thx,Alan. Now,i understand what i need to do.
At last mail,u told me don't need to change any code of file_storage.c but: 1.How about same descriptors(usb_device_descriptor, usb_config_descriptor............), and fs_bulk_out_desc,fs_bulk_in_desc? I keep it or change to my config? 2.there is not my chip in usb_ep_autoconfig function, i still need to use it?
