[Q] USB Host functionality with stock charger cable + USB female/female adapter

Maybe a noob question, but would that work?
Primarily a usb stick that I would use that way

No, I have not tried it, but they say in this thread that it is not only about power but having a resistor as well:

Tested. Nope, this does not work.
I assume the resister is needed to tell the Tab to send power to the USB.

The resistor is needed to cause the Tab to enter host mode. No resistor - you've got device-to-device and that doesn't work.

Would it be possible to splice the resistors into the female-female usb cable? 2 resistors and a cable is a really cheap way to go.

No, the resistors go between two dock pins that are not connected to the stock USB cable...

old thread, but i am in the need of the same.
would it theoretically possible to have a charging cable with a usb host part spliced in? i need to be able to connect a usb hid device AND keep charging the tablet. Would the current going into the tablet be mucking things up for the usb host operation?

It shouldn't since the charging +5V input is on separate pins from the +5 USB host power. But the Tab looks at the USB D+/- pins to figure out if it should do slow or high current charging. If it sees voltages that make it look like a host is on the other end of the pins, then it does 500mA max charging, and if the pins are floating it charges at max 2A. I don't know if host mode would screw that up. You could look at the kernel source, or just try it and see.

How to make OTG work?

I bought a micro usb to female usb adapter and I've tried using Faux's kernal, Da_G's .42 kernel and Bullet 2.9 but plugging in the adapter with any usb does not seem to work.. is there any app I need or like how do I verify that it works?

Nope it should work right away. What are you trying to connect? Also, it's possible that it's a bad adapter.

YOU NEED AN ACTUAL OTG CABLE, NOT JUST AN ADAPTER.
Yes all caps, this has been stated time and time again, some people have had luck with the i9100 cables , some have not, you need a cable that works with either the t989 or Hercules, but, I have tested one that was made for the Xoom and it worked as well ...

Well I bought it online and I'm assuming it was made for OTG because what else could you possibly use one for? idk maybe there's another use for it but I can't think of one.
I read something online about shorting the 4 pin to 5 or something, could that work?
And I've tried connecting 3 different flash drives

Yes that could work, that is usually what a OTG cable does, but depends on the phone, the regular adapters are used, to use an Mini USB cable/charger on a Micro port , I use them all the time, because I have dozens of older chargers ....

Ok so I ripped open the adapter and the build quality was too good so I had to just rip the heads off lol so now I have a micro usb end with no wires connected and a female usb with no wires on it. Can I take 5 thin wires and connect the appropriate pins on the micro usb end to the corresponding pins on the female one?
If anyone has a guide to do this, it'd be appreciated

Thanks I tried working it for about half an hour but i couldn't get it to work. I'll just have to order one that is specifically for OTG.
Just as a reference for other noobs like me, the wire MUST be otg for it to work

Micro USB charger falling out from port?

I realyl do not want to return my note II since i already rooted it..and custom rom and kernel..

I have the same problem, and there is nothing to do about it unless to send it back

Have you tried other USB cables? I have the same problem with my stock USB cable too and thought there might be something wrong with my phone, but then I tried a different USB cable and it held on well.

This was my experience as well. Try other cables before you swap out your phone! :good:

The same with my cable. I guess they did it on purpose, that whenever your phone is 'tugged' the usb cable will be released instead of your movement being violently restricted by the force of the cable, which may cause you to drop your phone.
Any way, i bought a 3rd party flat USB cable which length exceeds 3 - 4 times the original cable , and it fits tightly in my phone's USB port. So i believe it is cable related.

I have the same problem, I guess it's just the one they sent. Oh well.
I did buy another cable, however I noticed that charging becomes extremely slow with it. I'm hoping to be able to find a better one that can support the higher charge needed for the phone, in the meantime I'll be leaving the phone down while charging I guess.

+1 same thing for me too. I was so worried thought it was a problem with the charging port but it seems the problem is with the charger cable. Using other cable is no issues.

Obviously it pops out very easy. I'm on my 3rd Samsung Micro USB cable, all are same.
But then I've tried my friends Galaxy Ace cable and it was fine. So you just buy a different Micro USB cable which will have same 2A output like stock one.

