USB Host/OTG without doc

For the "old" Atrix 4G, there is a thread regarding USB Host, without a dock.
http://forum.xda-developers.com/showthread.php?t=997187
Can the same be done with the Atrix 2 (buying the USB hub and the OTG adapter)? I assume getting WebTop app requires rooting? Can the USB OTG still be used without rooting?
If not using WebTop app, is there any advantage going this route, versus just using a bluetooth keyboard/mouse ? Maybe just so that I can copy files to a disk key?
I'm just envisioning using something like this while visiting a relative or staying at a hotel - hooking the phone up to a TV, to be able to do things.
Thanks

Yes, it works on the atrix 2. I've gotten usb mass storage, keyboards and mice to work. All before the root was available.
The only problem I have with it is minecraft pocket edition doesn't support remapping the input to keyboard+mouse.
Oh- also I had to shave a little plastic off the side of the OTG adapter for the HDMI cable to fit at the same time.
I would suggest going the bluetooth route unless you need usb mass storage or usb ethernet.
The mess of wires can get pretty bad...

Hmmm... I need help here.
I have this set up:
- Micro USB On-The-Go Host OTG Adapter
- The USB male split into two cables: power ( 5v + GND) and data (d+, d- , GND)
It's fully functional, on my Touchpad running CM9 and WebOS. But doesn't work on my atrix 2.
What the thread on the OP is suggesting is you have to put the 5v on the data cable too ?
-------------------
yeah, just did it. It works and still charges the cellphone! \o/

When I tested it, I used a hub. Thankfully the hub's included cable has a third lead coming off with only 5v and ground connected, so it was a perfect match.
I've spliced up a cable to test the way you have it. Unfortunately, even with 5v+gnd hotwired, I haven't been able to get it to work without a hub between the usb otg adapter and the usb device.
This suggests that Motorola only really wants you to use usb host mode with the official lapdock or docking station, etc.

Strange... The modified cable worked fine to me.
an usb keyboard worked with the cable and even an unmodified usb hub.
So you have a hub with a second cable only for power? Do you have a link ?

Just tried it and you're right about the keyboard. It works when connected directly.
Till this point I had only been trying USB storage and mice.
This kinda makes me think this is just a software deficiency that could be worked around.
As far as the hub goes, it's just a 4 dollar hub I found at goodwill.
After a little research, I found out what it is but it's discontinued of course. Any usb hub should work, the trick is the Y cable.
The hub linked to on dealextreme in that Atrix thread is wired in a way analogous to this.

Can you guys explain a bit more about these modified cables and the Y adapter cable? Like, exactly what cables do I need, and what modifications need to be done.
Thanks!

To the Atrix act as a host all you need is that OTG adapter metioned earlier. But, mobile devices don't provide power to "guest" devices. So, you need to power the usb device with a external source.
You have 2 options:
- Self powered HUB. Actually that's not enough. You'll need to power the USB pin 1 on the cable connected to the atrix to active the Host mode. That's why that hack (wire soldered) on the atrix 1 thread.
- The Y cable. As I described before is a normal USB cable powered by other USB cable. Ex: http://www.amazon.com/Apricorn-Power-Adapter-Cable-AUSB-Y/dp/B000JIOHDE
On our scenario, one will provide the data communication and the other the power. So, the data cable you will connect to the atrix and the other to a PC or the atrix charger.
I hope I made myself clear in a not so bad english.
If you buy a Y cable, you'll only need the OTG adapter ( http://dx.com/micro-usb-on-the-go-host-otg-adapter-pair-50774 ) and any usb hub.
If you want to make the cable, only 2 USB cables.
If you want to modify an USB hub. Just any hub and a cable.
I'm modifying an USB hub, I'll post pictues and I get home.

