setusbconfig mass_storage可以配置两个存储设备都挂载到USB上吗？

也就是通过setusbconfig，可以同时在PC上看到SD卡和UDISK吗？
[ -d /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0 ] || {
mkdir /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0
echo Tina > /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/lun.0/inquiry_string
}
ln -s /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/ /sys/kernel/config/usb_gadget/g1/configs/c.1/f1

• echo "/dev/mmcblk0p1" > /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/lun.0/file
  echo "/dev/loop0" > /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/lun.0/file
