Tab 2 OTG+Chargeing - Android General

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.

How to get this working....

Not sure if this should be here or in accessories thread but....
I have the samsung usb/sd card adapters
http://www.amazon.co.uk/gp/aw/d/B0051D3KMG/ref=mp_s_a_1?qid=1355938585&sr=8-1&pi=SL75
and also a Western Digital external usb harddrive
www.amazon.co.uk/gp/aw/d/B004445JHC/ref=mp_s_a_1?qid=1355938748&sr=8-6&pi=SL75
I cant get the harddrive to connect to my Note 10.1... keeps saying something about high power device???
Now is there a way to get this working??? On my old tablet (original Sony Tablet S) I could just connect the harddrive via an adaptor and it was visible and usable!!!
written with a s pen on my Galaxy Note 2 via XDA PREMIUM APP
Only way would be to modify the USB cable so the drive is powered by another power source I would say.
I'm not sure that will work either. I tried a modified Y cable that has separate power and the HDD is still not recognised on JB on my One-X.

[Q] Is it mandatory to connect the charger with the HDTV Adapter ?

Hi Guys,
I've got my HDTV Adapter for a stock Galaxy Note 10.1, I'm a bit disappointed because it looks like it's mandatory to connect the charger (the cable already has got an extra slot for connecting the charger) in order to make the note send what it is displayed on its screen to the cable so I can see it on the computer screen for example.
Does anybody have an idea if this is true or not ? I'd love the idea if it is an option but not an obligation !!!!

My experience is yes, power is required. But this can be as easy as plugging in the usb to the tv or monitor if it has a usb port, you dont HAVE to use the charger
Which adaptor did you use?

Well, let me tell you why I'm a bit disappointed, I used to have an iPad which used in a lot of meetings moving here in and there with my pad and cable, now I've to have a power source around or even a computer, with a at least two cables with/without a charger, I'm not bothered with that at home but while one business this note didnn't prove to be a stand-alone, I'm not sure if an app that may simulate charging can deceicve tthe note on that aspect or not but so far, this can be considered a draw-back

[Q] usb otg cable doesn`t work

I had my 7.7 for some time and about 2 days ago i've bought a cheap chinese usb otg cable from some shoup around here. I thought it would be as simple as pluging it in and connecting some usb stick like i've done with justabout all usb otg stuff i previously owned. But it doesn`t do anything. I`ve tried other usb devices, the tab simply doesn`t power them at all. I`ve also disasembled the cable and measure it, everything is fine. I`m on stock ics 4.04, also tried a couple of kernels, it just doesn`t work.
Has anyone encountered such a problem.? Damn weird....

errrr....I think I misread your issue and specific item...
sorry!
Still great though!
The usb otg cable is just a plain simple usb cable with a 20kilo ohm resistor placed between 2 pins on the galaxy tab 30pin connector. That's about all the things inside the actual cable. When you plug it in, the tablet should figure out that the 20k resistor made contact with the pins and an accesory was connected. Mine doesn't. The cable is fine, i think there's something wrong with the tablet. Doesn't it supossed to power on whatever you insert on that usb port? Because i can't get those 5v on the port.
I don't know if it's a software or hardware problem....

what file system is your USB Stick using? try formatting the stick to FAT32 and see if its a file system issue
have you tried using another OTG cable? I'm also using a china knock off bought for 4 bucks, running stock ICS and it detects most of the thumb drives I attached to it
thanks for the replies but the situation is kind of different in my case.
In order for the tablet to read what kind of filesystem you have on a usb mass storage device (stick, hdd, whatever) it must first power it on and then attempt to access it. In my case, it simply doesn't power on. So, it doesn't matter what kind of file format it has. Also, if i plug a mouse/keyboard, it won't work either.
I thought that maybe it's a broken wire inside the connector, so i took it apart and measured each pin. The otg adapter is fine, it should do the job. I've also tested on another samsung tab and it worked straight away. It seems there's something wrong with my tab. However, other then this, the 30 pin port on the tab itself seems to be working fine.

How to connect usb 3.0 to galaxy note 10.1

I have a HDD 3.0 and I want to connect it to my galaxy note 10.1, but it isn't successful (usb 2.0 is ok). What must I do?
Hi,
Make sure the drive is formatted to Fat32.
If you are rooted you can use the paragon ntfs app.