Rechargeable battery powered usb hub with otg cable
I was able to make myself a battery powered usb hub with an otg micro end on the cable and its rechargeable. All for $10

Using the USB host adapter and a y splitter, which I power via USB to AC adapter I can use a keyboard / mouse. I am unable, though to access a USB memory stick or the like. Looking at the Atrix 4G forums of people who did similarly - pre the latest firmware, the Atrix 4G needed to use manually mounting - which I assume needs root. But, the latest Atrix 4G automounts. But, I have a Atrix 2 with the latest firmware... and no automounting. Any ideas?
Thanks

I have the Micro USB OTG Adapter ( product B005N55WHI on amazon ) + the Y cable ( product B003HHK576 on Amazon ).
I put on the red plug of the Y cable a portable USB battery (phone detects it and is charging).
On the end of the Y cable I have my camera.
When I check with USB Hostdiagnostic it detects the USB device (my camera) but not the app I want to use it with. The USB host diag shows that at Android API Claims support and Classes found is NO and Device detected is N/A .
What am I missing?
Update:
USB Mouse and keyboard works.

You need to use a usb hub between the splitter cable and the usb drive.

Anyway to get USB controller to work?? the generic dual-shock II clone.

i have drawn a simple diagram using paint which i have understood by reading through out this thread,
is it correct?
and i have spotted a question in the diagram which asking for a Y splitter. is this is the one which called Y splitter or something else?

You need a kernel with USB OTG support. SebastianFM's kernel, here
The Micro Usb connector has 5 pins inside. In standard data cables that comes with the phone, only 4 pins are used. When the unused pin is connected, the cable becomes an OTG cable.
Pin 1 : VCC pin, +5V Power supply, COLOR : RED
Pin 2 : D-, Data- Signal line, COLOR : WHITE
Pin 3 : D+, Data+ Signal line, COLOR : GREEN
Pin 4 : This is the pin which is not used in standard data cables, we will "SHORT" it to pin 5 to make an OTG CABLE
Pin 5 : GND, Ground Supply
These colors are UNIVERSAL in USB connectors, this means the red is always VCC, black is GND and the other two always perform the same action, unless somebody deliberately connects the colors to different pins
Warning : I'M NOT RESPONSIBLE FOR ANY DAMAGE ON ANYTHING. (YOUR PHONE, DATA CABLE, USB CONNECTOR, HOUSE, FERRARI ETC.) IF YOU AVOID ANY SHORT CIRCUITS, AND COMPLETE ALL THE STEPS AS I EXPLAIN THERE WILL BE NO PROBLEM. AND THIS TUTORIAL SUPPOSES YOUR PHONE AS AN HTC PYRAMID
IF YOU ALREADY HAVE AN OTG CABLE, YOU DON'T HAVE MUCH TO DO.. YOU GO TO 2
1 ) THOSE WHO DON'T EVEN HAVE AN OTG CABLE START HERE -THESE STEPS REQUIRE EXPERIENCE ON SOLDERING
What you need:
1)A "MICRO USB B" head. (Can be obtained from an old charger, data cable)
2)USB A Male to USB A Female Connector : These Connectors
3)USB Cable (A short one is enough)
4)A sharp knife,etc.
5)Soldering Kit
6)Hot Glue
7)Tape
8)Some experience on soldering
STEP 1 - The first thing yo need to do is to SLICE two sides of the plastic cover of the micro USB connector, and clean the glue under it. You will need the plastic cover later!
HAVE A LOOK AT THIS VIDEO TO UNDERSTAND CLEARLY
STEP 2 - Once you reach the pins under the glue, you can get your soldering iron now to start soldering.
Matching cable Colors and Pin NUMBERS AGAIN : 1-RED, 2-WHITE, 3-GREEN, 4-NO CABLE, 5-BLACK
STEP 3 - If you did soldering (or cables are already soldered to pins--if you're using a data cable) now you need to SHORT CIRCUIT the EMPTY PIN (PIN 4) and PIN 5 (Black Cable). You can use a very short piece of cable to do this. NOW YOU HAVE A "MICRO USB B" CONNECTOR WITH OTG SUPPORT.
STEP 4 - After you completed the soldering, and IF you are sure you made no mistakes, apply HOT GLUE. Wait for it to get cold and hard, then cover it with the plastics you sliced before. You can use cheap quick glues to do that. How the connector looks after all depends on your creativity and ability
STEP 5 - Cut the cable of the USB A MALE to USB A FEMALE connector at 20-25 cm from the female connector. Now you can connect USB Female A connector, Micro USB B connector, and USB Male A connector
STEP 6 - First connect the matching colored wires of USB FEMALE A connector and Micro USB B Connector (red to red-white to white-green to green-black to black). Now you've a working OTG cable, but without an external power connector.
STEP 7 - To connect the "USB A MALE" connector,which will be the external power to the OTG, you only need to connect red and black colored wires of it (the +5V and GND wires) to the matching colors of the other two cables you connected before ("MICRO USB B" and "USB A FEMALE"--The OTG CABLE you've made). If you connect white and green wires of "USB A MALE" connector, YOUR CABLE WILL NOT FUNCTION. DO NOT CONNECT WHITE AND GREEN WIRES OF MALE USB A CONNECTOR.
You can use soldering iron to strenghten the connection between wires. Or you can just use tape. It's up to you. Just be sure that there's no possibility of short circuits.
You need to use tape for each color of wires to prevent short circuits.
AGAIN : Be sure that you've made all the steps carefully and correctly, and avoided any short circuits before using your cable. The only short circuit should be the pin 4 and pin 5 of MICRO USB A connector
AND YES IT'S DONE, YOU CAN USE YOUR CABLE NOW
2 ) THOSE WHO HAVE USB OTG CABLE AND JUST WANT TO CONNECT AN EXTRA USB POWER CONNECTOR--START HERE
You need :
1)MALE USB A CONNECTOR with 100-120 cm cable -- lenght depends on you, should not be much longer than 2 meters(standard usb connectors) (U can get it from any data cables, old USB mouse cables, controller-joystick cables.. Just cut the cable at 100-120cm from the connector)
2)Your OTG Cable
3)A Sharp Knife etc.
4)Tape
5)Soldering kit (optional--if you want to strenghten the connections of wires)
STEP 1 ) Cut the USB OTG cable in the middle.
STEP 2 ) You only need red and black colored wires of "MALE USB A" connector, which are +5V and GND.
STEP 3 ) Connect the matching colors of your OTG cable again, but this time also connect the "MALE USB A" connector's red and black wires to the matching colors. WHITE and GREEN wires of this connector should not be connected. Otherwise the cable WILL NOT FUNCTION.
You need to use tape for each color of wires to prevent short circuits.
BE SURE THAT THERE'S NO POSSIBILITY OF SHORT CIRCUITS AND YOU'VE MADE NOTHING WRONG
You can also connect SHIELD WIRES of each cable to each other. But i'm not sure what actually it does. If you test it, please post your experiences.
What is Shield Wire:
The USB cables actually also have "SHIELD WIRE". My 2.5" external LG HDD does not work with the cables without shield wire, but many products should work. Shield wire is the one silver colored wire surrounding the other four colored cables and aluminium foil. It is connected to the outer silver colored parts of the connectors. I'll update this post after testing if shield wire needs to be connected,too. For now i use my cable without it, but my hdd does not work. All others (usb mouse, usb flash drives, joystick, hub, my sony e443 Walkman , PS3 Dualshock 3 Controller etc.) work. I don't know if the reason why my hdd does not work is that wire. Will test it by monday and upgrade my post.
My own made cable is attached below, not perfect, but good, working fine
Thanks to SebastianFM

