[Q] Help with otg cable - Galaxy Tab 2 Q&A, Help & Troubleshooting

Sorry, i am new to this site but I wanted to know if I can use my standard USB charger, short out certain pins to be able to go into otg mode, I made my own female to male cable so I'm happy, but I was wanting to know if it was possible.

No. OTG uses different pins

You most definitely can, but you have to mod the 30-pin connector itself -- it can't be done on the other end of a USB cable. You will find all the info you need here:

[Q] Male Micro/Mini USB to Female Regular sized USB

Does anyone know if I purchased one of these can the Transformer then read memory cards or use other USB peripherals?
no one has tried yet, try it for us and find out!
I would if I had the tablet. If it does it would be a major plus.
Well we know for a fact that the 40 pin connector that is used to hook up the tablet to PC and charger through USB allows for USB host, we just don't know if it would be so simple that all we have to do is use a female to female converter.
I would think that it would work, because that's how you transfer files to the tablet. Not sure about peripherals though. If this does work it would easily make this better then any tablet.
if I can get myself to put down the money and if someone posts a link I'll try it.

I meant usb female to USB female since I don't have anything with microUSB just wanna test host.
Just bought http://www.amazon.com/gp/product/B000BSN4UY female to female adapter, I'll test USB host I guess
The tablet only has a micro, so I guess I don't understand why you would buy that item.

The tablet doesn't have a micro port, it has a proprietary 40 pin to USB male cable with a proprietary 40 pin socket. So you need atleast reg female to reg female to get host at the minimum.
Never mind just figured it out. You are going to use the micro usb cable that can with the tablet and hook up the female to female. Sorry.
I thought the tablet did have a micro usb host?
only ports are the proprietary connector used for hooking it up to the PC/charger/dock and mini HDMI out. But the proprietary connector supports USB host.

[Q] Asus Proprietary plug to USB converter? or anthing similar out there?

I was wondering if there is any such device / cord which would convert the Asus proprietary plug on the transformer to a USB cord or something so I could plug in different things without having to buy the keyboard....
Yes it does exist:http://www.asus.com/Peripherals_Accessories/Eee_Pad_Accessories/External_USB_Adapter/
Could you charge the tablet with a regular USB cable using that adapter?
Only when in deep sleep or turned off - but it charges.

No because the USB adapter linked only outputs 5v on the USB port, its not an input.
The USB socket is the wrong type for normal USB cables used for charging, but even a USB-A to USB-A adapter wont allow charging and may even destroy the USB adapter (well, it might not, but I certanly wouldnt want to try it!)
That is sort of what i was afraid of. I was hoping that since I can use the propietary cable, I would be able to switch to a longer cable with the help of the adapter.

Just attach an usb3.0 cable to the propietary cable. Then you have a longer cable.
I'am using this with the tablet and charger.
It has to be USB 3.0 cable? Dang, I actually do have an older extension cable somewhere (forgot all about it until I read your post) but it is pre-3.0, but hey, if i find it I will at least give it a try, not like something would brake, right? Right??
hmm...I had asked this in my thread, but no one has given me a straight answer. Looks like it wouldn't work even with Male A to Male A. I already bought one, so maybe I'll give it a try. Has anyone done so before?

Yes, it must be a usb 3.0 cable.
I have this one and can charge the tablet with this cable attached to the propietary cable and the asus charger
Just tried it again and it is now charging.
That is cool, but I was hoping it would be in a "cord" form because imagine you would have that sticking out from your device, then on top of that you would have your usb plug sticking out as well...
Also, would this work with something like a wireless keyboard and mouse? (the wireless receiver is USB)...

[Q] Asus USB adapter alternative?

hey everyone, so i have been reading around and there are alot of people talking about the usb extention for the asus transformer.
Here is my thought: what if you used your existing usb charger/data cable and then but a female to female usb adapter on it? this has just been in my mind for a while and i saw that the adapter would cost around 3 instead of 20 for the asus branded one.
has anyone tried this or should i just get the adapter made by asus?
For $3 why not just try it and let us know?
I'm pretty sure this will not work, since the adapter has additional circuits to put the tf in usb otg (on the go) mode, which is the usb host functionality in plain english.
Yo will need an usb 3.0 cable. It won't work with a normal (2.0) one
As alluded to above, 2 different things.
The usb3 cable is an extension, the adapter is a hub (adding usb to the tab).

Split cable for charging and OTG

I am trying to charge my Nexus 6P while simultaneously casting a streaming video from a USB drive to a Chromecast using a USB keyboard and mouse (Basically a computer replacement scenario). I have purchased the Cynergy 3 Port Ethernet Hub USB C with USB C connector and everything works independently but I can not seem to get it to simultaneously charge and read the USB port data. When the hub is inserted into the Nexus 6P the phone asks me to choose between 5 USB scenarios (see attached picture). When I pick “Charging” the USB ports stop working and when I unplug the power supply and then plug it back in the phone defaults to “Power supply” and the phone does not charge but the USB ports work along with the items connected to them. So I wonder if simultaneous charging and data is possible with the USB C connector on the Nexus 6P? I have read elsewhere in this forum that it may not be allowed in the USB standard but can’t find any confirmation of this. Has anyone found a cable/hub that can do this or is this not possible due to the USB C connector limitation?
You might want to try something like this.

Why tell him to waste money on something that isn't going to work? The 6P doesn't support USB PD so this isn't possible.
i think you need to do some mad hacks in the kernel to get otg and charging at once (i think they did it on the oneplus 1 and possibly on the 2nd gen n7 so maybe google those for what it needs to be done?) i tried various resistors to the sense pin on the micro usb z4 which ended up not working but i have no idea how the usb c is wired up. Good luck with it anyway

Is there a way to turn usb-c to usb-c phone charger cord into an otg cable?

Anyone tried it? I searched anywhere, but no results

Just try it and see if it works. Some devices could work while others would need a dedicated OTG cable
Thx fydtyh. I will update later

It depends on whether the phone is used as client or as host. If the phone is to be used as a client, normal USB cable is used. If the phone is to be used as host, a OTG cable is used. It is a matter of pinout order.

You can convert the USB C cable into a OTG cable by changing the pinout order as indicated in the following discussion. You will need an adapter to convert one USB C end into USB A.
How different is a normal usb cable from OTG usb cable?
Answer (1 of 8): Hey, So USB OTG cable is used to connect to a device (say your phone, tablet) when you want to use that device (say your phone tablet) as a host. So imagine you want to use a mouse with your android tablet, then you can use the OTG cable as shown in the figure below Major dif...

I know the diagrams show microUSB instead of USB C but the pinout order should still be the same for microUSB and USB C.
