OTG through a HUB

Hey! So i managed my S2 to work with an OTG adapter. Now it recognizes Flash drives, USB mouse and keyboard as well. My problem is though, that i'd want to use both the mouse and the keyboard simultaneously, and later on my tablet as well.
I've got a USB hub which was pretty cheap i guess,
ht tp://itmedia.sk/item-images/other-usb_omega_hub4portSTARpowercapable/it6818_2.jpeg?nc=032
When i connect it to the OTG adapter it lights up, and if there's a flash drive attached to it when i plug it in, the phone recognizes the flashdrive without problem. As soon as i plug in a second flash drive, the light goes off from the HUB and both of the sticks get unrecognized. Also, the mouse nor the keyboard works through the HUB somehow..
I need to buy a specific hub with OTG support or a power hub perhaps? Could anyone help in this? I looked over google and stuff but people seemed to say different stuff at almost every site.. Thanks!!
My Galaxy S has stock 4.0.3 rom with the Syjah S2 4.1.4 Kernel

Oh well that's quite interesting. Then you're saying this piece of video could be fake perhaps?
Since i can post links yet, search for this on youtube: USB HUB Support On GALAXY S2
Check the very first video.

I'm convinced that the every phone can handle only one device connected at the same time.

Well, it surely doesn't seem that way, that's why i was asking, since it's possible.

Weird.... i got sgs2 and 4-port usb hub and when i connect 2 pendrives to hub and hub to phone everything works good (i see UsbDriveA and UsbDriveB). If your hub have dc input you can try connecting power supply to this hub. Maybe this hub isn't compatibile with your phone.

Help , need to get OTG and MHL working simultaneously !

Hi guys,
My galaxy nexus screen has been cracked and it does not respond in 75% of the screen.
I bought a MHL to HDMI convertor on amazon and luckily got the phone UI to show up on my TV
Now since the touchscreen won't work , I need to connect a keyboard or mouse via USB OTG and use it for navigation.
Problem is the Galaxy Nexus has only a single microUSB/MHL port combined into one.
I have no idea how to split the output from the phone to connect to a USB OTG cable and MHL to HDMI adapter simultaneously !
Any help will be appreciated,
The phone is not rooted AFAIK , but may be I'm not sure. It was running Android 4.1 JellyBean when I dropped it on the floor
The phone does show up on my Windows PC and I have copied the photos off it. But I still want to copy contacts and SMS messages.

You tried just using something like Android Screencast from the PC (USB debugging is needed)
Also, some MHL adapters have a USB port in them, for power. Have you tried getting a crude micro USB splitter? Like this one? http://www.replacebase.co.uk/micro-usb-female-to-2-x-micro-usb-male-splitter-2392-p.asp#.URk59JGYOBs
Not guaranteed that would work though. Also, a quick google of what you want brings up some others with the same issue, have you tried to see if any of them have succeeded?

Good news
I had a spare galaxy nexus in the office and I gently took the screws of both the devices , and just swapped the displays so that I could quickly turn on usb debugging , backup essential stuff and also turn on bluetooth.
Thanks to some assembly videos on youtube ! will share some pics soon

USB OTG + USB HUB to connect A Mouse and Keyboard same time

Greetings Guys, I bought an USB OTG Cable, which works great on mouse,keyboard and pen drive.
My only ambition is to get it working with a Mouse and Keyboard at the same time, so I can use my mobile as a portable netbook like for work while im outside of home.
I have at the moment an USB OTG Cable, and a low power mini mouse and portable keyboard also an USB Hub with two ports, which can use external power source.
The thing is my note can see each alone, cant see the HUB and the devices connected, even with the external power connected to the hub, what I can do to solve this? thanks

Install USB OTG helper app (needs root), you can try to get some debug info from there.

Check this: www_leicke_eu/en/products/DS40538. I found it while looking for a usb hub that will permit me to charge my note 10.1 when using otg cable with mouse. Just replace _ with dots.

[Help] OTG cable problem

Hello, i have bought a OTG adaptor but when i connect a USB pen to my Sony Xperia S it doesn't do anything.
I have also tested:
- USB pen FAT32
- USB pen NTFS
I know that this adaptor is working because the store owner tested it on a tablet and it worked.
Stange thing is that i tried to connect to a zte blade, Galaxy Gios and nexus 7 and it didn't work as well....
However when i connect it to the computer the adaptor works...
Stock .55
No root
Can someone advise me?
Thanks

Root your phone and download USB OTG Helper from the Play Store.