Sir, I have done exactly what's in the guide for having an otg cable and attaching a usb male for external power. But I am facing a little problem and that is when I connect power to usb male first, but without attaching to my Tab, and I connect my pen drive first, it doesn't get powers as the led doesn't blink. But it does blink only at the moment I insert the pen drive into the female usb. Now I did a different thing, I connected micro usb port to my Tab, then my pen drive and then the power male usb cable, it works fine. But I am getting confused that is my pen drive getting power from that attached usb male.

I sometimes face the same problem when i want to use my external HDD device. But its not a problem at all. I think usb male power has some difficulties on supplying enough power to both phone and HDD. It works by connecting HDD first, then USB male to power, and then phone. This order may change according to your charger, device, and phone

You may have damaged it? You sure you connected all the wires correctly? Because all these colors are universal and there shouldn't be any problem once everything properly done.

Question.. on another thread someone mentioned using a 100k ohm resistor between pins 4 and 5 for "charging" while using OTG mode. Any particular reason why you didn't include this? reading your comments it appears like its not required but just curious.

Some newer phones (like s3) do not charge while using a Y cable. For ex. the controller is connected to Y cable and it works with the phone, but the phone is not charged although the power is also connected to the Y cable. This is annoying because playing games consumes battery ver quickly I (am not sure but) think the reason for including a 100ohm resistor is to enable charging and host mode at the same time on such phones. On Sensation there's no need for it because this cable just works perfect for Sensation. Charges and hosts at the same time.

