[Q] Micro USB to USB Converter, mouse and keyboard simultaneously

Is it possible using this kind of converter to connect simultaneously a mouse and a keyboard together to the phone ? (for example using a wireless set mouse/keyboard or a usb splitter).
Can the phone provide the power to work on both devices ?
Maybe if it was possible to charge the phone somehow using the same cable ?

I want to connect the phone to a tv using hdmi cable (adaptor) and control the phone from distance using a wireless keyboard/mouse.
thanks

I would be interested in this too. I saw EVO 4G used as a desktop computer - http://forum.xda-developers.com/showthread.php?t=1038840 but he used bluetooth mouse and keyboard and the only thing connected to its micro usb port was hdmi cable. I would rather use some kind of usb hub in order to connect these 3 devices to the micro usb port in the phone and even charge it all at once. If anyone knows if it is possible please share your knowledge

Yes, you are right about Bluetooth. I believe it's the best solution (but more expensive) because when connecting the hdmi adaptor no other ports remain for other usb devices. Also hmdi adaptor charges the phone (for example BizLink MHL to HDMI TV-Out Adapter)
thanks

You might be able to run both USB mouse & keyboard; try using a keyboard that has a USB port or two on it, then plug the mouse into the keyboard's USB. Power may be a problem; the SGS2's USB connector isn't going to provide anywhere near the 500 mA in the USB 2.0 spec.
Of course, if you're using the USB, you can't use the MHL/HDMI, and vice versa -- the connector modes are mutually exclusive. If you have to have HDMI output, you should be able to use a BT keyboard and/or mouse.

HOWTO: Logitech F710 Wireless Gamepad?

I have a Logitech Wireless F710 Gamepad that I'm trying to connect to my Nexus 7 (2013). ... The gamepad comes with a USB dongle, that I've attached to the Nexus 7 via this USB OTG adapter. Unfortunately, the Nexus 7 does not react in any way to the USB receiver being plugged in or removed. Any suggestions? Does the USB OTG adapter have to be powered by external source? Or, did I get a flaky USB OTG adapter?
If someone can help me get this working, I'll turn this first post into a more traditional HOWTO for future readers.

[Q] If I use a usb hub, can I attach an ethernet port, and have the device charging?

Title says it all, has anyone tried this?

From what I've read (and the other threads on this topic) - no it can't be done.

It can't be done my friend

I got it to work

I used the following and plugged into my TV usb port and had ethernet (verfied with WIFI shut off) and it was charging.
USB 2.0 Ethernet adapter - <amazon.com/gp/product/B003VSTDFG>
OTG with power - <amazon.com/gp/product/B00C452XFO/>

Yup, this now works great for me too! :good:
I bought the Ethernet adapter Nvidia Recommends (same as browncoatdave's)

And just whatever Y cable could find that didn't look uber cheap.

4) Smart Touch Mini USB TouchPad Keyboard

6) Charging cord
I am charging the battery with ethernet, keyboard and mouse plugged in.
No Problem. But this is also after the kitkat update which added the charging while ethernet is plugged in.

Did you plug all the devices in a particular order? I noticed that if I plug in my charger AFTER I plug in the OTG cable into the shield, then it is not charging. But when I plug in the charger into the OTG cable and then plug it into shield, it is charging.
Is your hub powered? What exact model is it? I am asking because I have very similar setup to yours but the shield does not detect USB devices connected to the hub - it's this one: http: // esperanza . pl/esperanza-usb-2-0-hub-4-porty-ea116,182,437.html
I can connect one usb device directly to OTG cable and it works, but when I connect a hub, it no longer works.

There is a cheap way to do this if you have the soldering skills, and are willing to try it.
Get a cheap USB "Travel" hub.
Open it up, and replace the Upstream USB cable with an OTG cable (A scrap Micro-USB cable may or may not work. The connector must be Properly wired for OTG).
Remove the main power diode in the USB hub, and solder jumper the 2 pads where it was. A Multimeter in continuity mode can help you find the right component, but it takes some experience. There usually is not much in a cheap travel hub, so I can usually find them just by looking, but like I say, only try this if you have the experience, and you know what you are looking for.
Power the hub through it's 5V power jack (if it has one), or you can add a power only micro-USB socket. (Only connect the (+) and (-) power pins, do not connect the data lines. Connect it to any one of the Full size USB port's power pins. Observe polarity.)
Voila! You now have 4 Full size USB ports, it will charge your device, and provide power (Up to the rated power of the AC adapter) for your USB devices.
I did this years ago in the Nokia 770 days. It was one of the first consumer devices that supported USB OTG. Article still exists here:

Would this work?
Would this: SODIAL(R) Micro USB Host OTG Cable with Micro USB Power plus this: Anker® Unibody 3-Port USB 3.0 and Ethernet Hub
Give me the ability to charge tablet, use Ethernet and additionally connect USB mouse and keyboard, and possibly charge Nvidia Game Controller?
Or would it just be a waste of time and money

Can't use usb otg feature when usb is connected thru a magnetic cable adopter. Help!

So I recently bought a magnetic cable adopter, It has two parts an android micro usb head and the body where it can connect to the usb head with the use of magnet and the other side is a micro usb port the body also has a led indicator.
Given that my phone is usb otg capable, when I connect my usb to the micro usb port at the body of adopter my phone can't read it.
Is this a hardware problem where the magnetic adopter is not capable of reading other devices eg. Usb, mouse, keyboard etc. and only supports charging?
Or can I still use the usb otg features by using a 'usb otg cable Y'?
Or is there other way?
Sadly I can't try usb otg Y since I haven't bought any and want to make sure it will work before I buy.
Feel free to ask more information if it's not sufficient enough. Thanks!

OTG + Magnetic cable
Same problem but at least I know that OTG can (should?) work through a magnetic cable as I have another device on which it does.

USB Mouse?

I know people have talked about using a Bluetooth mouse with the Tab S4 in DEX mode, but what about a USB mouse? Would it work with a USB-C wireless mouse or with a standard USB mouse with a USB-C adapter?

It should work just fine with a standard USB mouse as well. I used a USB Type C otg cable to use my usb nouse until my bluetooth one arrived and it worked well, I just had a dongle hanging off the side of the tablet.

I've been using a wireless logitech keyboard and mouse (with the usb unifying thing), connected with an OTG usb cable.
They work very well. They also work with the android phones I've had. It's kind of ideal. I don't often need a keyboard and mouse, voice recognition works perfectly. But on those rare occasions it's super easy to hook up.
One thing, sometimes the developer options for 'usb connection type' need to be changed to 'midi' to get it working. Sure beats the heck out of overpaying for a specialized keyboard for the device, which I almost would never use

I have been trying to use a Logitech K400+ keyboard with my Galaxy Tab S4 using the usb dongle with a USB C to USB adapter, and it does not connect. A wireless mouse with dongle works perfectly though. Any suggestions ?

You need to pair the mouse/keyboard with the USB receiver first on a PC, then from then on it will work in any android device.

I tested my CORSAIR - M65 PRO Wired RGB Optical Gaming Mouse using the USB-C adapter that came with my S9+ and it worked. RGB lit up and everything there was no setup required. Simply plug and use.

I'm using G602 Logitech.
It's a wireless mouse but not a bluetooth one.
I connect it with UGreen USB type C Hub to do presentations

Does anyone know if a usb mmo mouse like the Cosair scimitar will work? And will it detect all 12 side buttons as num1, num2, etc?
