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.

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.
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!
More info about this application at: http://forum.xda-developers.com/showthread.php?t=1468531
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:
Try the TEST version before purchasing. If the TEST version lists your devices and shows you the disk types and sizes, then it's working perfectly. The TEST version will not let you mount anything for use. You can download the test version at: http://www.interphaze.com/files/USB_Mount_All_Test.apk
Mount multiple drives and drive partions on your Honeycomb tablet. Makes all your data available.
Supports ext2, ext3, ext4, ntfs and fat32 filesystems. Can access primary and extended partitions. You can select which volumes you wish to mount, or mount all volumes with a single click.
Also allows you to mount the exernal Micro SDCard in the above mentioned formats.
STAR FEATURE: Allows you to mount the drives inside the internal sdcard directory. Allowing access to the external sdcard and usb drives to apps that normally can't access them!
Tested on Acer and Xoom. Please test your device using the TEST version mentioned above. If you don't see disk types and sizes with the test version, then this version will not work either.
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.

Share only selected files, music, folders or virtual usb , LUKS encrypted or unencrypted, disks via usb with PC/Radio car/Player ...
Also mount virtual Un/encrypted images in your device.
Usb Sharer uses UMS (Usb Mass Storage) protocol, skipping MTP/PTP.
Test Usb Sharer eval version before install it.
* Share only selected folders/directories.
* Share only desired files, preventing visibility of undesired files on your SD card.
* Share system files/directories.
To do that, select desired files/folders with your favorite application and use "Usb Sharer" to this job.
* Create virtual USB encrypted or unencrypted disks and share only files inside it, rejecting access to other files in your sdcard.
Also you will encrypt all files and data if your disk is selected as encrypted. By default encryption is AES, and uses LUKS standard.
It is possible share virtual disk as RO (read only) mode (if your device implements such function).
* Save your favorite Ubuntu, Backtrack, or preferred rescue image and boot your PC from it. Instead having one different USB flash drive for each distribution.
To do this, upload image to your device and select to share with Usb Sharer. Or save it in /sdcard/usbSharer/imgs/ directory.
* Mount disk images on your android device. Majority of kernels supports vfat/fat and ext2/ext3/ext4. But if you have custom kernel also could mount other file-systems like iso9660
In order to test if Usb Sharer works in your device you should follow next steps.
1 - Install Usb Sharer.
2 - Select some files with your favorite application, for example 4 or 5 photos from gallery, and use Usb Sharer to this job.
3 - With Usb cable connected to your PC, press share button, and check if your PC recognises the USB and only selected files are on it.
4 - Unshare this virtual image or disconnect usb cable.
5 - Open Usb Sharer application from applications menu.
6 - Create new virtual usb with desired size and share it.
7 - Check the new image is correctly recognized from your PC.
If does not work for your device please report mail opening Usb Sharer from applications menu and press menu to send mail with full info.
Please consider send mail to devwom at gmail dot com before negative rates. Keep in mind that there are a lot of devices with different configurations.
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.
You can configure the logger and read the data on the logger, as well as preview the data and save it to a file on your tablet PC or optionally send it via email.
ASCII (.txt) and .csv file formats are supported.
Finally the app does following tasks:
* read the configuration of the logger
* modify and write the configuration
* start the logger
* read log data
* preview log data in a plot
* store log data on tablet (.txt and .csv formats)
* send data via email
* manage different configurations
* examine the data in an interactive plot
* Save the plots in a graphics file (.png)
* Examine the data (in a table)
* calculate dew point and absolute humidity
* detect window-open events
Following data loggers are supported:
* Voltcraft: DL-120-TH, DL-100-T, DL-181-THP (Weather Datalogger)
* LOG32 sold by several electronic vendors
* Lascar EL-USB-1,2,3
* FreeTec NC7004 (experimental)
* maybe others (not tested)
Please test, if your datalogger works with this app by installing the free App "USB Dataloggerreader test".
Files are stored in the Download directory (therefore it needs the WRITE_EXTERNAL_MEMORY permissions).
* EL-USB-x measurement cannot be started anymore or timeout errors occur: Solution: remove the battery and insert it again. Data should not be lost.
* EL-USB-1,2 is not recognized by original WINDOWS software anymore, and the app detects the wrong logger type: the new feature "repair configuration" will cure such loggers.
Application allows you send and receive data ,monitor data exchange between serial devices, troubleshoot and test modem settings, write and save your own macros. Open as many serial ports as you like; dynamically change serial port settings without necessity to close and reopen current port; adjust baud rate, data bits, parity, stop bits, flow control parameters.
Application is fully compatible with FTDI communication interfaces based on FTDI chips FT232 and FT2232.
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.
Slick USB 2 Serial Terminal allows you to use your tablet with your Prolific or FTDI based USB to Serial adapter and connect to your serial devices.
NO ROOTING is necessary! All you need is this app and a compatible usb to serial cable (majority of cables based off the prolific or ftdi chipset).
This is the non pro version. For extended features, please look for the PRO version in the market.
Try this version first and see if it works with your setup!
This app was created in response to many sys/network admins looking to interface with routers/switches using only their tabs without having to lug their laptops around. This is only one use case. Send an email if you've found a new unique way to use this app.