Great info and instructions, now the only answer to the burning question I have is.......
..... Has anyone... Anyone! at all! managed to make a OTG Cable with a USB power plug, using the correct 'resistor' value while still using the phones stock 'unrooted' JB 4.1.2 rom, and stock 'kernal' not patched in anyway for the Samsung Galaxy Note 2.
Although there are products on eBay said to do this job, and have been reported to work by others, the sellers that offer these adapters are all based in China, and will not trade/sell to Europe at all.
If anyone has a solution around this problem, sharing there knowledge would be great.

Nokia OTG cables are not Micro B connectors but Micro A. So The OTG cable for N8 will not fit into our sensation or other android phones. You can see the difference between Micro A and Micro B here :

U can use Chainfire's StickMount app free on playstore to see if your flashdrive is connected. If it shows no drives connected then check your connections, optionally using a multimeter. Check the 4th pin is shorted to 5th one.

If you have a multimeter it will be good to test of course. If you're sure that u coonected all wires without any wrong short circuits there will be no problem, no damage for the phone

Thank you for the recommendation, I was meaning to buy one for some time, just slipped my mind a time or two !

was thinking OTG and hub , but what about a together ?
getting my nexus player tomorrow , and realized i only own right angle OTG , considering the below OTG/hub , i know it requires a power adaptor , but i am a junky for ports and power .
any owners see a issue with this ?

A good powered hub is near a must for a device like the NP as there are so many uses for peripherals: hard drives, keyboards, mice, USB keys, Flirc IR controller, usb ethernet, etc. I highly suggest getting a decent powered hub with a lot of ports and a good track record. Monoprice sells a pretty good powered 7 port unit that has great reviews (I have four all over my home) and is relatively cheap:
http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=5328&seq=1&format=2
The hub you were looking at above is limited to 3 ports and doesn't come with an a/c adapter. I'd look elsewhere, imho.

So far I have had good results with a bus powered hub. Granted, it's not going to work for a bus powered power hungry accessory, such as an external hard drive. But it powers my wireless dongle for my F710 and a USB flash drive just fine.

I've noticed my Logitech K400 had some pretty bad range issues when the receiver was connected directly to an OTG cable, but when I use a powered hub it's working great. So, it may be worth considering, if you notice any problems with an unpowered setup.

Just want to update. This cord works fine

I have this one and it works great. I broke my rightangled one trying to force it to fit with the hdmi plugged in...glad they are not expensive.

I bought my right angled USB OTG before I got the unit and also had some trouble getting it in there. The problem was that the power cord was in the way. I resolve it by simply plugging the USB OTG in first and then inserting the power cord.

30 seconds with a razor blade, and I simply cut away the right angled part all together, and hot glued it into a straight otg

You are lucky because yours bends towards the power cord and not the HDMI cable like mine did...there was no way of having both installed at the same time.

Ugreen USB C hub

Ugreen USB C hub
Hi guys,
I recently got this nice hub, so I thought I could share it with you, because it is really cheap compared to Samsungs' original parts. I got it for around 20$ from someone who was selling it new, but they go for around 25-30$.
It allows you to use DEX mode and it has all the necessary ports -> HDMI output, DC input, several USBs, some even have ethernet ports and SD card ports, but I don't care about them.

Hi there,
Yes, it has a charging port and it works.
Cheers!

This thread is pretty old, but I'm finally looking at upgrading and have some questions about the Ugreen UCB C / USB 3.1 + HDMI Adaptor.
I'm looking at the USB C - 5 Port Adaptor here:
https://www.amazon.com/UGREEN-Adapter-MacBook-Matebook-Chromebook/dp/B077FZQS95
In the notes it says that
USB C PD fast charging is only for laptops but not for phones. Phones only support normal charging.
Do NOT recommend you charge phone through USB 3.0 port as USB port only can only offer max 1.5A current and will charge your phone slowly
So I'm trying to figure out, is this like a powered USB hub that needs a PD brick to power the hub and then the hub powers the tabled (with 1.5A max), and separately powers the HDMI adaptor, UCB 3.1 devices etc., or is this a power-pass through that powers the tablet (slow) and then the tablet powers the USB devices?
In other words, is there an advantage to buying a $20-30 PD wall brick to power this hub, which the tablet doesn't support, or am I as good as I'm going to get with the original Samsung Lightning charger that came with the tablet?
Thanks,
Joe

Another possibility ...

