In my Debian image the line you want to modify is:
modprobe g_multi file=${gadget_partition} cdrom=0 stall=0 removable=1 nofua=1 iSerialNumber=${SERIAL_NUMBER} iManufacturer=Circuitco iProduct=BeagleBone${BLACK} host_addr=${cpsw_1_mac}
以及在此之前设置的相应$gadget_partition变量，以自定义要显示的文件夹.
and the corresponding $gadget_partition variable that is set just before that in order to customize the folder you want to expose.
请注意，标准配置中的g_multi小工具具有3种不同的设备:以太网接口，大容量存储外围设备和串行接口.如果要自定义参数，可以参考
Note that the g_multi gadget in its standard configuration presents 3 different devices: an ethernet interface, a mass storage peripheral and a serial interface. If you want to customize the parameters you can refer to the g_multi documentation
