If the request was cancelled,the copy is aborted or not?
If the software is pretty ok,it can go on copying after
we receive bulk_out_complete --> -104.

My debugging log sequence is:
Receive a error CBW:
0: 00 1e 45 ff 00 00 02 00 08 00 00 00 80 00 0a 25
10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Then the host send reset 8 times(WindowsXP),every reset,my log is:
g_file_storage gadget: reset config
g_file_storage gadget: reset interface
g_file_storage gadget: set interface 0
g_file_storage gadget: full speed config #1
At the last reset:bulk_out_complete --> -104, 0/31 will appear first.
then go on above log.