I have many FAT32 USB flash drives that work fine with my XPERIA S no problems.
I have not confirmed this myself, but it is possible the amps provided by the Sony XPERIA S(LT26i) could be as low as 100mA.[citation needed]
Can't find any documented specs for XPERIA S and USB power supplied and/or USB flash drive which also has a known documented amp draw for reference.
I'd really quite like to know what amps the XPERIA S USB port provides.
I have a USB thumb drive that doesn't work on my XPERIA S namely the HP v165w 8GB (FAT32 formatted)
It just comes up with a big red warning triangle saying, "USB Power Consumption error"
However the USB thumb drive HP c330w 8GB does work (NTFS formatted)
Many other SanDIsk FAT32 formatted USB thumb drives also work fine. Namely the SanDisk USB 2.0 Cruzer Facet 32GB
I have downloaded Paragon exFAT, NTFS & HFS+ which allows me to successfully mount NTFS formatted flash drives on my root'd XPERIA S.
My 'Desktop' FV-1 Android box with three USB ports/HDMI etc, mounts anything and everything, including the HP v165w 8GB USB thumb drive. So it just means no two Android devices are equal in design and power.

it should work anyway? I've seen a few shots and youtube movies where the USB on-the-go was working on an XS!

连接U盘需要安装一个USB存储管理器的软件(此软件需要root权限和busybox).插入OTG和优盘之后可以看到优盘的灯亮了.之后再点击连接.
这样就可以在SDcard\usbStorage 里看到优盘里的文件.
你也可以连接一个集线器.这样可以连接鼠标键盘之类的.如果你要连接功耗比较大的设备,这样就需要一个带电源的集线器.如果动手能力比较强的话,还可以直接在OTG线上剥开接上电源.
希望有懂中文的....!!!!Hope someone will Chinese!!!

Connecting U disk need to install a USB storage management software (the software requires root permissions and busybox). Insert OTG and USB flash drive's lights. Then click connect.
The USB file so that you can in SDcard \ usbStorage see.
You can also connect a hub so you can connect a mouse and keyboard like if you want to connect to a large power equipment, so that you need a powered hub. Strong practical ability, but also can directly plug in the power in OTG online peel.
this is what google translates for me! pretty weird to read like this. but maybe we can figure it out?!

In my honest option, I agree with SNYXPR, there should be no requirement for additional software on a standard build XPERIA S(LT26i) when using "supported" FAT32 formatted USB storage.
If the FAT32 formatted USB flash drive you have attached to the XPERIA S meets the power requirements you should be fine.
No software I know of is going to boost the power supplied by the MicroUSB port and at best, any application for USB storage is only able to support additional drive formats like NTFS etc.
I've had/have USB flash drives, Logitech Unifying Mouse/Keyboard attached without problems.
I've got a Galaxy Note Connection kit Model: DR03-S2 and that works fine and I'm able to read/write SD cards, MicroSD cards and USB flash drives using it without problems(one attached device in use at any one time).
If you go to the next step and use a powered USB hub, then a wider array of devices can be used with the XPERIA S as the USB hub is providing the power to connect the device. This includes USB printers and FAT32 formatted USB 80GB plus HDD (both IDE and SATA) etc. Also all those FAT32 formatted storage devices that said the XPERIA S did not meet the power requirement work too.
Remember the XPERIA S only support FAT32 formatted storage by default(natively).
As part of my desktop setup I have the following connection.
Sony DK10 dock plugged into a Aten USB switch which is connected to a powered USB Targus 7 port Hub.
This gives me access to USB mouse/keyboard, USB flash drives or USB HDD of any size, printer, SD card reader on my DELL U2410 monitor and etc.
Then it's just a button press to (USB)switch back to my Notebook, Desktop PC and any other device connected as part of my desktop environment.

Thank you for the replies, i think root is not required since i have seen a vídeo made by XperiaBlog that just connects a USB pen drive to Xperia S and it just works. I have tried a Kignston 8 GB and it doesn't connect, not event to nexus 7 ...

Second USB device

I tried connecting a USB keyboard using an USB OTG cable, but I didn't get it to work. The other USB port is in use by my external harddrive.
Is there a possibility to make the keyboard work?
Can immagine more people want to add a second USB device to their OUYA...

You'll need to buy a USB HUB (Get a powered one to future proof all your USB needs, you can get a USB 2.0 Hub pretty cheap). This will allow you to hook up at least 3 USB's to the OUYA. The Micro USB won't work for things such as hard drives or HID devices.
In the future, please use the search function before posting as this has been talked about in many other posts.

I have a 4-port hub and it works fine connecting 1 storage and 3 other usb devices

I had this issue where only one harddrive could be used and If you have a harddrive with 2 partitions ouya wont mount it. Luckily I found an app called usbotghelper which does all the above I mentioned plus read and write and ext3 support. I wish it would get submitted to the ouya store so I could use the paid version that will mount on startup.