I. too, was worried when i first got the fone.... but it's the stock cable... tried another cable from another brand/manufacturer and it fits perfect.

I seem to be quite lucky. My stock cable fits nice and snug. I can even dangle the phone upside down holding only the cable and it wont come out unless I swing it or tug it harder lol

If you compare the stock cable with other cables you'll see that the plug on the stock cable is usually shorter than other cables by a millimetre or 2 so the little prongs on the plug probably arent grabbing onto the slots of the phone

Mine 2. I just stick blue tack on it

Yup, same here. I find the cable that came with my wife's Kindle is the best fit - needs a real pull to detach it!

[Q] charger port falls out. is it your microusb port or your microusb wire?

Hey everybody. I know that there are threads on the issue of oem charger wires falling out of the note II's microusb port. I wanted to crrate another one because none of them conclude that it is a dodgy microusb port that causes the oem wire to fit loose or fall out. Ill explain why I believe that the reason these oem charger wires are fitting loose or falling out is a result of a dodgy microusb port, and not a bad oem charger wire. I had the opportunity to test this issue on 4 devices. 2 of the note II's had this problem, the other two didnt. So, I took a different oem wire and plugged it into the 2 note II's that were giving me problems. When I tried another wire, it felt alot more snug into the devices that I had problems with. Thus, I thought the issue was a bad oem wire that came with the two devices I was having problems with. Here is where the scenario gets confusing. I have a samsung smart dock that connects ny Note II to my tv when the dock plugs into tge note II's microusb port. When I plugged the 2 devices that had the problem of tge oem wire falling out, the content that showed on my tv display would flicker. When i plugged in the other two note II devices that didnt give me a problem with the oem wire fitting, the content on my tv display wouldnt flicker! That is why I think that these 2 devices have a faulty nicrousb port.
What does everyone think? I would like your feedback before I decide to order a replacement microusb port. Thanks for your time.

I had the same issue and it turned out it was the microusb of the charger that was worn out and it would easily come out of the port. I tried the sub cable of the galaxy s3 and it was snug. Also same with fitting a usb otg.

Because I tried the same damaged wire on my S3 and it was lose. I tried a bunch of other usb cables on my note2 and it fitted tightly.

It's the cable that Samsung supplied for sure.
Same issue here, but *only* with that cable.

Strangely, mine occurs ONLY with the cable (out of the box) AND ONLY with the Note II. If I plug in a different USB cable on my Note II, it's fine. If I use the USB cable (out of the box) with some other device (like my BlackBerry), it fits snugly! Weird. They hate each other. :laugh:

That is strange, have you tried other wires on your note 2?

Ive pretty much had the exact scenarios with 2/4 note ii devices I owned. The only thing I cant wrap my head around is this: if the wire is the problem; why is it that when I plug my device into my smartdock via the microusb port, which connects to my tv, the output on the tv flickers.Reason why I think it is a dodgy microusb in this case is bc the outut flickers on the tv only with the 2 devices that had the problem of the usb wire fotting loose/falling out. What do you all think?

[Q] HELP ME!!!

My Galaxy Nexus isn't charging or connecting to my computer. I've tried different USB ports, wall adapters, and USB cords and nothing. I don't really want to replace the charging port. What can I do?
Thanks in advance.

Delete this thread!
I accidentally put this in the wrong section! Thanks!

Check the charging port for Lent and stuff with a little pin or something..
That's what happened to me in the past
I cleaned it out and start to work again

Of what cujo said didn't work you have no option but to replace the port or buy an external battery charger.

In a pinch you can rig up a temporary charger using the POGO pins on the right side of the phone. Just wire the corresponding red/black wires from a cut up USB cable to the correct pins (you can find the pinouts online). The trick is getting the wires to stay on the pins - you can try packing tape. I know this is kind of a dirty solution, but it will work in an emergency until you can replace the usb port.

Well, there is no guarantee that it is the USB board - but you can purchase one on ebay for under $10. The part includes a usb jack as well as a ribbon connector that connects the jack to the main board. There is, however, a chance that you have a faulty main board, in which case, replacing the USB port is not going to fix your problem but the only way to really test that is to buy the part and try it out.

That's for a Verizon Galaxy Nexus, I don't remember which one you said you had but you'll want to be sure to get the right one.
