ADB over USB doesn't work on Origen

Not working on https://android-build.linaro.org/builds/~linaro-android/staging-origen-11.10-release/#build=1

Not working on https://android-build.linaro.org/builds/~linaro-android/staging-origen-11.10-release/#build=1 dmesg of plugging in adb attached.

The landing team has USB host, gadget and device working.

What other kernel side interfaces are needed for ADB ?

Are there specific kernel options that need enabling ?

Not working on:

https://android-build.linaro.org/builds/~linaro-android/staging-origen-11.10-release/#build=5

The trick here is to enable USB_G_ANDROID, the only way to find this is if you search the drivers directory for a file named f_adb.c there's no reference to ADB in the kernel config.

USB_G_ANDROID is only available if your gadget devices are built into the kernel it will not show up if if they are built as modules. Is there a good reason for this ?

After applied Angus's latest kernel updates, it works on the latest staging-origen build, refer to this: https://bugs.launchpad.net/linaro-android/+bug/888647

I copy the procedures here:

######################################################
I did not take care of user-space adb initialization. It works fine after running following commands from android console.

# echo 0 > /sys/class/android_usb/android0/enable
# echo adb > /sys/class/android_usb/android0/functions
# echo 1 > /sys/class/android_usb/android0/enable

Reconnect the usb cable after running these above commands. You will see the following message on android console.

"android_usb gadget: high speed config #1: android"
######################################################

Pushed a patch for review http://review.android.git.linaro.org/#change,814 which does the adb user space initialization from init.origen.rc

Change 814 has been merged, but I still can't get the correct information about the Origen board which I connected to my computer:

noname@noname-pc:~$ adb devices
List of devices attached
???????????? no permissions

And I can't launch the ADB shell either:

noname@noname-pc:~$ adb shell
error: insufficient permissions for device

I tried to kill the ADB server and restart it, the error message is same.

The build I used is #46 on our Android build platform which contained the changes we made.

Thats weird. I have seen this "no/insufficient permissions" error number of times and "sudo adb kill+start server" solves it every single time for me. Did you get "android_usb gadget: high speed config #1: android" message on Android console (minicom)?

I got the points:

1. ADB must run with the root permission, which means "sudo adb devices".

2. If the USB cable is connected before board powered up, ADB won't work, you have to plug it out and plug it in after the board boots up, then you will see these 2 lines:

<6>android_usb gadget: high speed config #1: android
android_usb gadget: high speed config #1: android

After that, run the ADB on host computer, it works.
noname@noname-pc:~$ sudo /home/noname/programs/android-sdk-linux_x86/platform-tools/adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
0123456789ABCDEF device

And ADB shell also can be launched successfully:
noname@noname-pc:~$ sudo /home/noname/programs/android-sdk-linux_x86/platform-tools/adb shell
# pwd
/

But for my HTC Sensation phone, I don't need run ADB with root permission:

noname@noname-pc:~$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
SH17GV804706 device

ADB over USB only work 1 time:

https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc47-samsunglt-stable-blob-12.05-release/#build=6

After plug in the USB cable, then do the "sudo adb shell", then the device serial number can be shown. But once exit the shell, then the ADB connection can't be established again.

ADB install doesn't work either under the USB mode.

>once exit the shell, then the ADB connection can't be established again.
if you exit from the adb shell, please unplug USB cable and then plug it again before you run ADB again.

Tried that, but after it, it still only works once, and the ADB install doesn't work either.

Ok let me reproduce this scenario.

The ADB over USB works again, it possibly depends on the USB cable quality.

Summary:
it seems to have some relation to the USB OTG cable, It is higly
recommended to use the high speed shield USB cable.

For example, with some cables (USB OTG), it requires plug/unplug eveytime PC host is connected to Origen board
Or worse case, it is not work after running a few time, which is reported by Botao.

With the good shield cable, USB OTG hence ADB works fine with Origen even withoug plug/unplugging.
