在 Linux-3.10 上使能 USB ADB
编译内核时使能 USB FunctionFS
When building your kernel, make sure to configure in FunctionFS:
Device Drivers -> USB Support -> USB Gadget Support
-> USB Gadget Driver -> Function Filesystem
设置正确的 USB vendor ID 和 Product ID
这个设置可以放在 bootcmd 或者加载内核模块的时候通过参数传递：
Modify your boot parameters to set the vendor and product ids so adb on your host recognizes the device.
g_ffs.idVendor=0x18d1 g_ffs.idProduct=0x4e26
Alternatively this can also be done if you built the gadget driver as a module at load time:
insmod g_ffs.ko idVendor=0x18d1 idProduct=0x4e26
启动 Android 并挂载 functionFS， 使能 USB adb
Now here I‘m assuming you‘ve got a serial port working. Boot your target device with your new kernel (and insmod the g_ffs driver if necessary), and setup the functionfs directory:
# mkdir /dev/usb-ffs
# mkdir /dev/usb-ffs/adb
# mount -o uid=2000,gid=2000 -t functionfs adb /dev/usb-ffs/adb
重启 adbd 守护进程
If everything is working, you can kill adbd and when it restarts it should find the functionfs mount and make use of it.
# ps adbd
# kill <pid for adbd>
然后进入 cmd 或者 Linux Host 就可以成功连接 usb adb 获得 Android shell 了
On your host system, connect to the target using the adb program:
$ ./adb shell
root@android:/#
Hooray there‘s your shell!
