Hello,
I have the TF300T (without the keyboard dock), and I want to get a USB port dongle. However I have two needs:
I want the USB port to provide enough power for a USB 2.5" hard disk. I suppose I can use a powered USB hub for this?
I would really like to be able charge the tablet when the USB dongle is on. Is this possible?
Thank you

If that USB HDD requires 2 USB (one data one power), then a powered hub is your best bet.
When the USB dongle is in, it takes the place of the charging port. You can either charge the tablet or use the dongle.

hi, i am planning on buying a micro usb to usb female cord and i wanted to plug the micro usb into the xoom, and a mouse into the usb female. would that mouse work with the xoom, or will the drivers for the mouse not work? thank you
I'm not sure, I don't use a mouse on my Xoom. But I have heard from other Xoom users that the Bluetooth Mouse works.

If you want to use a USB connected mouse you need the Xoom to be in USB host mode. You need to have flashed a rom or kernel that supports USB host mode and you need a USB OTG cable, such as the Motorola Camera Connection cable. You can't just use a regular USB cable with a micro end and a female end.
but you can build your own OTG cable.
buy a micro usb B head
and a usb A recept
and solder it together
the schematic is quite the same like the factory cable
instead of soldering pin 1 to 5 (+) like the factory cable u have to solder pin 4 and 5 together (ground)
you can find a lot of DIY tut´s just google it

I can provide OTG HDMI converter Factory cable. If you need, you can PM me.
Just bought this cable from Amazon
It works just fine with wireless Microsoft Keyboard+Mouse but was not able to make it work with my Lumix Camera and Card Reader. Seems there are problems with Android version 4.0.4
My Xoom is MZ604 WIFI only NOT Rooted. Keyboard and Mouse works fine even without rooting it.

I think it's the XOOM do not support your camera module(no this module driver).Maybe you can upgrade OS to FIX.This issue is ONLY driver issue.
Hi I can't find a definitive answer but I think it is no. Anyway does anyone know if it possible to do the following?
Get TV out (HDMI) + usb host working at same time
Get usb host (hub or not) + charging the tablet
Get hdmi out + usb host + charging.
I think our tab works with the media dock for the 7" tab but can usb host be added as well? The dock for the note 2 looks amazing and should really be available for all devices like this.
Cheers

I don't know the technical terms behind this but here's the gist of why this won't work: When you are using the HDMI out or the USB OTG it puts the multi purpose connector into a proprietary mode which will I/O a protocol that works with that particular type of device. So when it is in HDMI mode it is using certain data pins to connect with the HDMI pins, and when it is in USB OTG mode it is using some of the same pins to connect to USB data pins.
It can only be in one mode or the other at once, so if you hooked up a hub to a usb OTG connector, or used a USB OTG hub, the jack on the note is going to be in USB OTG mode/protocol, and it will not recognize an HDMI adapter also connected to the hub as an HDMI device that it supports. Only storage devices, HID input devices, and samsung printers are supported on the USB OTG.
Since this is a hardware restriction, I'm 99% sure it cannot be programmed around. I think the same applies to why you cannot charge while using the USB OTG. As far as I know all the HDMI adapters require a usb power source and will somewhat charge the tablet.

Thanks for the info just what I was after, it all sounds like a bummer but not too bad. Sounds like I will need root to connect a ps3 controller then.

No need to root for ps3 controller use. My sixaxis works fine using the standard usb adapter. You'll only need to root if you want bluetooth connectivity.
Hello, we all know that there are USB OTG Cables with extra power plug (Y cable) but those are supposed to power external device like HDD, DVD, or anything what consumes more power than our android device can handle.
But my question is: is there any USB OTG cable with additional power plug but for simultaneous tablet / phone charging while USB stick is used?
I want to watch something long (i.e. TV Show series) from USB stick via OTG cable but I cannot simultaneously charge my tablet, so if it take too long my tablet will be out of power before I stop watching.

