Yes,I have read all the doc on linux-2.6.12\Documentation\driver-model to find
what is driver model, but I can't understand it yet,and can't know how to
remove the driver model for the backport. Could you tell me what documents I
should read more ?

yes,I must not use the old stuff. I analyse the Makefile about gadget, the
Makefile tells me the valuable files are usbstring.c, config.c, epautoconf.c
,omap_udc.c and ether.c . Could you tell me other files or directory should be
included for my backport ?
