Cable OTG

Hello guys, I'm interested in one thing...it is possible connection of external memory (Pendrive) using a cable ? (photo below)
Is any software to operate this ?

I don't think it would be possible as the memory in the pen drive needs voltage for it to work, can't remember if it's 3.3 or 5 volts but I doubt galaxy could power it or read from it.

but in nokia n8 this is possible and this phone has the same cable as the picture.
I'm thinking that is needed a suitable program to control this USB...

Nokia has a powered USB port which supplies the connected device with sufficent current in order to read/write to it.
I don't think the Galaxy has ability to output power through it's USB port so with just software I doubt you could achieve it. You would likely need suitable software and also an external power of some sort like a USB hub.
Some people have been trying to achieve this on the Nexus One, but also requires an external powered hub:

I have the Toshiba 1TB external that connects with other tabs (no external power). The Note 10.1 "tries" but fails. Perhaps a power issue as this drive has connected with android tabs in the past.

I'vegot an old Buffalo DriveStation 1TB drive. It's an externally powered 3.5" disk with a USB 2 interface. Just tried it and it works really well. Films stream very smoothly and theres no delay in accessing files.

I possibly have the same drive. The only way I can use it is to use a usb 'Y' cable which has 2 usb plugs and 1 usb socket, you plug the hard drive into the socket, one plug goes to the tab and the other one goes to an external usb power supply i.e., laptop or usb mains power adapter. If you can't find one they're easy enough to make, just google it.
From what I understand, our Tabs don't supply enough power to run high power devices such as most usb hard drives.

[Q] P6800 7.7 NO USB audio PLEASE HELP !!!

Hi.I'm new in Android world.
I work on my car stereo project and it's in the middle and I stock with usb-audio out issue.
I have a Samsung tab 10.1 from local AT&T store and P6800 7.7(int.ver.) that I just bought to use as a head-unit in car.
When I connect 10.1 tab to DAC the power lights comes on, on DAC and HUB and it gives me audio out of USB (30pin) .
When I connect P6800 to DAC the power lights comes on, on DAC and HUB but i'm getting message warning "high power USB device connected... cannot access this device." and sound goes to internal speaker.but USB-HUB powered by external power supply.
Restarting with connected or disconnected HUB makes no difference,same result no sound via USB.
The 10.1 already came with ICS4.0.3 and 7.7 I updated via Kies to ICS4.0.4 and both support USB-Host.
I'm using 30pin -->USB-HUB OTG kit --> Behringer U-CONTROL UCA202 DAC.
Question is WTF is wrong?
Should I flash 7.7 to ICS4.1 or any other custom ROM?
Anyone ???
Thanks

Can u charge 10.1 with pc? In settings, go to dock option and check it, you must use the original dock, 3rd party accessories are no guarantee to work. Try flash custom roms but i doubt they will also cause ppl hardly succede with hdmi let alone dock sound, plus atm they still have problem with stable roms :|

Thanks for reply.
Yes it can charge from PC, even if it's says "Discharging" it's actually charging but slow.
Also I just tried to connect already powered HUB to 7.7 and it's doesn't give me warning about " Hi-power usb connected but can't access " anymore,
it looks like exact like it would 10.1 connected with green lights on DAC and HUB but sound plays internally no mater if dock opt. checked or unchecked .
I assume 4.0.3 vs 4.0.4 does not related to that issue as well as 3rd party accessories since it's works with 10.1.
Flashing custom ROM and loose some features is doesn't sounds right too.

Well they are 2 different devices, you cant say that. The softwares are different. I noticed you use the word hub. Try connect directly to the tab, and try different accessories. Its hard to compare different devices even though they share similarities. Perhaps compare 2 7.7 is better.
Or youcan send me the tab and i can have a look at it. Mine works perfectly

What accessories do you use to connect your 7.7 to DAC?
I mean HUB or otg cable?
By the way usb flash drives and memory cards works fine with 7.7 via that usb HUB. I'll buy otg cable to see if it get me audio out.
Here is the HUB

Nope this rubbish won't work. Haizz. Wasted time with you when you insist on your mistakes. Hubs won't work ever. From 2.0 speed you get down to 1.1

OK I got this OEM Samsung USB Connection Kit direct to DAC. DAC light is on,"USB connector connected" came up but same result.Only internal plays.

