OTG cable ( micro usb B male to usb A female )
Pendrive ( usb 2.0 )
USB host diagnostics App
Farmaroot App
Es File Explorer App
Two things are important for usb otg to work in HOST mode
1. It should provide power to usb drive and
2. Kernel & Driver support
Best app for testing usb otg support for p81 is USB HOST diagnostics
The original settings on usb host diagnostics app on p81 fresh device.
Android API

Rest all other options are showing : No
<<<<<<<<<<<<<<<<<<<< SOLUTION >>>>>>>>>>>>>>>>>>>
STEP 1 : ROOTING
I have rooted my device using FARMAROOT app Version 1.9.3 ( single touch method ).
This app doesn’t removes your previously stored device and app data so this method is very safe for rooting.
Usage
Install & Open Framaroot and select the following action :*Install SuperSU
Done !
STEP 2 : ANDROID API
1. CREATE File : android.hardware.usb.host.xml
Goto folder /system /etc/permissions
To enable USB host API support you should add a file named*( android.hardware.usb.host.xml ) and containing the following lines:
<? xml version="1.0" encoding="utf-8"?>
<permissions>
<feature name="android.hardware.usb.host"/>
</permissions>
Copy this file into folder*/system/etc/permissions
2. MODIFY File : handheld_core_hardware.xml
Goto folder /system /etc/permissions
find filename *handheld_core_hardware.xml
and add*<feature name="android.hardware.usb.host"/>*into**<permissions>*section
3. COPY the above two Files in this location : /system /etc /permissions
4. Reboot your device.
After adding two xml files.
This are the current settings on usb otg diagnostics.

Hi, thank you for using XDA Assist. Unfortunately this is not the proper place to post this as very few users will see it. There also is not a specific forum for your device so I'm going to ask a moderator to move it here, http://forum.xda-developers.com/general/general

Rooting Funbook Infinity P275
Rooting & Unrooting Funbook Infinity P275
Android rooting is the process of allowing users of smartphones, tablets and other devices running android to attain privileged control (known as "root access") within Android's subsystem.
There are two methods for rooting our Funbook Infinity :
1) Root Many Android! by Bin4ry
2) Super One Click by CLShortFuse
Both are very easy methods, but I prefer using Universal Rooting Script by Bin4ry. However, I will post how to root in both methods!
Preparing Funbook Infinity For Rooting :
1) On your infinity tablet, go to Settings- -> Developers options and tap on USB debugging to check (tick) the USB debugging on.
2) Connect the Funbook Infinity with your Windows Computer via USB cable.
3) If it is the first time that you have connected your tablet to your computer, then allow windows to Automatically Install the Drivers for you.
4) Change the Connectivity Option from MTP to Mass Storage in Settings --> Storage --> Options --> USB computer connection
If the drivers are not installed automatically then you nedd to install them manually. Go to 3rd post for the guide on installing ADB drivers manually.
Note : Remove your SD Card from your Tab.
METHOD 1 :
Root Many Android! BY BIN4RY
1) Download Root_With_Restore_by_Bin4ry_v31 : HERE or HERE [OP LINK]
2) Extract & Double-Click RunMe.bat
3) Follow the instructions
4) Connect your tablet to the computer.
5) Then, the program will ask you to go to the tablet and
tap Restore My Data. Do it.
6) Wait till it finishes. Your tablet will restart once.
7) Once the program is done, press Enter.
8) Your Funbook Infinity will be rooted.
METHOD 2 :
Super One Click by CLShortFuse
Note : The program requires Microsoft .NET Framework 2.0+ or Mono v1.2.6+
1) Download SuperOneClick Root v2.3 : HERE [ORI LINK]
2) Open SuperOneClick.exe
3) Click the Root button and wait for a few minutes.
4) You can select Yes, if you would like to test it.
5) Your Funbook Infinity will be rooted.
Unroot Your Funbook Infinity:
i) Use Root_with_Restore_v31
Select the Unroot Option from the list.
ii) Use SuperOneClick
Click on Unroot on the SuperOneClick.exe window.
z
CWM Recovery 6 For Funbook Infinity P275
ClockWorkMod Recovery
Screenshots in updated CWM recovery:
Prerequisite :
Your Funbook Infinity Must Be Rooted In Order To Install CWM.
Credits to dolorespark for posting this.
1) Downlad CWM_6028_P275.zipfrom HERE [Dev-Host]
and Novo_Tools.apk from HERE
2) Put both Novo_Tools_1_0.apk and recovery.img in /sdcard of your Funbook Infinity.
3) Install Novo_Tools_1_0.apk as a normal app.
4) Open NovoTools and grant SU (SuperUser) permissions.
5) Click Flash Recovery in NovoTools and wait for few seconds.
6) Next Click Enter Recovery in NovoTools and You will go to CWM Recovery 6.0.2.8.
Note :
i) If You Want to Go To Recovery :
ii) Switch Off the Tab.
iii) Press and Hold Home And Power Keys at the same time.
or
Use Novo_Tools.(Enter Reocvery option)
Note : This updated CWM reocvery contains the *** Go Back *** option which favours devices like P275 which doesn't sport back or volume rocker button.
Installing P275 ADB Drivers :​
If your tab is not rooted, even after trying both Methods, then the problem must be the ADB drivers. Here is a guide for installing them.
1) First, download the P275-Drivers.rar from HERE [Dev-Host] and Extract it anywhere in your PC.
2) Go to Settings > Developer Options > (and tick) USB Debugging ON
3) Connect your tablet to your PC via USB Cable.
4) Open Device Manager (Seach in Start)
5) Under Other Devices, you will see Android with a caution symbol.
Note : If you do not see the Android with a caution symbol, then ADB drivers are already installed in your PC and you don't need to continue...
6) Right-Click on Android and select Update Drivers and a dialog box will appear. Select Browse my Computer for Driver Software
7) Browse for the folder that you extracted earlier and click OK.
8) A warning will appear. Click Install the driver software anyway.The ADB drivers will be installed.
9) The caution symbol will disappear and you will see Android Composite ADB Interface.

