Ive been trying to get an Wireless Xbox 360 controller working on my GNex. If i plug in the wireless receiver it stays off unless i hold the sync, but turns off after a few seconds. One time i rebooted with it plugged in and i was able to navigate the home screen for a bit then it died. I tried plugging it into a powered USB Hub and it worked great and I was able to play several levels of Dead Trigger with no issues.
It seems like the usb port isn't putting out enough power for this.
HDMI over MHL also flickers and cuts out frequently, is this also do to some weird power fluctuation? I always turn off LTE before i use MHL as i read that that interfere but that doesn't fix it.
Anyone know about these two problems? Are they related as i suspect? Is my device just defective?

I charge my EVO off of my laptop at work and I have noticed that periodically it will wake up and the little lightning bolt indicating that it is charging disappears. The phone will go back to sleep for about 60 seconds then wake back up and the charging icon will re-appear. Is this normal?
Check your charging cable. Have you dropped your phone while it was plugged in causing it to become unplugged? That happened to mine and now the terminals aren't stiff (yeah yeah that's what she said haha), so it will only charge if the plug is at an angle that causes the terminals to make contact with the upper portion of the slot.
If so, I haven't found any way to resolve that.
If not, can you provide some more details? Will it charge if it's plugged into the wall?

Charges fine when plugged into the wall. Phone have never been dropped. When I plug the USB cable in, I get the option for Charge Only, Disk Drive, etc and choose charge only. It will charge for a long while, then the screen will wake up and the charging icon will be gone, though the icon showing that the phone is connected via USB is still present. The phone will go to sleep that way then wake back up with the charging icon present again. It's very odd.
My phone has started doing something very similar only it is connecting as Disk Drive when I select Charge Only. When it does this, I have to switch it to Disk Drive, then back to Charge Only. Sometimes while its just sitting there charging, it disconnects (like yours is doing) and reconnects to Disk Drive again while Charge Only is selected. I have to repeat the steps above and its an endless cycle.
this could very well be an issue with your laptops USB chip/circuits and/or power profile.
Often times, your computer will try to power down unused components.
Depending on your laptops usb, windows and/or bios may be powering down the usb at which point your phone wakes up, attempts to reconnect (waking your laptops usb up), then starts charging again.
You might try going to your device manager > usb controllers > usb hubs > power management tab > uncheck 'allow computer to turn off this device to save power'.
I agree with it being the power save on the USB ports. You will need to uncheck the "allow computer to turn off this device to save power" for each USB port. Keep in mind on newer desktops and laptops, that there can be eight or more of the selections available for you to uncheck.

I found out that the default setting for doubleTwist media player is to make it automatically set as a disk drive upon usb connection. This setting can be changed.
Hello, I have a Samsung Galaxy Note 8.0 (I467M - Telus LTE). I have a OTG USB Host Cable and I've been trying to use a USB mouse with this tablet but it seems to be having an issue with the tablet powering down the USB mouse when it is idle for more than 3 seconds, causing it to disconnect. After clicking a button on the mouse it powers on and after a 2 second delay reconnects and functions normal until I leave it idle to start the process over again.
I do not want the USB mouse or keyboards(Tried aswell) to disconnect if left idle. It takes too long to reconnect and is quite annoying when your not consistently typing or using a mouse.
I'm wondering if this is a API issue with the usb drivers on the device or if this is a setting that can be tweaked.
Thanks for your help! (Btw the devices all work fine and dont idle out on my samsung galaxy s3 from telus. (I747))
I was streaming a movie through AllCast and halfway through, the tablet just shut down. I get no response when holding the power button in for 30 seconds, no battery icon when plugging in to the charging port. I do get a blue light from my Qi charger when I place it on the wireless pad. Device is running factory 5.0.1 image and is rooted with usb debbuging enabled. Might there be a way to do something through fastboot/ADB? Thanks in advance.

