4.3 Charging Issue - Media Device

Last night I updated to 4.3 via the very useful thread here, http://forum.xda-developers.com/showthread.php?t=2145848
I was in situation "A" with a completely stock Nexus 4 and the side load went without a hitch. I was able to charge my phone from my wall charger last night with no issue. Today at work I realized that my phone was not charging from my PC via USB cable like it usually does. If I disconnected and reconnected I would see "Charging" on the Battery page for a split second then it would change to "Not Charging" and the phone would notify me that I was connected as a media device.
Trying to troubleshoot the problem I had rebooted the phone and the PC, no luck. I tried turning off the check box that set the phone as a media device and when I unplugged and replugged in my phone it started charging again. To test my theory I turned the "media device" option back on and charging stopped right away. Has anyone else seen this?
Steps to duplicate:
1) Connect phone to PC via USB with Connect as "Media device (MTP)" checked (Settings -> Storage -> Menu -> USB computer connection)
2) See that the phone is not charging.
3) Uncheck "Media device (MTP)"
4) Unplug and replug in USB cable
5) See that the phone is now charging.
6) Re-check "Media device (MTP)"
7) See that phone immediately stops charging.
Not sure if this matters but the PC is running Windows XP. Up until today I have had no issues charging and nothing has changed configuration wise on the PC that I know of.
Thanks,
Eric

A friend of mine just had the problem. It seems that, since 4.3, you can no longer charge if MTP or PTP is activated AND your peripheral is not recognized by the system. I mean, since it is work computers, I assume you do not have privileges to install drivers for your phone. And so, it won't charge until you deactivate the MTP fonction. At home, where your phone is properly recognized and drivers are installed, no problem.
Another solution is to find a "charge only" usb cable, like the ones delivered with external batteries for example. We tried it, and it works also even without deactivate MTP or PTP.

Same Issue. On two different devices out of the box.

I own two Samsung devices and they both have the same issue. I have tried different power cords, different USB 2.0/3.0 slots on a Linux laptop, Windows laptop, Mac Mini and Rasperry Pi, turned on developer mode to no avail. The few things I do see that both devices when plugged into an outlet they say Charging (AC). Once unplugged and plugged into a USB port the nav title bar hides and comes back with the battery icon with a red X and stating discharging. I have yet to find a fix for either.
- Samsung Galaxy Tab 3 10.1" 2013 GT-P5210ZWYXAR 4.2.2 Build JDQ39.P5210OUEAMK1
- Samsung Galaxy Note 8 8.0" 2013 GT-N5110ZWYXAR 4.1.2 Build JZ054k.N5110OUEEMF2

Not a fix. Just a possiable answer.

Android 4.4.4 CM 11S USB Charging Issue Resolved
Hi,
I had the same problem with my OPO. My previous device was JellyBean and I could charge even when it was connected as Mass Storage.
My new device used to connect as MTP by default and hence would not charge. I charge it from my work PC which has blocked media transfer through USB and that was the real problem. When I uncheck MTP and connect my device, it would charge. Since my Home PC has no such settings there is no problem when I connect it to that.

6P & (no) USB computer connection

Is it just me?
My computer will only see my phone if I plug it in while it (phone) is turned on. If I power on or reboot the phone (while connected via USB) it never shows up. I have to pull the USB cable and plug it back in. I tried multiple computers JIC and same results.
I AM rooted (systemless) if that makes a difference. I guess I'll unroot to see if it has any affect. Hopefully I don't have a bad device.

Rooting shouldn't have any impact. I have to toggle the USB connection type every time I plug into my PC. PTP seems to be the only one that recognizes for ADB. Fastboot works fine.

Thanks Fury, I did notice that as well. MTP would get toggled @ each plug in, but I'm talking actual connection detect not type of connection detected.
Can someone confirm normal operation on their 6P for me. I contacted Google and they are telling me it is working as designed. This would be the first phone that I have owned that is not recognized by a computer during reboot or power on. Charging seems not to be affected, only "data" connectivity...

USB Type-c port : bugged or broken ?

Hello guys, here is the bug I experience
First of all i'm sure the cable isnt guilty as I tried two different cables, with one of them being new, getting the same result/bug
Whenever I plug something to my usb type-c port, it can ONLY and ONLY charge !
When i plug the phone to a PC, it won't recognize a phone is plugged ! It charges, but I don't have the window where u can choose between MTP, Charging,...
Of course I have enabled : USB Debugging, and switched from "Charge" to "MTP" in dev options
Even the USB otg doesn't work (with "OTG stockage" enabled ofc)
From times to times I could connect the pc to the OP5, but by plugging / unplugging the cable like 20 times... And now it's worse as it doesnt work at all !
It used to work perfectly in the past , is it possible the system can bug to the point this bug appears ? Is the type-c port broken ?

