I am using Neo V official build 4.1.B.0.431 (ICS 4.0.4), rooted, unlocked bootloader (doesn't seem to matter)
I've downloaded the kernel source code, compiled the `usb-storage.ko` module, and placed it on `/system/lib/modules/drivers/usb/storage/`.
I've also changed `/system/etc/vold.fstab`, added this line:
Code:
dev_mount usb /mnt/usbstor auto /devices/platform/msm_hsusb_host.0
Then I restarted the phone.
After that, I typed the commands (using root) in shell:
Code:
mount -o remount,rw /
insmod /system/lib/modules/drivers/usb/storage/usb-storage.ko
cd /mnt
mkdir usbstor
Then I plugged in the OTG cable with a USB Flash Drive.
The storage is successfully mounted (by vold, I think), as I can verify in Root Explorer. I don't have photos so can't verify whether media scanner can detect it.
But in Settings->Storage it didn't appear. Seems that the Settings app don't support. I cannot unmount it using GUI, so when I remove the storage it warns me about that.
Are there any ways to get the Settings app to show my USB storage so that I can unmount via GUI?
Also how to automatically `insmod` and create `/mnt/usbstor` when startup? I won't bother editing ramdisk, but anything under `/system` is fine. I saw a few shell scripts under `/system`, are they fine to use?
Download USB otg from market. It's for both, arc s & neo/ neo v.
Use it with caution it may burn your motherboard....

Fine. I didn't use any piece of compiled binary anywhere else, but I've done the following:
1. insmod and create mountpoint using `/system/etc/pre_hw_config.sh`
2. edited `res/xml/storage_list.xml` in `framework-res.apk`.
Now the USB storage shows up in system storage settings. The name showed "USB storage" though it still shows "mount USB". I can normally use it now.
It seems to be better than using 3rd-party applications.

Hi Alvin,
I´m having big issues with enabling USB Host mode as well (phone does not find any usb devices such as usb mouse or a pendrive), so I would greatly appreciate your help in finding the root of this problem. Here are the details and what I tried so far:
1. Im running on a rooted GT-i8530, leaked 4.1.2 rom with busybox installed
2. android.hardware.usb.host.xml permissions xml file exists in etc/permissions and just mentiones the apache license
3. Running USB host diagnostics I got:
Android API
Claims support yes
classes found yes
device detected no
Rooted API
Claims support N/A
Device detected N/A
Kernel
Claims support Yes
Device detected No
Verdict OS support No
3rd party apps No
4. I tried 3 different USB cables (original samsung one with female to female connector), another original micro usb to female plug, and a no name one,
5. No mouse nor usb sticks (fat32) seem to be recognized (below 200 ma)
6. Had a look into the storage folder and I can see a folder for external sd, sdcard and UsbA-UsbF. These Usb folders have no permissions set ( like rwx). Looking into the mnt folder I can see the same but in there the Usb folders have rwx permissions set.
7. I was thinking to manually mount the pendrive but when type into terminal as su: ls /dev/block there are no devices (like sda, sdb, sdc) or partitions ( sda1...) mentioned. So I didnt even try commands such as mount -t vfat /dev/block/sda1 /mnt/sdcard/usb...Only mmccblk, loop, dm, ram, vold, param is mentioned on dev/block
8. In vold.fstab all usb(a-f) folders including paths are visible
Now I read your post regarding the usb-storage.ko module and I guess thats whats missing for the phone in order to recognize any usb devices. Reason why I think that is because once I connect a usb device I cant even see any sda´s or sda1´s...In system/lib/modules the folder driver is non existent but I found in sys/module/usb_storage/drivers a usb-storage file but its not a .ko What do you think? I would appreciate your thoughts on that one..

Ok first things first : If you installed some launcher and your touch screen is not responding and you dont have USB debugging enabled then the only way to fix that is to install the original firmware, dload from here : http://www.androidtablets.net/forum...huawei-ideos-s7-slim-official-firmware-4.html check post 35 for the one i used
If you do have debugging enabled the download Superoneclick from below.
The super one click can aslo root the S7 slim and it has adb installed. Unxip it somewhere and go into the \adb folder. Open command prompt from there and run
Adb devices
If it doesnt show your device the either the debugging is not enabled or the right driver is not loaded. (Menu, Settings, Applications, Development, USB Debugging (Yes))
type adb shell
cd\data\app
rm *launcher*.apk
exit
adb reboot
This will remove the launchers thats faulty and touch screen will work again.
If you guys find a clockworkmod that works then leme know here cause i loaded the wrong one and its messed up.

this works great - - i had a problem where i have not been able to recover my internal SD card - tried everything - even back to original eclair and all - now i just use the external sd (16gb) for everything. No problems with camera recognizing sd card or programs not downloading, etc, etc....
I'll still try to maybe swap out the internal card, or try to get it functional again somehow, but in the meantime, the S7 if again functional.
Rom
Im currently using this rom an dit works perfectly : http://www.androidtablets.net/forum...ical/15812-rom-tri_zet-ideos_s7-slim-mod.html
Only problem i had was updating google maps so i just loaded the new version via .apk manually
O yes If you load that rom and it comes on the first time the screen might not respond (stuck on lockscreen) but its busy loading software in the background. Mine came up on the lock screen saying connect charger although the battery wasnt low so i plugged the charge cable in. It then rebooted after a while and the touch screen is working perfectly.

