Xperia ARC S USB OTG possibilities

ARC S (LT18i) comes with USB OTG support but when I plug an USB memory stick it recognizes it but says it's not supported.
From what I read it only works with LiveDock which is, by my opinion, not good at all, not even a real dock since you have to plug a cable in phone.
so is there a simple possibility to make USB work without LiveDock?
by simple I meen without flashing a new kernel
Thank you

In short, you need:
Q5 Memory Manager: http://android.gval.biz/download/Q5_USB_Memory_Manager.apk
Module Loader: http://forum.xda-developers.com/showthread.php?t=1228605
usb-storage module: http://doomlord.sylvester20007.com/xperia_2011/usb_otg/v01/usb-storage.ko
You can then connect and mount USB flash drives (formatted FAT32) with a suitable USB-OTG cable.

Hi
a cheap wireless keyboard/mouse bundle works perfect with a cheap otg cable.
usb hub too.
Managed to use usb key with XTCrefugee explanations.
But, could we charge the battery, at the same time using usb devices?
arc S

otg with unsupported USB
Getting the same error message, I have Astro file manage.
Unsure how to mount USB drive.

Get this app, it does the job nicey http://forum.xda-developers.com/showthread.php?t=1389653
PM me if you would like a copy...to test out

Thanks for responding, but I see the linked app requires rooting etc. There appears q5 but that's not on plaststore. Would upgrading to ICS be solution or a problem. What would you suggest?

When I had ICS installed still need to use some app to mount USB stick ... I have to say that Nokia N8 and other new Symbian devices have better support fot USB OTG ...

USB ports

Hey. I am about to buy the G TAB 10.1 . As far as I know there is an adapter that convert the charge port into a USB port. My question is, there is any USB hub for it , so I can connect more than one device to the Tab?

From what I've read it would have to be a powered hub I think.

I have ordered a USB adapter but there is only one out on the adapter, I will try it with a USB hub if it works I will let you know

my item has just arrived and works perfect with usb hub

have you been using a powered usb hub?
I am wondering how much the tab can handle, have a feeling that a powered hub would be wise?
Sent from my GT-P7500 using Tapatalk

Yes, use a powered USB hub. That gives you the ability to use external HDDs, which require more power than the Tab can provide on its own. Also, if you have a USB mouse (or bluetooth mouse) you can connect that up too. Works like a standard mouse.
As an FYI: if your drive is NTSF you will need additional support to get your drive to be readable by the Tab.

Q: Are you rooted, and are you using a custom kernel?
If yes, does the kernel support NTFS?

Yeah, so you have "2.6.36.4 - OC-VFPv3-d16_FP 1.4GHZ - Galaxy Tab 10.1" then, I reckon, since that's the date on the thread. That's what I'm using.
So you need to go to http://droidbasement.com/db-blog/ and cursor down to this:
HC 3.2:
lib-2636.4_ux_hc32.tar.gz (Kernel Modules)
Download: lib-2636.4_ux_hc32.tar.gz
Download that lib-2636.4_ux_hc32.tar.gz file. This contains the ntfs.ko module. Extract the ntfs.ko file out of it.
Oh, yea... copy the ntfs.ko file to "data/local/modules/". You may need to create this directory. I've never needed to worry about changing permissions...
(FYI - I use File Manager HD which gives root access and read/write access. It's free unlike Root Explorer.)
Then if you go to this thread: http://forum.xda-developers.com/showthread.php?t=1448933.
I posted (#2) about some support apps you will need (Terminal Emulator and a NTFS mounting app). Open the attached image file - this shows the commands you need to enter in Terminal Emulator.
Run the mounting app and you should be golden.
If you reboot you need to follow the process again from Terminal Emulator.

[Q] Is it possibile usb OTG?

Hi!
I tried OTG on my Wildfire (CyanogenMod 7.1) but, naturally, it doesn't work.
It recognizes the cable like a dock station and active the pen drive but doesn't mount it: can add an OTG support?
I also tried the Chainfire's app (USB Host Diagnostics) but it didn't say nothing.
Thanks.
Bye!