I have the same problem, the USB port can only do slow charging. It doesn't connect to PC/Mac and doesn't dash charge either. Taking it to service center as i'm pretty sure it's a hardware issue with the USB port.

Try downloading OnePlus USB drivers on pc you connected device to. https://www.androidfilehost.com/?fid=673368273298966498

MTP should work without those.

No it's not an issue with the drivers. The phone used to get detected fine and would do dash charge properly earlier, it suddenly stopped working.
I visited the service center, they confirmed my suspicion, it was an issue with the USB port module. A hardware issue where some of the pins on the USB module stopped working for reason, and as a result phone wouldn't receive connection from the cable. They replaced the module for me and the phone works properly again.

Windows 10 HP laptop doesn't recognise the phone.

Guys I'm trying to connect my phone to laptop but phone doens't get recognised in the laptop. The device makes sound and so does the laptop. No pop-ups in either of devices. The phone starts to charge but no option in the notification shade to change the mode of connection though. I've tried with turning on the usb debugging too, but no help.
Laptop pups up an error message later that the "LAST USB DEVICE YOU CONNECTED MALFUNCTIONED. WINDOWS DOES NOT RECOGNISE IT".
Is this falut of my charging port or of laptop? Or windows 10?
I've tried connecting to all other ports and with different cables. My all other android devices connect though. Please help.

I've had this issue with pen drives and my USB port had an issue(short circuited).
Check these :
Try running devices troubleshooter from control panel.
If the phone is charging properly by using the same cable , it's probably an issue with the laptop.
Is it on pie?

Sir I've tried debugging thing already and set the option to MTP. I've run troubleshooter too but windows couldn't identify and solve the problem. I'm guessing the problem is with windows 10. So I've decided to installed windows 7 in a different drive. Maybe that'll solve the problem.
Phone is running on Oreo.
Note:- I think micro usb has four pins. One among them might be a ground pin. One must be for charging and other must be to transfer data. Correct me if I'm wrong.

I had several times repairing phone with broken micro usb connector, it has 5 pin to be soldering on it. 2 for the power and 3 for data transfer. If the cable is fine for other devices then maybe the problem is not from the cable itself. I had an experience like that case before that if the notification from the pc says connected device is malfunctioned, that may caused by when u first time connected the phone to the pc, the device is disconnected when it still trying to instal the driver. When u connected the phone to pc check on the device manager, if u see "!" icon there, then theres the problem, ur phone driver not installed properly, u can try manual instal of device driver from there.

Last usb device you connected malfunctioned. Windows does not recognise it
"USB device not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it” always appears in Windows 10 and Windows 8.
And the reasons for the issue contains:
The currently loaded USB driver has become corrupted or unstable
USB drivers need to be updated
USB drive may be entering selective suspend
USB has some damaged files or bad sectors
USB drive has not been formatted correctly
For different reasons, you need to take different measure, but you can directly format it via AOMEI Partition Assistant to solve the usb device not recognize issue.

The USB port itself was damaged. So I got replacement and now the new phone works fine with same laptop. Thanks you all for your replies.

My phone won't recognize being connected to any computers after trying to usb tether

Hi all, I haven't been here for a while now, but I figure that this is the best place to put my issue besides maybe reddit. So I was trying to activate USB tethering yesterday as i do a lot in order to play some games on my computer since i don't have access to any ethernet, and something went wrong and it didn't activate despite having hit the switch on the phone. I unplugged my phone to turn it off since my computer hadn't recognized the tethering and tried to activate it again, but this time my phone only made the charging noise and wasn't picking up my computer at all. I then restarted my phone to see if that was the issue and got the same result. I then tried to plug it into my laptop to see if my computer was the problem and it did the same thing.
Today I tried plugging my phone into my laptop with my usb-c to usb-c cable (instead of my go-to usb-c to usb-a cable that came with the phone) and got some signs of life from the laptop, it makes the sound that says its plugged in, but the phone still only charges and the laptop picks up my phone as "USB root hub (USB 3.0)" and "Intel USB 3.1 eXtensible Host controller-1.10 (Microsoft)" in device manager. I also just tried clearing the cache in recovery but nothing has changed. Does anyone know what's going on here and how I can fix it?
Unrooted (duh), AT&T model (sorry idk the model numbers like i used to), latest updates and security patches etc
EDIT: power cycled it (let it die and turned it back on a few times until it wouldn't turn on again) and charged it back up again and that seems to have fixed my issue.
