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!

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.
- 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:
The discussion thread on XDA-Developers can be found here:
This application will provide information about almost all currently plugged-in USB device (see below for more info about the 'almost').
•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.

This app will install custom kernel to your Nexus 7, that will add HID keyboard/mouse gadget functions to it's USB port.
No driver installation is needed for your PC.
It will work inside BIOS, inside bootloader, with any OS, and with any hardware - PC, Mac, Xbox, Chromebook, even with other Android devices through USB Host adapter.
Only Nexus 7 2012 WiFi with Android 4.4.2 is supported at the moment.
If your Nexus 7 is not rooted - follow installation instructions at:
If you have any other device, you may try to compile the kernel yourself, using kernel patch from this webpage.
Works best with Hacker's Keyboard: https://play.google.com/store/apps/details?id=org.pocketworkstation.pckeyboard
I'm planning to add remote control functionality, with live camera feed,
so you can turn your Nexus 7 into an overpriced remote desktop / KVM switch solution.
Frustrated by the lack of mass usb storage mounting in your android device? Well look no further. Now you can. You'll now recieve standard android notifications when you connect your device via usb. Mount and unmount with ease.
And as an added feature now you can automatically mount your sd card. Just plug your device in and up comes the file window on your computer. (this feature can come in handy for any rooted device)
---- ATTENTION ----
This will only work on rooted devices and requires a kernel that has the ums enabled. For Xoom users this means a kernel like Tiamat <= 1.40) For other rooted devices enjoy automount.
Starting from Android 3.1, applications can use functions of USB host, but many devices have this functionality disabled.
This application checks whether USB Host support is enabled. On rooted devices, an attempt to enable USB support can be performed.
Applies to a feature with the Android 3.1 or later, and USB Host function. You may need to use a special cable features USB Host.
Bugs you have any interest http://twitter.com/SyncHack request. Thanks.
Not all devices are supported, therefore it is strongly recommended that you try the 'Sixaxis Compatibility Checker' (available for free in the Android Market) before purchasing this app.
Finally the wait is over... The ultimate gaming experience awaits! Now you can play games on your phone the way they were meant to be played! Sixaxis Controller allows you to use your PS3 Sixaxis, DualShock 3 and Navigation controllers in many of your favourite games and applications.
*** IMPORTANT ***
- ROOT access is required!!!
- Due to the way pairing is done with the controllers, you need to manually pair your controller with the PC utility 'SixaxisPairTool' (available on the website) and a mini-USB cable. Android 3.1+ users can also pair directly on their devices via USB.
- It is highly recommended that you use an ORIGINAL controller. Many after market controllers will not work with this app. If you get a 'Client connected: 1' message, but the lights on your controller continue to flash, it is almost certainly not an original Sony controller.
- The fake controllers that are most likely to work (though not guaranteed) are those made by Gasia. If you bought a fake that works but isn't made by Gasia, I'd love to hear from you so I can compile a list of known working controllers.
- Be sure to read the instructions in the help menu carefully.
- Up to four Sixaxis, DualShock 3 and Navigation controllers supported at once.
- Support as a native gamepad in Android 3.1+ devices. Full support for analog sticks and analog triggers.
- Keyboard emulation. Map all buttons and sticks to almost any key available in Android.
- Mouse emulation. Configure a button to activate the mouse pointer on devices that support mice (most tablets, and many phones should work).
- Touch emulation allows you to map buttons and analog sticks to the screen. Play all your favourite games with full analog support, even those without built-in controller support!

Q: Why my phone/tablet(Android 3.1 or upper) is incompatible?
A: Maybe, your phone/tablet does not have a USB Host API feature.
Q: But my phone/tablet supports a USB thumb drive, USB mouse and USB keyboard.
A: It's not a USB Host API. It's a Linux USB Host. Please check to see if your phone/tablet have a USB Host API.
Q: Can I get binary or source code?
A: Yes, It's open source. Please check my github page.
Q: How much max output current is?
A: smartphone type : 150 - 180mA(Galaxy Nexus, Galaxy S2)
tablet type : 400mA - 500mA? (ICONIA A500, Nexus 7)

Q: Why my smart phone detect usb device?
A: Smartphones make sure it supports the USB Host.
In addition, the Android version 3.1 (API Level 12) from the USB Host support.
Occasionally on the smartphone does not recognize USB devices (eg Galaxy Note 1). Smartphone otg cable to connect to leave only the part that is connected to the equipment by unplugging and re-connect if you recognize that this case is.
This can support for the FTDI USB-Serial Cable.
1. insert the USB Host cable into phone ubs connector.
2. connect FTDI USB-Serial cable with USB Host cable.
3. install and run this Serial Terminal App(this App)
This is Pro Version.
It can support the 1200, 2400, 9600, 14400,19200,115200bps.
