USB Host Diagnostics determines your device's USB host capabilities.

USB host is a very powerful feature of recent Android based smartphones and tablets, but on many firmwares (both stock and custom) the feature is somewhat broken.

For example, at launch the Galaxy Nexus told all the apps and the Market that it supported USB host, but USB host did not actually work (this was fixed in the Android 4.0.2 update). This broke several apps.

That is just one example of many. There are even cases where OEMs advertise USB host support, but the device does not support it at all. It appears as if USB host support isn't tested by Google or the OEMs when they push out new firmwares and devices at all.

As we cannot depend on Google or the OEMs to correctly provide information regarding USB host support, and the Android framework will regularly lie about it to both the Market as well as Android apps, this application was created so you can test your device's USB host capabilities for yourself.

If you allow it, the app will also submit your results to my website, so together we can create a complete database of devices and firmwares and their USB host support.

This tool may also come in handy for those porting firmwares.

Requirements:
- Android 2.3.1 or newer
- (Optional) Root
- USB OTG cable (unless your device has a fullsize USB port)
- USB memory stick, or another USB device to test the connection with

The result database is available here:

Shows enumerated usb devices, and allows you to mount external mass storage devices to the filesystem. Supports advanced features like the ability to reload partition tables and reseting USB devices. It can also control the USB Host functionality of S5PC210 devices with the appropriate kernel patch (more about this later)

The application does not use the USB Host API, so it can also run on older, 2.x devices. Because of that however almost all functionality (except for the listing of USB devices) requires root (superuser) access, and a recent version of busybox installed!

The application needs a device that has USB Host (or USB OTG) functionality. Most modern high-end devices have this ability. Check the documentation and specification of your device (this functionality is usually called USB OTG or USB Host)

If your device doesn't have native USB OTG functionality, there are kernel patches for some older devices to enable the functionality, most notably for:

- S5PC210 (Hummingbird) based Samsung phones (Galaxy S, Captivate, Nexus S)
- QSD8250 (Snapdragon) based HTC phones (G1, Nexus One, Desire, Incredible)

You can find appropriate kernel drivers for these phones here:
- Hummingbird / Samsung phones: http://forum.xda-developers.com/showthread.php?t=1450298
- Snapdragon / HTC phones: http://sven.killig.de/android/N1/2.2/usb_host/

Note that these drivers might require skills to install, and may damage your phone and void your warranty!

The app. detects and offers solutions to issues around USB Host and OTG cables. THIS SOFTWARE WILL NOT MOUNT OR SHOW THE FILES ON A USB DRIVE. It verifies your OTG cable is good and that Android can see the USB device. Other software may be required to see the files.

Usage:
1. Disconnect your OTG cable when prompted.
2. Connect your OTG cable when prompted.
3. If everything is OK, you will get 4 green check marks. If nothing happens or you get less than 4 green checks, tap More Info (Web) for a description of the problem.

Software can not overcome a hardware limitation. If your device does not support OTG, nothing will happen when you connect the cable. Please do not write a bad review because your hardware does not support OTG! If your device does support OTG and it is not detected by this software, please contact me via the "Email Developer" link.

Required hardware:
1. An OTG cable
2. A flash/pen drive, card reader or camera.

Automatically mount and dismount USB sticks on various devices like the Galaxy Nexus, Nexus 7 and Nexus 10. The Nexus 4 is not supported - this is an issue with the device, not with StickMount !

!!! REQUIRES ROOT !!!

Various Nexus and "stock Android" devices do not automatically "mount" mass storage devices (such as USB sticks). StickMount has been made to solve this problem, and give you access to the files on your USB connected storage from all your apps.

StickMount is known to work on many devices, but is built *only* with *Nexus* devices in mind.

Once StickMount is installed and you connect a USB stick with a "USB host / OTG cable", the device will show you a popup if you want to open StickMount. It is advised to tell the device that you want to do this by default.

If you have just installed StickMount and you already had a USB stick connected, you must manually launch the program, or disconnect/reconnect the USB stick for StickMount to start working.

Mass storage devices are mounted to "/sdcard/usbStorage/xxxx/".

----- (Pro) Kill apps preventing unmount -----

Sometimes an app has a file in use located on the USB device, and won't let go of it. This can prevent StickMount from unmounting the USB device. It will seem like the device stays connected (this is harmless). StickMount Pro provides an option that attempts to kill (terminate) all the apps that are preventing the unmount from succeeding.

----- (Pro) Media scan -----

StickMount Pro supports triggering the media scanner on each (un)mount action. This will automatically make the files on your USB device available in apps like Gallery and Music. Please note that the media scanner is not a visible process on all Android devices - it might actually work silently in the background without any visual cues. It may take a minute for your files to show up, so don't panic if they don't show immediately.

Even if you have this option enabled, you can prevent folders from being scanned by placing an empty file called ".nomedia" in that folder. If you put it in the root of the USB device, the entire device will not be scanned.

----- (Pro) Mount as partition label -----

Instead of using the block device name for the partition, use the partition label as mount name, falling back to uuid or block device name if the label is unavailable.

----- (Pro) Create symbolic links -----

Create symbolic links in /mnt and /storage to the actual mounts in /sdcard/usbStorage/

----- Filesystem support -----

The filesystems supported depends on your device firmware. On most devices, at least vfat/fat/fat32 and ext2/3/4 are supported. On the latest Android versions, ntfs is also supported in read-only mode. Some devices also support exfat out the box, but most do not.

StickMount can utilize the "ntfs-3g" and "mount.exfat-fuse" binaries to add support for ntfs (untested) and exfat, but these are not included. If you place the "ntfs-3g" or "mount.exfat-fuse" files in the root of your internal storage ( /sdcard ), StickMount will automatically use them.