I just got my Slim S7 yesterday, hated the launcher so I replaced it not thinking it would cause such a problem... long story short I tried installing the rom you linked hoping it would fix it(tried everything else) and the touch screen still is unresponsive and USB debugging is now disabled. Any ideas?

well I finally got it working. I ended up doing multiple battery pulls and installed the geeksu recovery, and that's all I did. I'm up and running on that rom. Only thing is thatbi somehow lost root, but that was no biggy.
A one-stop no-pain solution for enabling and using USB OTG mass storage on your android phone!
What is USB OTG?
It stands for USB On-the-Go!
"It is a specification that allows USB devices such as digital audio players or mobile phones to act as a host allowing a USB flash drive, mouse, or keyboard to be attached." - Wikipedia
The stock kernel allows Mouse & Keyboard, but USB storage is missing..
Features:
Stock and custom kernels supported
Mount and Unmount drive with a single click
No Ads!
Full NTFS support built-in!! (from v3.0.3)
Automatically start on device connect (intent broadcast) (from v3.0.3)
Notification when drives mounted! (from v3.0.3)
One click access to unmount (from v3.0.3)
Option to enable UTF-8 if kernel support (from v4)
Automatically open explorer after drive mounted (from v3.0.7)
One click debugging and feedback (in app)
What phones are supported?
Sony Ericsson Xperia Neo, Neo V, Ray, Arc and the Arc S! Modules for stock kernel on second post.
If you get it to work on other devices, please PM me and I will add them to the list.
Please note that this app is an "Helper" app.. it will not magically make your kernel support USB Mass storage
What are the requirements?
root (su binary)
busybox
USB OTG cable
How to use on stock kernel?
See this post to load modules!
WARNING
I will not be held responsible for any damage to your device. Do not use for a long time, u may risk burning the device chip/motherboard due to the voltage supply in host mode.

Yes, just try "MOUNT" first.. Only if it fails, try "Setup".
What exactly means: "Do not use for long time"? For how long can I use mouse or keyboard? Or xbox 360 wireless reciever? Or maybe it applies only to usb storages?
Is it like 15 mins or more like 2h?

Try after mounting your phone's /system as R/W.
okay now I've updated and reinstalled busybox and superuser and tried again. Now it says "storage modules live" I then connected a pen drive to my usb otg cable and attached to the phone, then mounted it. It says "mounted on sd card". Now when I browse with a file manager I can find an "usb drive 1" directory but nothing is in it!
The drive most probably is NTFS formatted.. Use script manager file browser to view files
still no luck!
Not all flash drives work. Mostly low-powered and low capacity ones only work. Try connecting to a powered hub, it should work, including external hard disk drives. (This is for the guy above me)
My other device, a cheap generic chinese tablet works with every flash drive I throw at it, 500Gb portable hard drive even. And it is connected directly, not via a powered hub. And any file system (NTFS, Fat, Fat32); ext and hfs/+ not tried.
Regarding how long is safe using usb otg, I have been watching movies from full battery down to empty usually 2 full-length movies and have no problems with it using xperia arc. Maybe that's the reason it won't charge and host at the same time. To protect the hardware. Once the phone is out of juice, you'll be forced to stop.
Hope that answers the perennial question of "How long is safe?" I have seen at almost all usb otg/host threads.

I have the exact same problem.
I've tried two USB-flash drives, one is a Kingston DataTraveler G2 16gb (NTFS), the other is a Kingston DataTraveler G3 4gb (FAT32), the only thing I have on the drives are 2 .apks.
By the way, I'm using a NEO with the Neo V's official ICS from Sony.
When I mount them, the LED in the drives flashes a few times, but that doesn't happen when I go in to the "USB drive 1" directory (wich is empty).

Hi, I have a MB860 rooted and running Cyanogenmod. A few days ago the touch and LCD died. (presumably by break Flex).
I want to recover my data and pictures of internal storage, but the phone has PIN lock screen and only USB Charge for default (I can't change to Storage mode). When I connected to the PC I can access to RSD mode.
How I can recover my data with broken screen?
Thank you and have a nice 2014.
Greetings from Chile.
In the development section, there's a thread that discusses dual boot. Use that basis to copy the internal storage to an sd card or to your computer. There's not much you can do without the screen :/
Sent from my MB886 using xda app-developers app
Via ADB, you can copy contents from internal SD to external. Cp /sdcard/DCIM /sdcard-ext/bk_camera for example (the paths won't fit, I don't remeber the right ones for cm7)
Hit the damn thanks button instead!