OK I GOT AUDIO OUT with "rubbish" usb-hub mentioning above but only when I use "USB AUDIO RECORDER PRO" app. So it's not hardware issue it's on software level.
How to make it happen with other apps without flashing? I need to make it work with any internet radio apps.

Ok it was purely luck. Otg are purely for connecting external devices to your tabs. It is not meant for connect your tabs to other devices. When you connect it to the PC you can see that it require driver for Samsung for the PC to recognize it. This tag does not have mass storage mode, it only has mtp and ptp mode. So the proper way for it to function as media storage is to connect it to the PC, or having a media player can function as the PC would, but I doubt there is such available. Maybe you cab try Ubuntu embedded? Again I don't recommend such measure. It is getting too complicated.
Or you can also build a media player with driver speicifically working with this tabs to specifically pick out the audio output from the USB
Or you can use the original dock and connect the audio route. It is much simpler
Or you can switch to apple devices, they are popular and get supported well.
And you can send the tab to me
Sorry buddy, you ran out of luck

"build a media player with driver" OR "use the original dock" are not the options, and apple is not even under consideration.
Actually I do use original dock ,but it does not provide the options to get data of USB, it's for charging purposes only.
So I just removed that 30-pin connector and used one from USB-hub.
The only question is to find player that capable to send sound to USB.
ANYONE PLEASE?

God with this Guy. With the dock not only you get sound output but also HDMI. go snd buy the original one
Sent from my GT-P6800 using xda app-developers app

The original vehicle mounting dock has sliding 30pin to round connector adapter only and cable with usb to that connector is included.
so what hdmi you talking about? Unless you talking about different dock but I'm talking about this to be able to use it in car

No the stand dock on table, the car holder are just for holding and charging, if you want you can stick the desktop dock on car surface, or connect the car dock to the stand dock

Yes I can but it does not give me USB-audio out anyway.
It's a driver issue.I can flash to custom ROM but still did not confirmed what ROM support USB-audio.

Tab 2 OTG+Chargeing

I have been working on this project for a while. I am putting a 10.1 galaxy tab 2 in the dash of my truck.
I am using an xternal sound card via an OTG cable and a powered USB hub.
My only issue is now I need a way to charge the tablet also. It is getting power via the powered USB Hub, but is not accepting the power because the "vbus is set to output not input"?
Any one know how to make this work?
I am a complete noob, I appreciate all your time and help.

You need to modify the USB cable, this way (I dunno if it works, since I don't own an OTG-compatible device).

Thats for a mini usb no?
I have a 30 pin.

Just found this. Doesnt have my Tab 2 10.1 listed. but it has the 7" and note 10", which I believe they all have the same connector.

Gonna call them tomorrow and ask.

[Q] Portable Hard Drive OTG Power Needed?

Hi guys
I was just wondering if i will need extra power if I want to connect my nexus 5 to a portable hard drive via OTG? If there are any that don't need extra power, what are they? I'm in the UK thanks.
/A-B

A portable hard drive will need external power. Don't know any that don't. The power draw is too high for the device to handle it.

I have a 250GB Western Digital Passport, 1TB Samsung M3 and a 500GB DIY portable HDD I made with an old laptop drive and USB 3.0 enclosure from eBay... and none of them require an external power supply as they're all USB powered.
Also, when I had a Note 2 I could connect these drives to it... so whilst I can't say for sure they will work with the N5, I don't think it should be ruled out.
I'm at work right now and have no idea where my USB OTG cable is, but if I can find it when I get home I'll test them out.

Since the S3, all flagship Samsung have been able to power OTG Mechanical HDD's.
On the N5, many will not power however recently a few people have said they have managed to do so, but whatever. Generally the advice with the N5 is you need a powered USB hub. Some may work without but we dont have a catalogue of what works.

I'd really appreciate that CitizenLee. The Samsung M3 was the portable hard drive I was thinking of buying and I would be great to know first hand.
