When you plug a USB thumbdrive to the phone, it first recognises the drive name but doesn't show any options to use it (even in file manager).
Maybe it's due to the connection type (MTP only)...
Any ideas?
Can you access your files in your USB thumbdrive using the file manager?
I'm using Astro Manager to access, and play my video files directly from the USB thumbdrive.
In fact, I just realised I can access if I keep pushing the cable to the phone... Maybe the cable connection isn't that good. I'll buy a new one.
New mission will be to enable wake using volume key which might be more difficult...
Thank you for your answer!
On my tablet , I use USB host ( full usb connection ) , which means I can plug in a pen drive , keyboard , mouse etc...
Can I do this on the Xperia S ???
With a micro usb adaptor I assume ??
Just found a Vid : The answer to my question is yes !

This will enable you to use USB on the go (OTG) feature that comes with Android 3.1 on our Jetstream. However, I for one don't think its truly on the go because you do need an external power source for it to work. But it allows me to connect my hard disk and work with it without the intervention of a computer which is more than great for me. But would surely like it if you could directly plug in a pen drive (not yet possible I think as far as I could search).
I have note made any of these, have just researched, tried a lot and managed to get it to work on my Jetstream and am just compiling the steps and methods I followed here.
Thanks to sztupy for his thread http://forum.xda-developers.com/showthread.php?t=1450298 for giving the basic idea.
Thanks to hellcat82 for his software NTFS Mount found at http://forum.xda-developers.com/showpost.php?p=13337600
Pre-requisites:
1. Must be rooted with Superuser and Busybox loaded
2. NTFS Mount software (use version 1.2 as 1.3 has some issues with Busybox as per the above mentioned thread and personal experience) - alternate is USB Mount by the same developer available on the Play store at https://play.google.com/store/apps/details?id=au.dach.drivemount (however I have not had success with it)
Hardware Requirements:
1. USB OTG Cable. Can be found at http://www.ebay.com/itm/Micro-USB-H...370670?pt=PDA_Accessories&hash=item3a731ccdae
Just a sample, costs around $ 2. I got mine from a local hardware store for Rs. 300 ($6)
2. USB Y cable. Can be found at http://www.ebay.com/itm/USB-2-0-Min...552?pt=LH_DefaultDomain_0&hash=item1e624b8dd0
Just a sample, costs around $ 2. I had one lying around at home.
3. USB Charger. Can be found at http://www.ebay.com/itm/Black-Plug-...er_MP3_Player_Accessories&hash=item1c254df23a
Just a sample, cousts again around $ 2. I got mine from a local hardware store for Rs. 170 ($3)
4. USB Hub (OPTIONAL) - this will enable you to connect more than 1 device at a time. If plan on using this, then you can get one with an external power source and skip the USB Charger.
Procedure:
1. 1st, after obtaining root, confirm that USB Host more is enabled on the Jetstream by checking the build.prop under /system using Root Explorer found towards the end of the screen. It should read as:
# support USB Host
rp.usb_host = 1
If not, then you must enable it by allowing R/W mode.
2. Next step would be to set up the hardware in the right manner. Note this must be done before connecting anything to the tablet.
The USB Y cable comes with 2 male USB ports and a single female USB port. The USB device to be connected must be attached to female port. The USB power charger must be attached to the side Male port and the USB OTG (micro USB to USB female) goes to the main Male port. With this all necessary connections are made. Refer to the attached picture (thanks to sztupy again) for details on other ways of connecting and using including with USB Hub (I personally have not tried the hub).
3. Put on the power source that is connected to the entire system and in case the external hard disk also uses one, that needs to be put on as well.
4. Lastly, connect the Micro USB cable with all the above connected to it to the tablet.
5. In order for the device to read/write or access the USB storage, next step depends on if the device is FAT32/NTFS
a) for FAT32 - you can go to the settings, storage and scroll down to USB storage. You will be able to see the details of the connected hardware and can click on Mount to mount and use. Unmount later to disconnet.
b) for NTFS - you must open NTFS Mount software. From the drop down list of devices, select a device (mine always shows sda1) and click on mount. Unmount from here itself later when done.
By following this, you would be able to access your USB external storage (pen drive/hard disk) with ease from your tablet directly.
Note: in order to access the files, you must use Root Explorer/Astro File Manager.
FAT32 device appear under USB folder of sdcard (i.e inbuilt memory)
NTFS devices appear under /mnt/sda1

2. NTFSMount1_2.apk - NTFS Mount (thanks to hellcat82)
Hope this helps.
Is it truly necessary to have the OTG usb cable? I currently have a powered hub. Shouldn't I be able to use the provided JetStream usb cable and tie the devices together through the hub?