That means I have to add a resistor only to usb connector or just need a different kernel, or both?
On the native firmware say that this support function is disabled. Personally, I use this CivZ-FLEX-ЛУЧ-REV3.6.2 + SphereXtreme, where works flawlessly with OTG + charging resistor 64.9 K.
I call BS!!!!
I have a stock firmware, and have been using all kinds of USB cables. Found the best are made from Sony/Ericson and Blackberry. Once you have a quality cable your charging issues will go away.
Right now I am using a 7 foot cable that is from a Sony. No charging issues and works perfectly.
Lately I found another MHL cable 2hich is called HDMI to Micro HDMI, and that micro HDMI plug looks exactly like micro USB. Will such cable work with Note 8 properly without additional power?
The version of MHL our device supports requires a power source external to the tablet. That means the adapter itself needs to provide the power (battery or power adapter) or can pull enough off the HDMI cable, which is usually not enough juice to run the connection.
MicroHDMI and MicroUSB are also not physically compatible (won't fit the same port and different pin outs) even if they look so much a like. MHL typically uses MicroUSB at one end and full sized HDMI at the other.

This is correct u need to put a 63-65 k resistor between ground and Id pin(pin 4 &5) on USB connector. Doesn't work on civatos 4.4.2 as of now. USB host works fine with regular USB host cable but no charging when u use a y cable. I use civatos 4.2.2 kernel also. Works on yyks note 2 4.3 port also..
I have test multiple times. I use a USB dac in car and need charging and USB host.
what resistor should i use on my sghi257m samsung galaxy s4 mini otg usb cable?
on my dads galaxy s5 Active it shows message that says: Do you wanna enable power sharing
is that OTG? on my S4mini nothing pops up
I know this thread is really old but i want to use a USB DAC so need at cable with a resistor as mentioned above but What ROM should I use now?? also is there anywhere I can buy a cable with resistor in it or do i have to do it myself?
Considering to use a Huawei Mediapad X2 7.0 for my 2DIN car install, since the dimensions of the tablet are nearly identical to 2DIN,
Therefore I would like to know if the device supports USB OTG Host mode and charging the battery of the mediapad simultaneously using a certain Y cable?
Thanks, much appreciated if you can give it a try!

Not sure about OTG Host cum charging combination because my understanding if you use OTG Host mode very likely you plug in a USB OTG thumb drive meaning you cannot charge at the same time.
However connecting the X2 micro USB port via standard USB cable to my laptop, I noticed I could use it as an USB device and it charges at the same time albeit not as as fast as a dedicated charging.

Yes, but not OTG.
I can confirm that, on my side, using an OTG hub with a external power plug, no way to have the device charged by external power when in OTG mode.
It is OTG or Normal charge and functions via USB.
Seems Logical because the Phone is supposed to provide the power to its USB accessories in OTG. Just my HUB has a switch that provide power to those accessories instead of the phone Itself. May-I add that switching this power button on the HUB does not function until you had unplugged & replugged the Hub in the phone after switching between the two modes. I'm afraid of the survival of the Micro USB plug of my phone, on the long run, with all those plugin, unplugin actions !!!
It's possible but with anothere Device the Nexus 7 (2012/2013) with Timurs Kernel. What's the difference of this kernel to the normal kernel, so OTG with charging is working for this device,too.
Hi guys, a friend of mine have and old Samsung android based phone.
I was thinking about give it a better use as an android tv box/media player, but I have a few questions, main concerning USB OTG.
I could use a USB OTG Y cable, so I could charge the phone while using it, and still have the OTG... could I connect an USB hub to the OTG so I could use a USB mini keyboard and a mouse?.
My other problem is the micro usb port and the HDMI conection to the TV. I could use a cable to connect the phone to the TV but then I couldn't connect the USB OTG. It's possible to connect HDMI and still use USB OTG???

Well... just so you know you can't have the phone charging and in OTG mode in the same time. Not even with adapters. This is because the current in USB can't flow in both directions in the same time (because there aren't enough dedicated wires)
