Yes an NO lol. All depends what ROM you are using , what kernal is flashed and your device. You could "possibly" run a command via terminal but you wont have the function of both. It will be one or the other.

I would like to mount a USB memory device simultaneously while charging. Are you saying this isn't possible

I think usb otg and charging in the same time is not possible as the two use the 30 pin connector, so you need accessory that is otg and has a socket to connect for charging in the same time, i have not seen this accessory yet
All otg cables i see has a socket only for usb stick and some has additional sockets for sd cards as the 5 in 1 accessory (i have one)

USB OTG cable not working with X :(

I had a USB OTG cable from my SGSII and it worked great but when i plug it into my one X (rogers) nothing happens.
Should something be enabled somewhere? am i missing something? Are there different OTG cables?
It probably must be enabled in a custom kernel. I wouldn't fret..just be patient.

External usb drive and charging

Is it possible to connect an external USB HD and still charge the tab? (Tab 2 10.1)
I am fitting it in the car so will be constantly connected to car charger but also need the HD connected and ideally 1 or 2 spare USB ports (hub)
Can this be done?
Thanks,
Mark

Yes should work with a double side usb cable
Be careful the Tab is drawing high current level by itself , you will need at least a 2amps car charger

Ok, cheers for the reply...
Hard drive will have its own power supply and I'll use official Samsung car charger for tab...

the one I have doesn't charge-- even when using a male-to-male USB cable. But it does work with OTG

Can I use a cheap otg cable, or are the expensive ones better?

Cheap cables are just fine.
Also, it's impossible for the phone to charge while using OTG. For OTG to work some of the pins are used for handling data and therefore cannot be used to charge.
I ordered one from china, took about 3 to 4 weeks, then I ordered from ebay..
they work fine... they only work with jellybean....

Actually, the thing that prevents charging isn't the pins, it is a software toggle that turns the phone's port into a power supply for the external device, the charging circuit is switched off in the pm chip. There are charging/power usb otg host cables available for phones that support it, e.g., Nexus 7, with patched CM10.1, and the phone can get charged while usb hosting.
the 4 pins are still 2 data, two power, in otg mode.
I don't know if a software fix would work for captivate. I've got the datasheet for the cappy power management chip somewhere. if I can find it, I'll report if the chip can support it and if so, then maybe the N7 fix could get ported to cappy.

AW: USB OTG Cable
I use a 0,70€ cable... I don't recommend it, the connection between phone and usbstick interrupts too often.

Yea. It's a bit of a gamble when buying cheap cables. I also bought a really cheap usb otg cable from dealextreme and the connector on the phone's end is too loose. The OTG cable that came with Nokia N8 is ok.
I use this OTG cable: www.amazon.com/Electronics-Micro-USB-OTG-Cable/dp/B005GGBYJ4/. Small US company, offers a lifetime warranty, only takes a couple days to get from Amazon (free two day shipping if you have a Prime membership). I've had a few from them and never had an issue (other than I tend to lose them). Perfect fit and just the right length. Good stuff.
AW: USB OTG Cable
I bought one from Conrad electronics here in Germany, it costs like 6 euros and works perfectly.

I bought a cheap £2.99 cable from Amazon UK which works just fine.
The packet it came in states the brand as 'Afunta' (Made in China).

I wouldn't think it's the firmware. Is this happening when the cables are plugged into a PC or the charger or both? If it's only from the charger, then it could be the charger itself. Hopefully it's not a problem with the female plug on the tablet.
The charger and pc side of it both work fine just not the otg part lol they say turn the tab off and on with the cable inserted but still does nothing and i dont have to do that for the otg cable on my s3...im beginning to think both cables ar dead...i might try splicing them togetherlol 2 cables from 1

LOL, I completely missed the "OTG" part. I've bought a ton of stuff off eBay but I'm always a little leery of what I buy, especially anything electronic. You can get them for $1 + $2.98 shipping on Amazon. I feel a little better buying off Amazon for some reason. In fact, after looking at them, I'm going to go ahead and order one.

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?

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
