

It is interesting that no one noticed this so far.
Or it's just because it's difficult to search for -
"option" is really a bad search term ;)