You didn't say which CM version you're using. There are at least 4 generations available for the Atrix.
You can try this via command line. Make sure you type it out exactly as specified. You type in only the bold stuff, the rest are prompts/comments.
Code:
[color=grey]>[/color] [b]adb shell[/b]
[color=grey]$[/color] [b]su[/b]
[color=grey][i]#-- internal SD[/i][/color]
[color=grey]#[/color] [b]echo /dev/block/mmcblk0p18 > /sys/devices/platform/usb_mass_storage/lun0/file[/b]
[color=grey][i]#-- external SD[/i][/color]
[color=grey]#[/color] [b]echo /dev/block/mmcblk1p1 > /sys/devices/platform/usb_mass_storage/lun1/file[/b]
That should make your SD card(s) visible as windows drives.
When you're done, do "safe remove" in windows and then this:
Code:
[color=grey]>[/color] [b]adb shell[/b]
[color=grey]$[/color] [b]su[/b]
[color=grey]#[/color] [b]echo > /sys/devices/platform/usb_mass_storage/lun0/file[/b]
[color=grey]#[/color] [b]echo > /sys/devices/platform/usb_mass_storage/lun1/file[/b]
This should work at least on CM7 (kernel 2.6).
@andresrivas @ravilov that was what i was getting at, i just didn't remember the exact command lines to input to get it done, thats why i pointed in the right direction.

An alternative would be to USB mount from CWM, presuming you are using CWM. I'm not sure how it goes if its in TWRP or other recoveries. I've done it in that fashion ever since my digitizer messed up. Still looking for a way to fix it. No parts sold where I live
The adb trick should run fine.
If you have original firmware(or some of the very alpha cm9/cm19 kernels w/ HDMI enabled) you can try connecting the hdmi to a tv and see if you have the mirror feature enabled. If so, you can see your screen. As for input, you would need a usb keyboard and the multimedia dock or a hack cable.
I was experiencing the wifi+bluetooth ship failure that I fixed once, twice, ..., but the fix didn't last
My last attemp to fix that resulted in a flex cable ribbon damage (bad move)
Power button and touch screen are now broken
Sounds like it's time to change phone :crying: I'm not willing to repair this time
I'm trying to access internal storage but I am stuck:
I can:
- access bootloader options (buy plug-in power or usb cable)
- go into recovery, but I can't validate my selection (no power button)
- go into fastboot, but it seems that mounting is not a fastboot possibility
- go into rom (fastboot reboot), but I need to touch screen to activate usb mount
Any idea ?

Do you have a custom recovery? If so, you should be able to access the shell through adb and USB while in recovery.

If ravilov method works, write an android program that registers for onBootReceiver. In onReceive() have this code
Settings.Secure.putInt(context.getContentResolver(), Settings.Secure.ADB_ENABLED, 1)
Put the apk under /system/app and change the permission to rw-r-r
Restart your phone, the above app must run onBoot and u will have usb debugging enabled.
Lets see how things go.

Looks like u cannot mount sdcard. I found something about adb enabling in init.rc that u can retrieve. Put your phone in recovery and connect to the system and do adb shell
You must be in # prompt. Pull out init.rc using the command "adb pull /init.rc ."
I am attaching my init.rc. diff it and you should find differences wrt to adb. Try replacing the adb differences and ensure the chmod is done for init.rc (initial permissions)

adb device is ok
I got the init.rc with adb pull, it is exactly the same as yours
I tried adb pull emmc
pull sdcard
pull scard0
pull scard1
pull storage
etc
Some don't work, some work but I got only files from "sys" folder
I tried this
http://forum.xda-developers.com/showthread.php?t=2339530
Same folder issue
I tried adb shell su mount but I don't know what to do with it ^^
Since our init.rc are similar, I also tried [email protected] but I have nothing in the device list (while phone is on)
If you enabled root for adb inside the rom, you can use the following command in adb to mount the internal storage:
echo /dev/block/vold/179:97 > /sys/devices/virtual/android_usb/android0/f_mass_storage/lun0/file
That will mount internal storage as usb storage and you will be able to access the files from a computer.
Edit: I just read that you don't have it enabled >.< Another way would be to use "input tap x y" which does not require root but as you don't have it enable, something has to be done through recovery.
Second edit: Try this inside recovery:
adb shell
mkdir sdcard0
mount /dev/block/mmcblk0p18 sdcard0
Now that the internal storage is mounted on sdcard0, exit adb shell and use the following command:
adb pull /sdcard0 sdcard
This should copy all the files from the internal storage to a new folder called sdcard in your computer.

Thanks all for help
Problem solved
So i thought my usb port was damaged, replaced it, still no data connection. charging just fine. all usb settings are greyed out.
I thought it may have been rom related, flashed a new rom, it replaced my recovery as well unfortunately, on first boot it installed an OTA to the 2nd slot, which also replaced my recovery, I cannot access ADB except over wifi which is pretty helpful but cant sideload over wifi, cannot access fastboot to flash any of the good stuff. I can use root but only through adb shell on computer which is a godsend.
I managed to manually install busybox, so i have that. cant figure out how to flash firmware without usb access. cant figure out how to pull patch and push my boot image with magisk without fastboot.
checked my init script as well as the init.usb scripts and compared them with a generic one online, they seem ok as far as i can tell. getprop shows usb is ok. But:
