[Q]Wireless usb keyboard

If you use a usb wireless mouse/keyboard do you need an externally powered hub. The keyboard/mouse is battery powered, so wouldn't you just need a micro to full usb adapter? Any answers would be appreciated
Edit: would there be any other issues (driver, etc.)
You need a Y-cable and to provide power for USB devices on WebOS in USB host mode. This video pretty much shows it all:

Are you looking to use a keyboard that has a wifi or ir dongle? I just tried a mk320 after powering the dongle with a powered usb hub, y connection usb and some usb gender changers. Nope, don't work (doesn't work for my hdtv, which supports usb keyboards either).
It's sorta a moot question anyways since you need a plug for the hub, isn't it?
I got the hp bt keyboard and that works fine, and is small enough to lug around, and has support for cards on the screen as well as Just Type.

[INFO]USB OTG on Mini/Mini Pro/Active/LWW

*This is only a reference/information thread for those who want to use OTG feature on our 2011 xperia phones, for your convenience.
(For that Sony Ericsson didn't tell you how to use that feature.)
Information for xperia mini, mini pro, LWW and Active.(since they share similar chipsets)
TESTED ON GB 2.3 Stock rom with wt19i.
1. USB OTG support is native on stock roms.
2. Almost every USB keyboard and mouse can be used with OTG.
3. Some special keys on the keyboard may NOT work(such as volume up/down buttons).
4. Key bindings may NOT work. e.g. Ctrl + C won't work in terminal apps such as connectbot or terminal emulator. Consider twice if you want to use keyboard for terminal.
5. To use USB flash drives, you have to use OTG helper from shardul_seth from:
http://forum.xda-developers.com/showthread.php?t=1588979
6. (with OTG helper) USB drives will be mounted @ /sdcard/usb_stick_1/ (or something similar)
7. USB hubs CAN be used.
8. Portable hard-drives can be used although it needs external power source.
9. Using these USB devices with your phone can DEPLETE YOUR BATTERY rather quickly.
10. Pen tablets won't work. (Tested device: Wacom Banboo)
11. USB card readers might NOT work. (Some do, some don't. I tested a card reader with multiple slots(MS Pro, microSD, SD) and my wt19i failed to recognize it.)
12. USB flash drives larger than 16GB might NOT work. (As reported from Taiwanese forums.)
13. Some USB joysticks will work, some won't. (No drivers for Android
I will keep testing USB devices though. Thread will be updated in the future.
Attachment is my own wt19i with an USB keyboard.
Preserved for future use.

USB joystick work like a charm, I've tested a thurstmaster 8 button on my mini pro!
@paacoo Thank you. Information corrected now.
p.s. Tested that Playstation 3 controller wouldn't work
Other devices
Hello all
I have tried WD self powered 1Tb HDD the trick was to connect a hub with double USB cable, one to the phone and the other to a battery or usb charger, worked correctly, I think I can browse all the drive content.
Recently I bought a multi card reader branded as Manhattan that support SD, micro SD, MMC, etc.., plus 3 usbs and worked. I can read my SD/microsd and read/write files.
Also I tried wireless (RF) mouse/keyboard branded acktec and worked great.
If you are interested I can tell you the product number.
@edgar0204 Thanks for your reply. I think I'll start a list for unsupported devices then

@aznrogerazn: I"m sure in that Android compatible only with HID devices. I"m unsure in that PS3 controller is HID-based, but take a look here:
http://www.codeproject.com/Articles/23634/Wired-PS3-Six-Axis-Controller-Using-USB-HID-as-Inp
@x.x.x.Peria The reason why Playstation 3 controller fails to work is that the phone cannot provide sufficient power supply. With proper programming and enough power, it is supposed to work. It can be used on the phone with bluetooth, however.

There are no hidden features on our phone.
USB OTG feature is known already on Live with Walkman, announced aswell on official white paper.
By default(and officially), OTG support exists only on LWW, but with certain workarounds, it is possible on other devices aswell.

Knowledge for homemade USB OTG cable http://forum.xda-developers.com/showthread.php?t=1092493
I don't found posts about atom bomb yet
I made a homemade USB OTG with the help of this tutorial, and works like a charm.
:highfive:
If I use an USB HUB with external power, it will work? My target is use an USB HUB with external power to supply energy for a mouse, a keyboard, a pen drive and my phone. Or just to reduce the battery consumption. I know HUB powered by USB works fine.
PS: with OTG cable, my homemade one: kingston pendrive 8GB works, lenovo mouse and keyboard works, leadership mouse and keyboard (with a nice number of special keys) works, Bright wireless mouse with usb adapter works, bluetooth usb dongle don't works (needs driver), and with a USB OTG cable you can recharge another phone haha. * I'm using ICS at St15i.
USB hubs with external power source is working as reported from Taiwanese forums. You can only use one flash drive on the hub at the moment though.

Interesting.
With powered hub, I connected a PS3 controller and reading the kernel log with dmesg, seems to be recognized and installed but don't works and starts to charge, without my phone at hub the controller don't charge. Other devices work normal, and the phone is not in charge mode :silly:.
If anyone have idea to tests, I think I can do for help.
Thanks for the thread aznrogerazn.
Can anyone confirm if this works on MiniCMSandwich Lite? I don't have an OTG cable but I'm gonna buy one if and only if, it's working. Gonna be a waste if it doesn't.
@GregyrioAxiaMagno PS3 controllers can be used on bluetooth mode. You can google the method if you like.

