You'll need external power to power it

its a pendrive, which should work unplugged. It just doesnt seem to even recognize that its there. Do you think the cable is defective?
In the usb otg tutorial video in the accessories section it shows that plugging in the cable without anything attached to it should trigger a notification. If it doesn't, it's probably the cable

okay, I guess the motorola xoom cable does not work for some stupid reason. Or its defective...well ****.
I guess, it's missing a resistor to trigger OTG mode.

in this thread (http://forum.xda-developers.com/showthread.php?t=1092493&highlight=usb+otg+resistor) you'll find detailed instructions on what makes one cable work and another one fail. apparently, you'd have to open the micro usb plug and connect pin 4 and 5. the connection between pin 4 and 5 determine, what kind of connection it is: charging, sync, usb otg, mhl, trigger download mode... and indeed, that is done by putting in different resistor strengths.
I got one of these, only £2.50 shipped and works perfectly, its great fun plugging in a mouse!

Ok I have the following problem:
I bought g1 without usb cable (original one is curved) and I tried to connect it to my pc with regular usbmini cable from my ext. Hdd and charging works but I can't transfer data cuz it doesn't recognize my device and on my phone it doesn't even show it in notification bar. So my q is:
Does it make a difference if a cable jack is curve or a regular one and does it make a difference for this phone? I don't think that usb port on the phone is broken cuz it charges. Thanks in forward.
I used a cable that is for charging a PS3 controler and worked great.

Solved
I solved it by reinstalling the CyanogenMod. Thanks for help
I have an otg cable, yet none of my accessories work with it and my RAZR MAXX. My question is whether or not I need a powered hub when using the OTG cable. I have seen set ups of other android models using a SIXAXIS controller and otg cable, yet no hub. In this case, it the powered hub not needed since the controller itself is supplying its own power?
Thanks,
Neverused
USB controllers don't work?? I'm interested in this as well

Download USB Device Info:

When you open the app you should see 0 devices under Android and Linux tabs. Now connect just your OTG cable nothing plugged into it and hit refresh, something should show up, usually under the Linux tab that identifies the USB host. Even if the USB host doesn't supply power this will still work as I have tested it on my Touchpad which has no OTG power.
If you saw something appear when you connected the OTG cable, than OTG is in the Razr M. Now try connecting your gamepad and refresh the device list. If its not showing up then there is either something wrong with OTG or you need external power. This program will ID any USB device connected, even those which Android doesn't support since its just matching the device against a list it has. Try getting a USB keyboard/mouse working ad those are universally supported on Android and would confirm if USB host works.
Questions go in the question forum too...
Here's a dumb question. I just ordered a female USB to male micro USB. I wanted to be able to yank pics off my camera and drop them on my phone. Would I need an OTG adapter or does that plane adapter work?

An OTG cable has a extra pin in it that is tied to ground in a OTG cable which tells the hardware to switch to OTG mode. A regular USB cable will leave this pin open.
If I'm able to peel open this adapter that I got, and jump pin 4 to 5 should it work as an OTG cable?

Its possible, as shown here:

For me I'd rather just buy an OTG cable, but if you have regular microUSB cables laying around, go for it.
Bought an OTG cable
Bought a simple OTG adapter from newegg. So far....plugged in a mouse and my camera. Both work flawlessly, my camera gives me the choice of either either MTP (?) that goes straight to gallery and image import, or Storage which prompts to a new usb mount. Have not tried a gamepad yet, I have 2 floating around somewhere but not sure what game to try.
What do you think about a wireless storage? Think about those SDCards with built-in WiFi. If independently powered, they could be used as kind of external memory with WiFi-Direct.
What do you think? Crazy or possible?

Thought about Eye-Fi already. This thing needs a power.
Ok, now serious:
We need someone, who have: Eye-Wi, SD card reader, usb-micro usb cable converter, Nexus 4.
Two questions here:
1.Can Eye-Wi, cable connected to the phone, be powered?
2.If yes, will it recognize the device and connect in any way?

Eye-Wi sounds really interesting.
Sent from my GT-I9103 using xda app-developers app
if i could find my Eye-Wi, I would try this, but in my other test with a micro-usb micro sd adapter and micro-usb y cable, the adapter would not receive power from the phone's micro-usb charger....the Eye Wi I had actually had the SD Card Reader built in, in order to test this you need you're phone's charger, micro-usb y cable, and Eye Wi...they way it should work is that your phone charger plugs into the y-cable the y-cable female micro usb end goes into the phone and the Eye Wi into the USB...if that doesnt work disconnect the y cable from phone and plug the Eye Wi into the phone charger directly to see if that will power the Eye Wi and if your phone sees the wireless network...this alternative if it works is fine if you're by a wall outlet all the time, but travelling on say a plane or train then no, you're better off with a self powered wifi drive/reader.
I installed it in my dash and removing it is a pita it was working perfectly fine but for some reason it wasnt showings charge or turning off or on with the car it just stays on i tried restart nothing happens i tried unplugging usb from powergen and plugging back in no result
Also if i go to usb rom under fixed installation i am able to check box and uncheck also did nothing
I am using nexus 7, timurs usb rom, otg cable, original charging cable and powergen usb charger
Please help thanks
Anyone???
I'm also using Timur's kernel with USB ROM for my car installation. I know that it can be very picky on the order the USB plugs are added (data and power). It may seem simple but remove the the OTG cable from the tablet and remove both the data and power legs from the OTG as well. The follow the order listed by Timur on his website:
To activate charging, you must first connect your external power supply to your OTG Y-adapter - then plug the OTG adapter into your Nexus 7 - and then connect any slave devices.

Hopefully that should get you back up and working. I completely understand how frustrating it is to have everything plugged in and see that tablet isn't charging, especially when its difficult to get to the Nexus itself.
does anyone have a easy charging solution these car chargers dont work
and a good otg y cable
You could try using a power inverter which will give you a standard US plug from the cigarette lighter. From here, you could plug in a regular outlet adapter. I found this to work pretty well with my own set up and managed to get one pretty cheap at Walmart. As for a good OTG y cable, your best bet is probably to go on Amazon and find one with a lot of good reviews. They can vary in quality and some of the cheap ones I've gotten from China have flaked out after a short time and little use.

Not seeing usb power
I had the same issue. I was using a 90 degree adapter into an OTG cable and my n7 wouldn't go into fixed install mode. Turns out my adapter cable was stopping the n7 from recognizing power. I removed the 90 degree adapter and plugged straight to otg and it worked as advertised. The issue was found during my bench testing on a 12v powersupply. I still have to find a 90 degree otg cable that will work.
So... try a different cable or if you have an adapter between the otg y cable, that may be the issue.
I'm on 4.4.2 stock rooted, and using a MHL/HDMI cable I bought from eBay (http://www.ebay.com.sg/itm/271413587689).
When I plug it in (including the charging USB cable), my Note 3 detects that a HDMI cable has been connected. However, nothing appears on the TV (I tried different HDMI ports). I have also tried restarting my phone as per the instructions on the eBay page.
What does happen is that the display on my Note 3 lags and stutters when the cable is connected. But no matter what I do, I can't get the screen to be mirrored on my TV.

No. o.o
BTW, I disabled some services. Are any of them required for HDMI output?
Bump. Please help, thanks.
