4.1 Linux-4.x/Linux-5.4 Gadget 配置示例

4.1.1 小机做 mass storage

dd if=/dev/zero of=/dev/a.bin bs=1M count=100
mount -t configfs none /sys/kernel/config
mkdir /sys/kernel/config/usb_gadget/g1
echo "0x18d1" > /sys/kernel/config/usb_gadget/g1/idVendor
echo "0x0001" > /sys/kernel/config/usb_gadget/g1/idProduct
mkdir /sys/kernel/config/usb_gadget/g1/strings/0x409
mkdir /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0
echo /dev/a.bin > /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/lun.0/file
mkdir /sys/kernel/config/usb_gadget/g1/configs/c.1
echo 0xc0 > /sys/kernel/config/usb_gadget/g1/configs/c.1/bmAttributes
echo 500 > /sys/kernel/config/usb_gadget/g1/configs/c.1/MaxPower
mkdir /sys/kernel/config/usb_gadget/g1/configs/c.1/strings/0x409
ln -s /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/ /sys/kernel/config/
usb_gadget/g1/configs/c.1/
ls /sys/class/udc/ | xargs echo > /sys/kernel/config/usb_gadget/g1/UDC

说明

如果需要增加 lun，在 functions/mass_storage.usb0 下：

mkdir lun.1

mkdir lun.2

4.1.2 小机做 cdrom

mount -t configfs none /sys/kernel/config
mkdir /sys/kernel/config/usb_gadget/g1
echo "0x1f3a" > /sys/kernel/config/usb_gadget/g1/idVendor
echo "0xa4ac" > /sys/kernel/config/usb_gadget/g1/idProduct
mkdir /sys/kernel/config/usb_gadget/g1/strings/0x409
mkdir /sys/kernel/config/usb_gadget/g1/configs/c.1
echo 0xc0 > /sys/kernel/config/usb_gadget/g1/configs/c.1/bmAttributes
echo 500 > /sys/kernel/config/usb_gadget/g1/configs/c.1/MaxPower
mkdir /sys/kernel/config/usb_gadget/g1/configs/c.1/strings/0x409
mkdir /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0
echo 1 > /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/lun.0/cdrom
echo /tmp/phoenixcard.iso > /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/
lun.0/file
ln -s /sys/kernel/config/usb_gadget/g1/functions/mass_storage.usb0/ /sys/kernel/config/
usb_gadget/g1/configs/c.1/mass_storage.usb0
ls /sys/class/udc/ | xargs echo > /sys/kernel/config/usb_gadget/g1/UDC

说明

/tmp/phoenixcard.iso 根据实际情况更改。
