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.?

Hi,
I made my own usb otg adapter from a plain usb a to micro b adapter. You have to connect pin 4 /which is not connected/ to ground to fire up host mode.
Edit: It is not easy to dismantle a usb connector or adapter and it requires soldering. So I guess anybody with the necessary skills will find the pin on his own. I will not post photos because my solution is far from being pretty.
For everybody else: the nokia USB OTG cable is wired the same way so it is very likely that it will work. (on Hungarian forums I saw references that it works, but I can not guaratee it.)
Tommorow I will go buy one and report.
USB Host mode will allow to connect USB pendrive, mouse, keyboard etc. to the SGS II.

this is very useful for people like me who knows how to solder things, but for the people who have absolutly no Idea what you are talking about, you should add more details/pictures to the OP so the people who doesen't know much about electronics know what you are talking about, and what benefits it brings for them.
I myself will probably make one or more, so I don't have to always take my USB OTG with me all the time.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries
As one knows, Samsung has promised a HMI Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !
Instead of shorting pin 4 and 5 from within the cable head, would it also be viable to short them from within the device itself? Say if I disassembled the phone to access the back of the female usb micro connector and soldered the pins. Would there be any damage caused if the permanently shorted pins 4 and 5 (within the device) is connected to a charging adapter/PC?
I have been using a ps2-active usb adapter to run my old clicky keyboard to my A200, but thought that I will be upgrading to a 500 or 510 or 700 shortly so was going to try a micro usb-> female full sized usb cable since the full sized usb port is missing on most current tablets. I bought one on amazon but didn't get any connection and then saw it was a OTG cable after I ordered. I wasn't even sure to check first hand if there is any difference between a micro -> female full usb port cable that is OTG vs. non-OTG... or if I just have a defective cable.
Is their a tiny USB OTG Adapter? I am getting a micro USB flash drive and I have an OTG cable but its long. I would like a wire that can be as small as possible. Is there such a wire?
I have a micro USB adapter attached to an OTG micro USB adapter ..

I had searched Amazon for 'usb otg cable' and there are lots of them. The one I got is 5" long and had a 90 degree microusb connector so the cable is parallel to the bottom of the N7. You can buy one for $1 or less. I also bought a tiny microusb reader and 32 GB microsd card that plug right in and weigh almost nothing.
Micro USB to HDMI for s4
below one is cable only
http://www.amazon.co.uk/HDMI-Adapto...Micro+USB+to+HDMI+1080P+HDTV+Adapter+Cable+s4
below one has power source.
http://www.amazon.co.uk/Samsung-ET-...Micro+USB+to+HDMI+1080P+HDTV+Adapter+Cable+s4
What is the difference? Is the power source for the second one used to power supply the phone to extend video play time?
Thanks.

MHL/HDMI Adaptor for Samsung Galaxy S4 S3 Note 2 - comes with usb cable to plug into power source (generally the TV itself) as well as the HDMI adaptor to plug into the TV.
Samsung ET-H10FAUWESTA Micro USB to HDMI 1080P HDTV Adapter Cable for Samsung Galaxy S3/S4 and Note 2- White - doesn't supply the usb cable to connect to the TV BUT still needs it. It uses a micro USB to USB cable - the same that you use to connect to a PC or your charger... You also needa HDMI cable to plug into the box and TV...
Other than that it's just price...
aha, If I understand correctly, the first one is a complete set that usb/hdmi connected to tv and micro usb to phone.
The second one, i will need to have another usb2micro cable.
Dammed it, from the description of the product, seems like the one with more options. Indeed it is not.
Thanks for clarify it.

Its always good to do a little searching on these things, here's a link to the 2nd adaptor again at almost half the price of the one you linked to - http://www.amazon.co.uk/Samsung-Galaxy-S4-HDTV-Adapter/dp/B00BTCPQ5C/ref=pd_sim_sbs_ce_1
And here's your link - http://www.amazon.co.uk/Samsung-ET-...Micro+USB+to+HDMI+1080P+HDTV+Adapter+Cable+s4
Can you spot the difference?
The difference is that the product in my link got no buyer
thanks for the information. Likely I will go for cable solution

Am beginning my project to install a 2012 N7, 32 gig, wifi only, in my 2006 Scion xB double DIN as a replacement for the stock head unit. I am keeping the stock speakers for now. I am adding an external amp.
I've done head unit swaps over the years so I know how to open up the dash, remove the existing unit, and how to wire up a regular head unit.
Here's question #1. I am going to use Timur's kernel (using USB ROM for Nexus 7) so that I can use a USB hub and the OTG cable. The OTG cable micro USB will plug into the N7 micro USB port, but the other end of the OTG cable has two plugs. One is a regular USB (female), which I will need to gender change so I can plug into my powered USB hub. The third plug is a micro USB female. Is that third plug needed to bring power or data back to the N7? And if so, what does it get plugged in to?
To power the hub I plan to use a buck converter connected to a dedicated 12v line. The converter will step the voltage down to 5v 3a to power the USB hub. The only thing coming off the hub will be the N7 and a USB 3.0 thumbdrive that will hold my music library.
The second q concerns heat. I'm in S Texas. Has anyone experimented with leaving the back of the N7 off and adding a heat sink to the battery, or adding some sort of insulation, or diverting AC air from the existing ductwork (for when the car and AC are on)? Just looking for ideas.
Thanks in advance for any and all help.

Timurs kernel is old. Use kangaroo rom or any 4.4.2 rom and kangaroo or oxydo kernel in the kangaroo thread there is a power manager app that will allow the tablet to fast charge and turn on and off with ignition. If your worried about heat buy a 12 volt fan and power it up with 12 volt from car. The micro usb female is for power use the cable that came with the n7 Power it with a 2amp or more 5v power car charger(i bought a samsung branded) works great. You dont need a hub if your only gonna power a flash drive. Micro male to tablet, full size female to flash drive ,micro female to nexus charging cable to usb car charger plug.
The GPS WiFi Bluetooth and NFC antennas are all on the back cover so none of them will work without it. So that means no sat nav or internet. I wouldn't worry about cooling it the tablet is meant to function with the back on in a variety of conditions. If you want you could cut a hole in the back there is a copper sheet that is the Nexus's heat sync. Maybe hook up a CPU or graphics card heat sync out a desktop. Or even just stick it to the plastic back its bound to do something.