[HOW-TO] Enable OTG(USB HOST) on Galaxy SII

So after painstakingly searching around for an answer on how to get OTG working on the galaxy s2 running a custom ROM and Kernal with little to no help i finally figured it out:
You will need:
OTG Cable ( Micro USB Host cable) (store bough or home made work, i followed this link: http://highonandroid.com/android-howtos/how-to-make-otg-usb-host-cable-for-galaxy-s2-or-xoom/ )
A Kernel that supports OTG ( I'm using { and could only find } http://www.gokhanmoral.com/gm/2012/05/06/siyahkernel-v3-2rc1/ , there is an update to this kernal , but i have not tested the OTG support yet (May/7)
And last but not least, USB Host Controller APP : https://play.google.com/store/apps/details?id=hu.sztupy.android.usbhostcontroller&hl=en
Procedures :
1. Install the kernel by flashing it through CWM
2.Install USB Host Controller App
3. Restart phone
4. plug in usb device into OTG cable
5. Plug in OTG Cable to phone
6. TADAA
if you have any questions feel free to PM me or post a reply...
i had to change the steps from the link to make the OTG cable to make it work!!!
Homemade Cable Troubleshoot:
my cable was a samsung USB U2 cable, i dont know if this makes the biggest difference. but you want to short ( connect) pins 4 and 5.. one of the 2 solder points is the black wire from the usb cable ( ground) and if yours doesnt work with the pin he says to use, you can try plugging in a usb device into the cable and have the wire connected to the ground and simply probe the other pins until you find the pin that works! ( DO NOT CONNECT BLACK AND RED I REPEAT DO NOT SHORT BLACK AND RED, YOU WILL FRY YOU PHONE AND I TAKE NO RESPONSIBILITY FOR THIS, THIS IS YOUR WARNING!!!)

This kernel can work with Galaxy s2 duos tv gt-s7273T ?
I,m trying enable the OTG to my s2 gt-s7273T
This is possible? Using Jelly Bean 4.2.2 stock rooted
With busybox installed .
Please if possible help me

WOW! I have a faulty micro sd card so I could only backup to internal storage. Saw your post which reminded me I have an OTG cable that I use for my Note 4, I'm using CM11 and "hey presto!" CM11 recognizes external USB, no apps needed, I could/can make backups, Love my CM11
Glad I saw your post, Many Thanks, and Kind Regards!!

use otg without y cable!

I have found a way to use otg in s3 neo plus without the need of y cable or external power source. Otg device will get power from your s3! First plug in your otg cable (use normal otg cable not y cable) don't connect anything in the other side of otg cable for now. The go to terminal and execute this commant in super user mod.
echo "1" >> /sys/kernel/debug/regulator/8226_smbbp_otg/enable
you will hear a sound. Wait 2 second.now connect your usb device to otg cable. And you otg device will get power from phone. And when you are done using otg execute this code in super user mod
echo "0" >> /sys/kernel/debug/regulator/8226_smbbp_otg/enable
Don't forget to execute this code or your phone will not charge while connected to charger.
And i used otg using stock kernel.
If you face any problem or this doesn't work reply me i will try to help.
And if it works then reply and let others know.

Finally now I can use my OTG cable! ^_^

not working on stock rom
tried on s3 neo dual sim

yep it did worked, i just tested in my sgs neo + GT-I9301I running PHN latest Stock Firmware.
Thanks a lot for all the work and effort coz it's an awesome things that we'll be able to do that without external power.
the only thing is that, it's only ES FILE EXPLORER that can manage to find and give me access to my flash drive ... but the stock file manager, mixplorer, root explorer, don't detect the device at all !!!! so i was wondering if there is something special i should do.
otherwise for other non storage devices (mouse, keyboard, game-pad) get detected automatically

When you connect the flash drive you will get prompt for allowing es file explorer to use usb device. Don't click ok,click cancel. And if you have ticked use by default then goto es file manager app info and click clear default. Your usb device will be mounted by system (same as external sdcard ) you can check it in settings - general -storage. And one more thing if you flash drive is formatted in ntfs it will can only mounted by es file manager. System can only mount file system like vfat exfat fat32 etc. As far as i know.

Not working on my device at all. No sound nothing. And my phone is charging even without disabling. What's wrong

maybe I'm wrong but I think it's ur stock rom
to my knowledge there is no 4.4.4 ROM for the GT-I9301I, up to date stock ROM so far is only the 4.4.2 ! so I'm a bit curious

I tested with usb flash drive,external hard drive,zaza remote,mouse,keyboard and joystick and it is working good.
