yes, the first patch could solve the problem with pid 0xfffe.

yes, the second path i had been tested and it works fine.


In you other two mails, you want to modify the line-coding handling, but i'm 
not sure that have some problem.
otherwise, it will be have some problem in the pid  of 0xfffe for our 
company(the pid of 0xfffe belongs our company).
i suggest you sould move the pid of 0xfffe from zte_ev.c to option.c at first 
and then modify others.


i don't know why create the file of zte_ev.c that is not necessary. i suggest 
we can move all the pid from zte_ev.c to option.c.