It's not successful. My HDD is 1Tb, so it's too big for note 10?

Correct. Note 10.1 does not have the power to handle a hdd, only flash drives.
You could try streaming from the drive to your note over wifi? Although that would only help at home.

Are you asking how to connect the HDD to your Note 10.1 or how to connect it AND get USB 3.0 speeds? I see you say that USB 2.0 is ok, so does that mean you can get it connected?
If you're trying to get a USB 3.0 connection, you won't be able to unless your Note 10.1 USB adapter supports USB 3.0.

Yes, I'm asking how to connect the HDD 3.0 to my Note 10.1. I tried to connect it to Asus Slider, it's ok. Samsung doesn't support for Note 10.1, while Note 10.1's hardware configuration is stronger than Asus Slider

Do you have any other USB hard drives or USB flash drives you can try? It sounds like a problem with your adapter. What kind of adapter are you using to get a USB port on your Note 10.1?

I tried with usb flash and it's ok. Adapter I'm using is origin from chine
Hold up, you have a USB 2 USB flash drive that works or a USB 2 HDD that works?
No-one that's been on here has said they can get a portable HDD working. A message, "High Powered USB Device Has Been Detected" comes up and the HDD doesn't work. It has to be a powered HDD...
So, if you can get a USB 2 HDD working, powered by the Note, we want to know what brand, size and adaptor brand and where you got it...
Otherwise, no you can't use a Portable HDDon the note 10.1 unless it's powered... Forget USB 2 or 3, it just won't work...

Amen to that. My now-departed Toshiba THRiVE 10.1 had that capability and I miss having that feature on my Note.
Not sure you be lucky to get USB 3.0 to work since Note 10.1 has a 2.0 USB.
USB 3.0 is not backward compatible, same with PC that have only USB 2

USB 3.0 IS backward compatible with USB 2.0. I have a USB 3.0 HDD plugged into my PC's USB 2.0 ports right now. I just don't get USB 3.0 transfer speeds.
I'm with the majority on this one. I don't believe that the HDD being used is an externally powered HDD. The Note 10.1 can not power a USB HDD that large.

USB 3.0 is compatible with USB 2.0.
The only problem is HDD power and file system.
get a IDE/SATA to USB 2.0 Cable! or a USB Y cable.
so you can supply extra power to HDD.
also OTG Cable:
APP: Paragon NTFS & HFS+

Thus negating the portability of the note... If I want a Desktop I'll use the one I have already....
Only other option is to use a wifi enabled HDD (like Seagate Goflex satellite Pro in both 500Gb or 1Tb versions now)... Works fine but REALLY eats into your battery life....
Anybody ever tried with an external usb drive with ssd?
Still cheaper than sd cards and more convenient, but don't know if power from the note is sufficient
Sent from my GT-I9300 using xda premium
Bit expensive for something I can use a hell of a lot cheaper usb drive for... Not even sure it would work if the note detects its a HDD..
The problem is not that it's a hdd (a friend of mine has a 250gb drive which works fine when attached to my note, though it's not manufactured anymore), the problem is power. As i assume that an external drive with a ssd draws less power, it *should* work, but before actually buying one, I'd like to be sure

shouldn't this be a kernel problem ?
i also can trick my note to accept my xbox360 controller even while it should give the same message about high performance device.
(first i attach the x360 controller to the otg cabel and then i attach the otg cabel to my note...it works :victory
however i cant get my hdd to works with that method but many other tablets have no problems with high performance devices and thats because there is no restriction in the kernel.
is there a kernel for the note 10.1 that handles this problem ?

with the use of a ssd i wanted to circumvent the use of another kernel, because hopefully the ssd just doesnt need that much power. However i'm not certain about that, hence the question

[Q] Charging Problem

Hello Everybody , I have a Tablet Samsung Galaxy Note 10.1 N8010 . In fact my Tablet is charging slowly and when i connect with the usb cable my computer does not recognize the Tablet . Somebody can help me
Are you using original cable ?
Long cable tend to be slow charing
I just received my Note 10.1, a used one with 3m length cable, and same as you, not recognized by the pc, I ordered shorter one on ebay
Also not sure Galaxy charging works for this tablet, but it's less than 0.5A when using this cable, sooo....
i had a problem like this.
Use the original cable, or a usb 3.0
