I got this used S7 Edge, Verizon model. I have set it up, charges well... but now I realized that when I connect the USB cable to the PC, nothing happens, it just charges. Tried with multiple cables and ports. Installed the drivers from here, installed the Samsung "Smart Switch" software (that does update the drivers also).
Nothing.
I have enabled the Developer mode and there, under USB Configuration it says "MTP". Clicking on it brings up the other options, but touching any of them doesn't change the "MTP" setting - for example touching "Charge this phone" leaves the MTP selected. And not working.
Any ideas?
I have returned the phone.

I'm using the Google I/O Limited Edition Samsung Galaxy 10.1" tablet. Connected and developed with the device fine on my Windows 7 machine until the 3.1 update last night.
Now, when plugging in the USB, the new USB debugging icon (the Android bee) shows up in the tablet's tray. However, Windows 7 doesn't find the device. I've tried power cycling my PC and the tablet. I've tried disabling USB debugging several times. I've installed Kies, but it does not successfully install the required drivers. I attempted to install the driver listed on Samsung's page for the device, but it didn't appear to do anything.
I was actively developing an app for tablets, and this has ground my progress to a halt. Anyone else experiencing this? Have a fix?
Have you tried a different USB port (on hub) or a direct USB port on the motherboard?

Yeah, that doesn't do anything.
Well mine wasnt working all i did was take the usb out uncheck usb debuggin and plugged it back in and it worked..
Yeah, I've tried enabling/disabling USB debugging, plugging and unplugging the USB. Still nothing.
Again, the behavior I'm getting is that the tablet is indicating that USB debugging is on when I plug the device in. I get the USB debugging icon in the tablet's system tray. But Windows 7 just isn't seeing it. This sure seems to be a driver issue.
Finally got it working. It took doing a factory reset on the device.
I had to turn off usb debugging, then plug usb back in.... tablet said that I had to disable bluetooth, disabled and it worked pefectly! So could it possibly be a problem with bluetooth!?!?
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 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.
When I connect my 6P to my Win7 computer with the supplied USB cable, I get a notification asking me to choose:
"Use USB for: charging, power supply, file transfers (mtp), photo transfers (ptp), midi"
I would have thought files transfers would be the right choice to use with adb, but that doesn't work (devices list on computer is empty). ptp works fine.
Is this normal? Is there a way to always choose ptp, so that I don't get a menu on my phone every time?
EDIT: I see that Developers Options includes "Select USB Configuration". This is set to MTP, but that doesn't help. It still defaults to charging and I must choose PTP rather than MTP when I first plug in. BTW, I'm on the 5 Oct Nougat, but behavior was the same on Marshmallow.
Hey guys. I've got an Exynos S7edge (unlocked) and I can't really recall the last time I actually connected it to a PC through USB. I bought a new SD Card and wanted to move my stuff and as I connected the cable, I got a message saying "The last USB device you connected to this computer malfunctioned, and Windows does not recognize it". Going to device manager it's listed under USB Controllers as "Unknown USB Device (Device Descriptor Request Failed)" with "Windows has stopped this device because it has reported problems. (Code 43)" and "A request for the USB device descriptor failed." on Windows 10.
Seeing that, I tried to test it on my brother's PC (Windows 7 Home) and it still didn't work even with 2 different cables. When I got to school I tested it on the school PC and voilá, it worked with both my cable and a friend's cable. It told me that "This device can be faster if you plug it to a USB Fast Port" or something, but it worked to my amaze, while it didn't on my teacher's personal PC (All USB3.0 ports) . I've tried all the ports on his pc, my pc, and my brother's one. What makes the school PC different? I really want to be able to connect my phone again. Also, another S7 works on my PC and another phone also does.
What I've tried:
Uninstalling Drivers on Device Manager, editing Registry Keys, deleting OEM#.inf driver packages on cmd, restarting both the pc and phone, resetting bios, all usb ports on my pc (USB3.0 ones don't even report the device when plugged)
I'm really desperate.

same here, i think the usb port is broken, asked on service 20e cost the board anthe replacement costs about 40e
Similar usb prob
When i plug in i get the JUST CHARGING notification? I know all about usb debugging and developer menu.. Tried all the usb transfer modes.. Also tried various drivers and no drivers with win7..
Only possibility i think is bad wire? Tried two? Could be coincidental unless there is something I'm missing??
Can anyone suggest how to make windows 10 recognize the phone when connected via USB cable?
Latest official android version and USB debugging enabled.
Which cable are you using for connection to the computer? the cable that comes with the phone is for charging only, you'll need a data cable for connection.
Some users have reported issues when flashing or sideloading using a USB 2.0 cable. The cable included with PH-1 is USB 2.0 and is primarily intended for charging. If you're flashing or sideloading PH-1, we recommend using a high-quality, spec-compliant USB 3.0 (or higher) cable.
ive used both 2.0 and 3.0, but never the 3.1 USB C style. never had an issue, but some of the cables look premium and are cheap crap that connect and disconnect on a whim because the pins arent contacting unless the cable is perfectly straight
I'm using this cable: https://www.amazon.com/gp/product/B01N5KL10L/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
It is supposed to be a data cable and looks pretty decent.
Are any special drivers required ? ( I have installed the USB driver found on the Essential support page but no dice)
I have those same cables, they are a bit touchy when it comes to staying connected especially in a USB 2.0 port. Make sure you're using a 3.0 port and once it connects, don't move it much. Not a great solution I know but what can you do.
I tend to leave Device Manager open when I install new hardware. It often helps understand the sequence of things. Do you hear the Windows Device Connected Sound? If nothing is showing up there, it's the USB cable
Well.. I got my phone last Wednesday and I just got the issue when I got USB3.0 to USB C cable last Friday. (my main PCs do not have USB-C port)
The symptom is;
connecting USB cable and change connection mode to "file transfer" or MTP, it looked going to connect, but actually failed or disconnected when I tried browse the device or copy files.
After few research, I could resolve the issue.
Here are the what I did.
First, I have to download and install USB driver from Essential home page. (check "Essential Developers" page. I cannot add link here yet because I'm newbie here.)
Second, Now I got connection, but still the connection was unstable especially when I copied big files (about 200~300MB or more). The issue could be resolved after turning on "Disable USB audio routing" option in "Developer Options". (You should enable the "Developer Options" first)
Third, Now I have no problem on Windows PC connection, but I got a problem with Ubuntu 16.04. And I have found the it happens only when I connect it via USB hub. After connecting to PC directly, the issue has gone.
I have no problem on USB connection with my PCs now.