Thanks aznrogerazn, I have the Sixaxis app working good, is a nice app is it?
But, check this out, I have a nice news hahaha. I managed to work the PS3 controller by USB. So: I have a 7 ports powered hub, and it can be powered by usb also. I plugged my otg cable in Android and the cable at the HUB, then I plugged the power cable, after this, I connected the PS3 controller at HUB, the lights at the controller will blink if in charge mode or blink only once if the battery is full, and unintentionally, I hit the button with the PlayStation logo, and voilĂ : the controller works! I noticed what the touchscreen gets a strange behavior... I saw this same behavior when a friend used an non oficial usb cable to charge the xperia x8, an ordinary cable... like if the touchscreen got messy. But the controller and the rest works. So give a try, with a powered HUB and plug all, then hit the PS logo. I noticed also what the usb host mode can be disabled sometimes, is just restart the phone or plug a mouse or something to get work again.
I will make a video maybe or take some photos in another thread.
EDIT: The strange behavior of the touchscreen is caused by the power, I mean, when I connect the power cable. I think this happens because there is no filter of energy in the circuit. Maybe a high quality HUB solve the issue. The touch screen become normal again when the ordinary power cable got disconnected.
EDIT 2: About the crazy touch see this http://forum.xda-developers.com/showpost.php?p=10206146&postcount=8. The power cable of the USB HUB is an ordinary 5V 1000mA, thats is the problem.
EDIT 3: I made a video but I won't open a new thread xP

[Q] MHL & OTG simultaneously on Xperia Z Ultra?

I bought a USB hub which sports an MHL and OTG (See attached) .
On my xperia z ultra the MHL works fine but when I plug the airmouse into the OTG the phone doesn't detect the mouse.
I tried to unplug the MHL (removed HDMI cable) and use only the OTG feature but the phone doesn't detect the mouse. The phone doesn't detect any USB storage device as well.
The MHL and OTG feature is a built-in option in Xperia Z Ultra so it should output as MHL and and detect airmouse at the same time, but it doesn't work.
Can anyone please help me how to get this done?
Awaiting for replies anxiously

I would honestly go with chromecast, it's your best bet to use the mouse as well.

The chromecast will not support the airmouse that I have. There is a small usb donlge for the mouse which needs to be connected to chromecast. I see there is no option to plug a USB device into chromecast, right?

I think he's suggesting that you connect your mouse to the phone and then cast the phone screen to the Chromecast.

I already mentioned that the airmouse is not detected by the phone; if it was, the issue will be solved because the MHL already working fine and output to big screen tv is fine.
My questions are:
a. Whether it is possible to use MHL and OTG at the same time?
b. My phone xperia z ultra is not detecting any usb devices such as pen drives, regular pc mouse or the airmouse. How do I get that to work?
Further update: I was able to get the OTG working and the phone detected the airmouse, however I could only use either of the MHL or OTG but not together. Any ides how to get the MHL and OTG work together?
How'd you get the otg to work? I bought 2 of them. But my Xperia Z ultra isn't detecting it.

Its easy. First of all OTG doesn't require any additional power to be connected to the HUB, you need to remove that. Second, plug in hub into the phone, then plug the USB device into the OTG USB slot of the HUB, then keep pressing the switch on button until it becomes "Blue". Please make sure you don't have any external power connected to the adapter at this point.
No I was talking about otg to the phone. I had no issues with Samsung but my phone doesn't detect the cord when I plug otg in it says USB connected, but when I hooked up the ps3 controller it had issues of not being recognized.
You can't use both MHL and USB OTG features at the same time because Sony Xperia devices (including the Z ultra) use 5 pins MHL connectors as opposed to Samsung devices (since the Galaxy S3) that use (not standard) 11 pins connectors for this very purpose (which is why most MHL cables require the use of an adapter on these)

USB C to A OTG causing a weird bug on my Tab S6

I'm trying to connect my Tab S6 (SM-T867V) to my Logitech mouse, but as soon as I connect the OTG cable to the Tab, even before the mouse controller is insterted, I get a notification that says USB connector connected and then it switches to USB connector disconected and just keeps flipping between the two notifications every few seconds seemingly endlessly. I tried the otg cable with my Note 9 (SM-N960U) and it works perfectly fine with my mouse. The Tab and Note prompt me with charging/file transfer when the otg cable is hooked into the Note and connected to the Tab via a usb c cable so that seemed to work fine. The tab also works normally when charging and using a usb c to hdmi adapter, so I don't think it's a port issue. Both devices are on One UI 2.1 and both have USB 3.1 type C 1.0 reversible connectors, so I'm really confused as to why I'm getting this bug. If anyone has a solution, I would greatly appreciate it!

My Goodness that is trash! i'm suprised that it works on your Note 9! Mate purchase a uGreen or any decent USB hub! Plus make sure it's got (PD) Power Delivery port!

I didn't think about PD making a difference, but maybe you're right. My usb c to hdmi does support PD, but the power wasn't plugged in when I tried it and it still worked tho ?
But either way, I ended up purchasing a bluetooth mouse instead just because it's more useful to have one for my tablet rather than unplugging my laptop's every time I take the tab somewhere. I will keep this in mind for if I need to add more accessories later, so thanks for the info.