You can find the needed files here:
ntfs-3g: http://forum.xda-developers.com/attachment.php?attachmentid=1145436&stc=1&d=1340293802
mount.exfat-fuse: http://forum.xda-developers.com/attachment.php?attachmentid=806200&d=1323109372

----- Troubleshooting -----

For some users, the app appears not to work, while in fact it is the device itself or the cable not working. One OTG cable is not the other OTG cable. If you have a USB stick with a light on it, it should light up when you connect it to the Galaxy Nexus using your OTG cable. If it does not, either your cable or your Nexus is faulty. 99 out of 100 times it is going to be your cable. That the cable works fine with another device does not mean anything! Cables known to work on a one devices may not work on another device.

SD card unmounting: If your SD card unmounts when unmounting a USB device, you have a bug in your kernel. This is *not* a bug in StickMount !

Tests your device USB Host capability by listing the USB devices attached.

Simply run the app, plug in your USB device(s) and click find.

Copy results to clipboard ready for pasting into other software.

Not all devices have USB Host capability. For USB devices to be detected we need:

Android 3.1 or newer (USB Host API support)
Device that has USB hardware.
Compatible Kernel that links the hardware to the API. (Rooting or changing kernel can often solve USB connectivity issues, but only attempt if you know what you're doing).
USB OTG connection.
Sufficient power on the USB bus.

If USB devices are detected, details reported include:

Device Serial Number
Vendor ID
Product ID
Manufacturer String Descriptor
Product String Descriptor
Class, Subclass and Protocol
USB Version
Max Power
Number of Configurations
Number of Interfaces
Interface and Endpoint Info

Note the amount of info shown will depend on the USB device and the amount of access allowed.

This app is available EXCLUSIVELY from Play Store to protect Users from malicious app tampering.
A large number of phones/tablets provide basic USB OTG support for mouse and keyboard, but don't provide support for USB Mass Storage devices.

The purpose of this app is to determine if your phone/tablet can provide support for USB Mass Storage devices (e.g. USB Memory Stick) and specifically a connected USB Mass Storage device.

This app checks for the presence of any connected USB Mass Storage device. Screen is updated every couple of seconds, so is Conclusion when any device is connected. Special checks determine the presence of a Mobius ActionCam or #16 camera (with or without SD card inserted).

Android 3.1 introduced USB hostmode which allows the user to plug USB devices to your Android tablet in the same way as a Desktop PC and extend its functionality (if the tablet has the correct drivers of course).

This application will provide information about almost all currently plugged-in USB device (see below for more info about the 'almost').

Information includes:
•The Device class
•The USB device path
•The Vendor ID (VID) and the Product ID (PID).
•A List of all interfaces and their endpoints.

If you download the accompanying databases, the application will also be able to provide you with additional info such as the Vendor of the device (which is not necessarily the brand!), the vendor's logo and the product name.

This application uses two different methods to collect information:

1. Android mode will use the native android USB API.
2. Linux mode will parse /sys/bus/usb/devices/.

Each mode (Android/Linux) will provide slightly different information. For example Android mode will give you more information about a device's endpoints and interfaces, while Linux mode will give more information about the device itself (serial number, how it identifies itself, etc.)

Device Subclass resolution will be added in the next version.

I wrote this application as an exercise to explore fragments and the new USB host API. Hopefully it will be useful to someone else.

•The database is parsed from: http://www.linux-usb.org/usb.ids

▌ FAQ
----------
(1) What is automatic mount? Will it work for me?
The app listens for USB_DEVICE_ATTACHED and BOOT_COMPLETED intents. If your device does not send the intent, automatic mount will not work.
Also, once main app should have been opened manually beforehand for it to work.

(2) What is automatically open file manager?
After mount, the app can automatically open the file explorer..
Only some file managers (eg OI File Manager) support the intent for opening at a specified folder and are recommended.
Other file managers are just launched and are indicated with an asterix (*).

(3) Features are not unlocked / Getting repeated License check Retry?
First time verification will need internet access. The license policy is managed by google (ServerManagedPolicy), so license check may happen maximum once per session in the main app. If you find it annoying, feel free to contact me, I may change it.

Requires root access!! Does not work on KitKat and above for now.

This application allows you to enable USB Mass Storage mode on select Samsung and Sony devices.

This will export your microSD card over USB as a mass storage device, this will NOT work with your internal memory due to hardware and software limitations.

You can also create shortcuts to easily toggle between UMS on and off.

Tested or reported working on:
* Samsung Galaxy S4 (GT-I9500, GT-I9505, SGH-I337, SGH-M919)
* Samsung Galaxy SIII (GT-I9300, GT-I9305, SPH-L710)
* Samsung Galaxy Note II (GT-N7100)
* Samsung Grand Duos (GT-I9082)
Thanks to d4fseeker and Sakaschi for the methods used to enable UMS.

Internet permissions required for ads.

As of version 2.2, there's a new pro version that has auto-switching. If you have donated before, please contact me and I'll arrange a workaround for you as it's unfair for you to pay twice, thank you :)

This tool is a simple tool for Developpers.You can call Settings UI which can toggle Enabling USB Debug etc,same as Settings -> Applications -> Development.You can check your own appearance to select there.(in your environment,item numbers shown may be different from screenshots).I place this tool at my home screen.
I made this tool for practice purpose and my own use.

※This tool is not usb driver.Please install usb driver if you can't connect device and pc.Usually you can download it from device vendor's site.

ps
I got inquiry,so add notes.
At first, I try to make this tool as widget which can toggle USB Debug settings directly if you touch it.But I don't adapt it because it's not recommended way from Android 1.5. So I choose normal Activity which just finishes after calling Settings UI.