* charging OK
* DeX OK, you can use mouse + keyboard, or phone as trackpad
* HDMI video / audio out OK (or you can choose audio out via phone jack, sounds better)
* card reader
* NEEDS POWER SUPPLY!

So this is interesting in that the British version has a warning:
Please read carefully before use:
Use the original AC adapter of your device to charge your device via the USB-C Power Delivery Port on this hub
The Tab S4 (my device) original charger is NOT a 100W PD charter it is a Samsung Lightning Charger not quite QC 2.0.
Again, it isn't clear to me whether these PD powered hubs are acting as pass through for the power to the tablet/phone, and then the tablet powers the peripherals that are plugged in, or if it is a powered hub, that independently powers the peripherals and the tablet/phone - and is smart enough to power the tablet/phone with QC 2.0.
The UGREEN adaptor implies that PD is downconverted to QC 2.0, but doesn't say anything about the peripherals. This FLYLAND hub says not to use a PD charger at all.
This is So much more complicated than it should be!

I am using Tp-Links usb 3 hub, it works great. It uses external power source and its not draining too much power. Ugreen has only 10cm long cable. So pros and cons.
---------- Post added at 07:42 PM ---------- Previous post was at 07:41 PM ----------
Ugreen has good solutions also

I have used a number of different USB Type-C docking station with my Note 8 N950N and they all work with Dex Mode. It even worked using a official Lenovo ThinkPad Type-C dock station.

This update continues:
I've been using Hub Ugreen CM511 for 3 months. I connect (in addition to my laptop) monitor, speakers, mouse and keyboard, sometimes a flash drive. I'm satisfied, each input works, file transfer without lag and it doesn't heat up. Any questions?

Is there an OTG cable that works with Samsung?

I have an SM T290 tab A. Is there a specific OTG cable that I can use? Has anyone had any success?

I know it gets to where you're pulling your hair out in frustration, but.... someone on XDA has nudged me in a new direction and helped, always friendly, and ALWAYS FREE. I had the same problem with cables, I thought anyway. I'm enclosing a pic of the OTG adapter that worked for me, and with every cable and thumb drive, etc. It says SAMSUNG, its just hard to read. Hope this helps Scampo.

can you attach a thumb drive to your tablet and watch a movie on it while charging at the same time?

What I did instead was to connect a small powered USB hub and connected my thumb drive to the hub. That way you reduce the power draw on your tablet and can run a wireless USB mouse with your thumb drive. (And yes, I watched movies that way). Hope it helps.

Here is the cheapo I've been using bought off eBay for like $1.50

Thank you but I need to charge while the thumb drive is attached and I need to be able to do this 24 hours a day 7 days a week.

On amazon you can get an adapter which gives you 3 X usb 2.0 (thumb drive) input plus one usb-a micro (usb 2 charger) input. Mine has a switch between OTG and charge, but if I keep charger in during OTG, it supplies power to thumb drives, and the battery supply barely gets touched.

This is an automotive install and I've tried all of these options and none work. These tablets and fiberglassed into the dash and need to be charging all day. Then a female USB mounted in the dash to transfer data via a thumb drive.

You'd think that anything installed into the dash like that would run on the car battery. I just use mine for development, which means nothing more than saving / loading text files. I am able to leave it on charge and just flip the switch for 30 seconds or so at a time to access the thumb drive. What about the usb to sd card readers? Same result, I suppose?

Yes, same result. This was a headache when I started this 10 years ago with the Nexus 7. But someone came out with a specific automotive installation where the tablet would turn on and of with the key and it would charge with a thumb drive attached and it worked beautiful until it fell out of service.

After a year of working on this problem I found a charger made by a company called lava. The charger is about $100 and it does charging while having usb support. The charger is worth more than the tablet but I didn't have a choice.

I know it’s been a bit since this post, but curious if the lavalabs adapter you mentioned worked with your sm t290 ? And if so, which adapter model was it? Trying to figure out the same thing, they are pricey but need to figure this out thanks ++
