I plugged my N7 USB in at work and I could see all the internal files. Plugged in at home and "most" of the files are there, but at least 10 folders are missing. Windows 7 on both PC's. What could that problem be?

So, if I leave my N1 connected to my PC (Win XP Pro SP3), either just idling or transferring large files (> about 50mb) it'll just dismount. Randomly.
I can't duplicate the problem exactly, but it does it all the time.
I had the same problem with my old Magic, and I've had it on various PCs.
Anyone had similar problems, or is it just me?
By my understanding, this happens if the Nexus gets insufficient power from USB to charge the battery and support the USB connection. This is usually not Nexus'es fault, but computer's fault (some computers don't have up-to-spec power in USB ports).
I always got these problems when I connected my Nexus through an unpowered USB hub. As soon as I connected the hub's power block, the issue disappeared.

That makes sense. It charges REALLY slowly on my work PC.
Thanks!
hey guys,
so yesterday i tried plugging my hd2 into the usb port on my comp, like i always do. then all of a sudden the option on the computer to open folder content from the sdcard disappears. now my phone won't ActiveSync or disc transfer, doesn't even show up at all that its connected to the comp. it just charges only. and unless i turn off and kill navipanel. it will automatically go into car more without having anything plugged into the micro usb on the phone.
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.
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.
Hi,
I have a 2 year old S8 (SM-G950F) running android 9.0 that I decided I want to root and flash a custom rom. However, when I plugged my phone into my laptop (MacBook Air), it only charges the phone and doesn't let me transfer files or access my phones storage. I've never had an issue with this before and in the past it would work as normal. I have tried a multitude of different cables ranging from the one i got in the box to other random USB-C and Micro USB cables i adapted with the Micro to USB-C adapter. In addition, USB Debugging IS turned on in my settings, i've tried turning it off and on countless times as well as revoking the USB debugging authorisations but nothing has worked. In my developer options, i've selected transfer files as the Default USB Configuration but that hasn't changed anything and there's still no popup in my notification window to switch between charging and file transfer. When I try to run Android File Transfer on my laptop it says there isn't a phone plugged in to begin with. I've also tried using my Windows partition on my laptop to see if it would work on that but that doesn't work either. I really need some help with this issue and I would absolutely appreciate any input!
