thx dave
When i use g_zero instead of file_storage,i get the host mesg is:
hub 1-0:1.0: debounce: port 8: total 1500ms stable 0ms status 0x0
hub 1-0:1.0: connect-debounce failed, port 8 disabled

What it means?It means my bus enumeration is right?
Besides,i met another problem:
I find when i do set_configuration,the set configuration execution is
delayed,that causes my USB_BULK_GET_MAX_LUN_REQUEST can't be executed
rightly(as fsg->config is 0 ).And the clear halt for ep1(
CLEAR_FAETURE)is not right either.Then,i get "fsg full speed config #1"
that means the SET_CONFIGURATION is right.but then,the host would not
send USB_BULK_GET_MAX_LUN_REQUEST any more.However,at that time,the
file_storage thinks the bus enumeration is finished,it begins to do scsi
command,and attempts to read my ep1_out,my ep1 fifo's data is not right
then.
That's my thinking for it,is it right?
if it is right,then how can i let set configuration finish before the
host sends USB_BULK_GET_MAX_LUN_REQUEST command?