I think your device is discaharged completely & shutdown.Give it sometime to charge & turn it ON
Hey, what's up everyone?
Today I embarked on externalizing the power button on my Nexus 7, That's the easy part.
Now the hard.
What I wanna do is use a time delay or pulse to complete the ground connection to turn the screen on When power is applied. (To what I'm assuming is a time delay relay/pulse relay.)
The part I'm confusing myself on is how to do this. I basically need to know what that thing is.
It would sit between the two ground wires from the tab.
When power is applied to unknown item.
It connects the grounds for a millisecond and then release.
Resulting in screen on.
Any help is appreciated thanks alot
This $1.50 Time Relay Module will do the job, but instead of "externalizing the power button" why not leave your N7 intact and interrupt its power supply?
Settings - Display - Wake on plug​

Thank you very much.
It's a hardwire install. No battery constantly on.
It's in the early stage, so externalizing the power button may not need to be done.
Just getting the research ahead of time.
I'm not really sure if the external powered hub can wake it up, When the screen is off. Or if the USB port will act the same anymore.
The hardwire is connected to the battery board. So the USB port may function as normal. If it does then wake on plug or activity at the USB port wake up is the best outcome.
If functionality is lost at the port a secondary trigger such as
simulated power button
Or wake on Bluetooth activity
Maybe my only routes.
I'm completely open to any ideas and suggestions anyone may have.
"Wake on plug" will work regardless of USB data status or type of power source. I'd cut the [+] wire of a USB cable and splice Time Relay Module there.

The battery board is integrated with a Lipo. Did you remove the Lipo and connect a power supply to ex-Lipo's terminals? If so, what voltage did you apply and is it working reliably?
I attached a picture of the battery board from a mod I did...

We did the exact same mod.
Your bcb looks a little different though.
I too removed the board from the lipo and soldered to the Positive and negative.
I then ran from the ground to the first black wire at the connector and tied in.
I'm using a 12v downstep to 5v 3a to power the nexus.
If the USB port works regardless.
I will not need the relay module. The external powered hub will trigger screen on. (If I'm reading you correctly)
Currently on the bench it has ran flawlessly. Android doesn't seem to mind or notice that it's hardwired or that it's running continuously. Android reads out 100% battery

Yes the hub will trigger screen on but I thought you need an interface to another, controlling device. I suppose you will simply power up the hub to initiate screen on.

That is correct. I was gaining research knowledge, to hopefully get ahead of the game. Incase the port did not act the same after removing the battery. The project comes home tomorrow, Where my real test can begin.
Solved!! If anyone would like to use my way. Don't hesitate to ask.
Have a P3XL that I'm I was going to load a custom image on. But I can't for the life of me get it to recognize having any form of usb data connection.
When I plug it in, it simply starts charging, no usb notification appears on the phone for adjusting the connection, the computer doesn't make a sound, nothing.
With the very same cable I can plug in a P6 and P3 and they will immediately be detected in the device manager.
I've tried messing with all the USB settings on the phone, turning them off, adjust the default use to File Transfer / etc... (note that none of this is from the usb notification, but the actual usb settings under preferences since it's unable to detect it's even attached!)
I'd had a couple issues with the port only charging sometimes so I bought a replacement charging assembly and installed that assuming that would make all my problems go away and while it definitely fixed the cable so it charges every time, it continues to refuse to be recognized as a device.
Does anyone have any ideas what would cause something like this and what might be wrong to cause it to not be recognized AT ALL (to re-iterate, the computer literally can't detect that a device was attached it's not doing anything, both with old and brand new charging port).
(One other quirk, not sure if it's related...The phone never actually stays off. If you power it down, it will power itself back on just a few seconds later. The power button itself isn't stuck and works perfectly for all the normal functions: tapping/holding etc.. And to be clear, it never shuts itself off randomly or anything like that, it's just if you hold the power button and choose "Power Off" it shuts down and then just reboots 2-3 seconds later)