Hi, sorry for delay, was out for an exam.
I don't know if or not it will work. As I said I have just researched and seen what others have implemented and put it together.
Perhaps you could try and let us all know because I don't have a USB Hub (powered or otherwise) and hence have not tried it out.
This all seems a little much for OTG support considering it was just plug and play with my SGS2 and also my SGS4G. I am hoping to see some more development in this area as this type of support is nice to have on a tablet of this caliber.

Hello,
I've used my tablet with flash drives etc. with the OTG cable. Before few days the OTG stopped working.
I though it's from ES File Manager because I use this app very often and I have clicked somewhere and disabled the OTG function.
So, I made decision to pre-install my android firmware and clear everything. > I did this.
And then I put the OTG cable with the flash drive connected and then a USB mouse - the flash drive does not connect, the optic ot the mouse only lights up and then it goes off and the mouse does not work too. I tried the OTG cable on my phone (SGS 2) and it's working perfectly.
Can you guys help me to solve this problem?
Hi,
i recently gotten hold of an allwinner A31 device being the measy B4K. (http://www.measy.com.cn/product/showproduct75_en.htm)
I also gotten hold of a firmware update for this device from a guy that was in contact with measy support using a chinese friend:
http://www.freaktab.com/showthread....S918S-firmware&p=130534&viewfull=1#post130534
firmware rom download is here : https://alimail.alibaba.com/alimail...eb961&[email protected]
Now from what i've seen from other a31 devices is that you have to use the phoenixlivesuite to upload the firmware and you need usb debugging for this (the tool itselve says so also). but the device only has 2 female usb ports and no usb micro port not even on the PCB that i can see when i opend the box. One of the guys bought a normal male to male usb cable and tried in the diffrent usb slots but was not able to get any response. some others said that you need an usb otg cable but does that even exist for a usb male to male cable ? (if so where) if not would using a micro sd cable from my phone with a usb micro female to usb male adapter do the trick ?
also the img file is in some special format but it can be unpacked well almost all files using the tool from this thread http://forum.xda-developers.com/showthread.php?t=1753473 and it gives me all kind of *.fex files like uboot.fex, recovery.fex etc it only had problems with one fex file being sys_partition.fex but i did get a system.fex of 400mb.
i have root on the device also and i can get into recovery mode using a reboot to recovery apk however it's useless since i can't move around in it, the remote don't work, nor a keyboard attached to it and it has no physical buttons.
Anyway my main question is what sort of cable should i get to get this work a usb male to usb male or just some usb female to usb male adapter + usb micro phone cable to get usb debugging working so i can at least get windows to recognize the device.
I'm also posting this for other people since i don't think many people know about that firmware file for b4k, perhaps others having the same device have more luck
thanks
Hi everyone,
I often transfer files between my Samsung S7 Edge and my Windows PC through USB cable. However, after (making the mistake of) letting it upgrade to Oreo (v8.0), this is no longer possible: connecting the phone via USB to my laptop only shows charging information in the swipe-down top menu, and I no longer get the prompt asking whether I want to allow access to the phone's contents. Consequently, the phone's internal&SD memory no longer shows up under Windows Explorer.
I've been searching for a fix/workaround for hours (thanks Google for this quality time!). Some of the things I've tried that didn't work:
- enable/disable USB debugging mode under developer options
- change "USB configuration" (under Developer Options) to "MTP" and to all other options there
- use a different USB cable and USB port on the laptop
- search for apps on the Play Store that can help with this (didn't find any that actually do the job)
Connecting Android phones to Windows laptops to access their internal memory through USB cable has (bemusingly!) been a problem with this ****ty OS as long as I can remember, so it doesn't surprise me that users are having to spend even more time now to get it to work again.
Any suggestions much appreciated!

Thanks - I tried that, but I still don't see the phone's memory as a USB drive, nor any permission prompt on the phone once I connect it.

Try to reinstall drivers ,uninstall all previously installed use USBDEVIEW tool .
https://www.nirsoft.net/utils/usb_devices_view.html
Before I do that, I should note that, when I tried on a different Win 10 PC, I get the USB drive back no problem, so the problem is Windows/PC-related, it seems?!
Turns out that, when using another USB cable, the phone is once again seen as a USB drive. I didn't think the cable could make a difference! Hope it helps others
