What's the differences between OTG cable and the one that comes with the Nexus 7?

An OTG cable is not for charging/connecting your device to a computer. Instead of usb micro to a male usb, it's micro to female usb, so you can plug in peripherals and flash drives etc. to your device.

When a normal USB is plugged in, the Nexus is in "slave" mode. Receives instructions.
When an OTG cable is plugged it allows it to be in "master" mode. Can give instructions.

Stop... MUFFIN TIME!!!

There are basically 3 types of cables you can plug into the USB port of a Nexus 7:
1. A normal USB-to-microUSB cable, plugged into a computer or a USB charger. Either way it charges, and if it is hooked to a computer the N7 is in Client Mode and you can transfer files as well.
2. High-current chargers (like the one that comes with the Nexus 7). The data lines on these are shorted together; this tells the Nexus to accept higher current on the power lines for faster charging.
3. OTG cables have the normal 4 wires on the USB end - two for power, two for data - but on the microUSB end there is a fifth connection called USBID. Normally (as when using a normal 4-wire USB cable) the USBID pin is floating, i.e. not hooked to anything. On an OTG cable, the USBID pin is connected to the ground wire. This tells the N7 that an OTG device is plugged in, which causes it to do two things: it reverses the current on the power lines - because it needs to power whatever you have plugged into the OTG cable, like a USB card reader or keyboard - and it switches the USB interface from Client Mode (which it uses when it is plugged into a computer, because in that instance the N7 is a peripheral device) to Host Mode (because in that instance the OTG device is the peripheral and the N7 is the 'computer').
There is one other option for charging: the pogo pins on the side. (The 4 pins are 5V, stereo left, stereo right, and ground.) Providing power to the pogo pins (as when it is put in a dock) tells the N7 to accept high current on the pogo pins. Momentarily connecting 5V to the right stereo channel tells the N7 that external speakers are connected and it starts driving audio out the two center pogo pins. When this is happening the charging takes place through the dock, the USB connector can be used with a data cable or an OTG device, but no charging takes place through USB when the dock is connected. (An OTG device is still powered by the N7, but current never goes the other way.)

Dont forget a "y cable", which can charge and preform host mode (otg) at the same time, only at a slower charging rate. This is providing you are using a kernel that supports this function. "Otg+host mode charging"

[Q] Will This Adapter Work With a USB Flash Drive?

This is a Male Micro-USB to Female USB 2.0 adapter
Product Link
I want to exceed the 4GB file size limit and would like to not have a wire dangling off my Nexus 7 or Nexus 10 while I watch a movie.
It doesn't state that its USB OTG, but a review said it worked on his Motorola Xoom.
Please let me know what you guys think

it does look like the same as a USB OTG cable, only a direct adapter.
Take a gamble... it's cheap enough...
What is the worst that could happen other than it not working?

The advantage of "a bit of wire" is that you only have a micro USB plug and wire hanging off the USB socket as opposed to a rigid USB micro + USB F + USB M hanging off the USB socket. Which configuration puts less strain on the USB socket if it's knocked, twisted etc.?

[Q] USB3 cable from ebay

Hey, i just received my usb 3 cable (my s5 came with usb2...) and i think i got a fake one...
I bought it from here: ebay.com/itm/291161252997?var=590311054317&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Now the problem is, when i plug cable in it USB options there is no "Media device (USB 3.0)" option... Which if i am not mistaken should appear?
I don't understand... 190 cables sold and no one is complaining... Maybe i am doing something wrong?

You might connect it to a USB 3.0 Port, are you sure that you connected it in 3.0 port?

Yes i am sure i connected to usb 3.0 port. I just found out that my external monitor connected via usb using same type cable as i ordered (but it's very short cable) and it is usb 3.0. Tried connecting with it and now i can see that option. So i guess that means i got fake cable...

Based from my experience, buying micro USB charging/data cable for Samsung is tricky since the wiring may not be the same as the normal USB cable. There should be 5 pins on the micro end, but sometimes there are just 4. But Samsung uses only 4 pins that might have been rewired. I'm not sure whether only Samsung does this or the same can be said of the other brands, but they may be the cause why there are microusb cables being sold that does only charging and no data function, and vice versa. And sometimes the pins may not be protruding out enough to make contact with the phone's charging pins.
I hope this helps.

You should try plugging in another USB 3.0 device such as a USB stick to determine whether the fault lies within your computer or the eBay cable!

USB to C cable

Any good recs for a USB to USB C cable that is longer than 1 foot? At work I'm constantly plugged into my lap top but this short ass cable isn't cutting it.

I've got this cable on order from Amazon. However the delivery date is pretty long, so I haven't been able to test it yet...

Thanks.
Everytime I've bought a cable from Amazon it always ends up crapping out after about a month. What I mean by that is the end that plugs into the phone "loosens up" and doesn't really stay in the port.
The type-C port seems to be a bit better, but we'll see after some time.

If you check Google+ for Benson Leung he is recommending a couple of cables on Amazon. (Sorry, I'm new to this forum, so I can't post links yet.)

Assume you are asking for a USB Type A (male) to Type C (Male) cable based on plugging into your laptop? Or are you looking for a USB Type C (male) to Type C (male)?
If the former, there are tons a decent cables ranging from 6" to 6.6ft on amazon. I have used the Cable Matters ones and the iOrange-E ones.

Nexus 6P, Android Auto, faster charging question?

So, my 2014 Kia Soul has a new map update that is arriving in the mail tonight, and it includes Android Auto. I know I have to connect my device directly to the USB plug in my car to use it, but I have some questions for everyone.
I want to be able to keep my phone QUICK charging at 3A but also connect for the USB requirements for Android Auto. I also have a 32gb micro sized USB drive I'd like to keep plugged in, as it is loaded up with great driving music. I can live without the USB drive if needed, but really want to keep the ability to quick charge.
If I use an adapter like this one.
https://www.amazon.com/gp/product/B01A6ZPHAQ/
And connect the Type C connector on that to my phone, and then the Type C USB charger in my car to this, can I connect a Type A male to Type A male cable to satisfy Android Auto?
I hope this makes sense. I'm thinking it'll work, but maybe someone else has tried it. I have this adapter from some testing I did, but don't have a male to male type A USB cable to test out with yet.

I am almost sure it won't work. And where will you get 3A power to quickcharge? Cars usb are not prepared for that.

I would get to 3 amp power from where I get it now, the quick charger that I put in my car as mentioned above.
So the USB C cable would go from my current charger to the USB C in port on this adapter, which is designed only for charging through that port, then a USB A to USB A cable to connect the car USB port to the USB A port on the adapter.
I picked up a short USB a male to male cable earlier today so I can test this on Friday.
