dear linuxfoundation:
Because of the usb driver parameters error that leads to failed in
reconnect. now i want to modify the error parameter and
move device pid fffe from zte_ev.c back to option.c for our company.
modify reason:
1. Move device pid fffe from zte_ev.c back to option.c for our company.
2. Modify the parameter from 0x0003 to 0x0000. the problem may cause the device
can not be close.
these two points are in the patch, please submit it for me. thanks.
