Now,i use "stall=n" option when i load g_file_storage. If load "stall=y",there are some errors. If i leave only DEBUG, VERBOSE, and DUMP_MSGS,there are too many debug message during the data transfer.And my error only happens each several hours.I try open above DEBUG options,if the host resets device,just repeat below debug message: g_file_storage gadget: bulk_out_complete --> -104, 0/31 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 g_file_storage gadget: sending command-failure status And there is an error at check_command function per above message. It is unit_attention_data=SS_RESET_OCCURRED;And the check_command returns -EINVAL; > Alan Stern > > ------------------------------------------------------------------------- Using Tomcat but need to do more?