But I want to know how to go back to stock recovery after installing CMW?
The only reason I think I will go back to stock is in situation where in I have to take the tab to the service centre.

[GUIDE] How to work with MTK Engineer tools - Monitor radio - Modify NVRAM &more

Hello!
In this thread I want to show you how to use MTK Engineer tools. You will need a phone with a MTK (Mediatek) chip to work with this tools.
The most important tool I want to introduce you is MTK Catcher. MTK Catcher is an engineer program for Windows which allows to log and debug low level information on MTK devices (running android). The most interesting thing is that you can see GSM/UMTS radio messages between the phone and the cellular network. This is something special because all mobile phones have proprietary baseband firmware. We can gain insight in underlying GSM/GPRS protocols. MTK Catcher will display the information like in Wireshark. Xgoldmon and OsmocomBB are other projects which give the possibility to monitor this information but this is by far the user-friendliest way to do this.
However there is more potential behind this. The problem is that everything is proprietary here. It would be great if we could parse all information direct on the phone with MTK Catcher. We need to reverse engineer how MTK Catcher decodes the information using the database files. If we can analyze low level data direct on the phone, we could use e.g. this information for our IMSI Catcher Detector project to detect IMSI Catchers aka Stingrays much more reliable (Here you can see what kind of information we need to achieve this).
For more information about MTK Catcher read the manuals.
Warning: Working with Engineer tools means that you can damage your phone! Everything you do is at your own risk!
a) Capture network events and analyze later
Check if you have MTKLogger installed, this tool comes preinstalled on many MTK devices
Open MTK EngineerMode (you can use Mobileuncle MTK Tools to do this)
Open MTKLogger in “Log and Debugging”
Activate option “ModemLog”.
Start recording with MTKLogger and stop later.
On your sdcard you will find folder “mtklog” where all captures are saved including a database file.
Copy mtklog from your phone to PC
Open Catcher.exe
Select in Config → Database path your database file (BPLGU...)
Select in Controls → Dump File your MDLog_PS file (MDLog_L1 is not displayed)
b) Capture network events live over USB and access phone with other tools
You will need the database file so obtain it doing the procedure under a)
Activate USB Debugging in Developer Options
Open MTKLogger preferences
In ModemLog menu change Log Mode to “USB Mode”
Install MTK USB drivers
Install ADB drivers
Connect your phone with USB cable to your PC
Open Catcher.exe
Select in Config → Database path your database file (BPLGU...)
Start recording with MTKLogger *important*
Select in Configure Port → Conn. Mode “Smartphone USB Logging (MD1)”
Select in Controls → Set Filter what you want to display or just select all
Check Advanced menu out, there will be e.g. SIM/USIM Editor
How to edit NVRAM
Install MTK USB drivers
Install Maui META
Power off your phone
Attach your phone to USB → VCOM port should get installed
Open META (it needs admin privileges to create log files under C:/)
Select in Options → Connect Smartphone into META mode
Press Reconnect button
Attach powered off phone to USB
Power on the phone → Phone should get stuck on boot screen and fail driver install
Open device manager, Select “ALL MTK Drivers” as driver update path
Gadget CDC VCOM appears
Detach phone from USB
Power off the phone (hold power key for 10 seconds or remove battery)
Close META and try again the steps 5-9
If not successful try again 5-9 and 12-13
META shows “Connected with target” → Phone is in META mode
Select NVRAM editor in drop down menu
Press “Read from NVRAM” button
Select database file (BPLGU...)
NVRAM Records that might be relevant for logging:
NVRAM_EF_PORT_SETTING_LID:
usb_logging_mode: 1
tst_output_mode: 1 (to file)
NVRAM_EF_TST_CONFIG_LID:
usb_dma_logging_enable: TRUE
Please share everything relevant about what you could find out regarding MTK engineer tools! Thank you!

Thanks, excellent post! I was trying to analyze what is wrong with a MT6752 device and also to correct some NVRAM errors in a MT6592 device (lost wifi MAC address). Catcher seems like the perfect tool for that. Wish I had seen your post long time ago.
is there any solution to see realtime the codec in use for a call?

The last rom i installed have root privileges the i created the file android.hardware.usb.host.xml in /system/etc/privilege that was missing.
But issue is not fixed. Please could you help me?
The reason i need to use USB AUDIO PLAYER PRO is the only app to have hi-res audio streaming. Can bypass Android 16 Bit 44.1 KHz limit and go up to 24 bit 192 KHz.
Thank you.
How USB / USB-OTG is implemented is hardware specific, the related drivers are NOT part of Android OS itself, they are provided by OEM.

so fot you the only way to have it is to restore stock rom from Huawei?
USB OTG CHECKER app you ran told you the USB-hardware build into phone doesn't support USB-OTG. So what should be the reason to re-flash phone's stock ROM?
