[Q] SM-G900H trouble with USB connection. - Galaxy S 5 Q&A, Help & Troubleshooting

Hi all.
Trouble with my S5 SM-G900H!
I have a fresh install of Windows7 SP1 64bit. After connecting the phone cord (factory, MicroUSB 2) relatives in Device Manager appear strange device: "Conmeon Suspend", "CDC ACP", "CDC NCM". Set Kies3 through it put the Samsung USB-drivers. None of these devices is not defined.
After you connect to a computer on the phone is turned on and charging no more signs of connection to a computer is not.
In the "Tethering and Mobile hotspot", even when the cable is connected, item "USB tethering is hidden," written under it "No USB device connected."
Connecting to Windows7 32bit gives the same result.
After connecting to a computer with Linux on lsusb shows the device "Conmeon" and nothing else in the system appears.
Made a hard reset to factory settings - does not help.
How to revive the USB-connection?

Did you installed latest Samsung USB device driver??

Not sure about the G900H, but other variants use *#0808# to access it. Your settings there should be MTP + ADB & AP.

[Q] Problems with connection to PC

I can't connect it to PC . I mean , i conncect the usb cable to my phone and my pc ... my phone shows that it is connected to my pc ... but there is nothing happening . I mean the PC doesn;t find the my phone. What should i do. Ty everybody! Sorry for my english
Well,may i know on what OS are you trying to establish USB connection? WM/Android?...For WM, have you installed windows mobile device center on your PC and tried syncing? As for android,try installing the right version of HTC Sync on your PC. Also, ensure you tick 'USB Debugging' under Settings-Applications-Development. For a few android builds, there will be a notification, prompting you to turn on USB Storage after you connect the USB cable. You have to try all those first before moving on to advanced troubleshooting like manual driver installation,android sdk,hard rest,etc.

Cannot Connect to PC AARGH!

Hi,
EDIT * I have found a solution in that I can connect via WI fi so that's pretty good but if anyone can help me with the USB issue, it would still be appreciated. It seems that the Wi Fi connection is more limited as I am unable to view things in explorer *
hoping to get some help using my USB to connect to my PC. I've installed Kies but when I try to connect to my PC it just keeps on trying to connect but never actually does it.
I have looked for guidance on this but keep coming across the instructions to go into 'about phone > USB settings' etc etc. However, I do not have a USB settings in about phone. In fact, there is nothing at all about USB in About Phone. I do have a 'USB Utilities' in Wireless and Networks but all that gives me the option to do is 'Connect Storage to PC'. I have a memory card in my phone.
When I do connect to the USB cable, with Kies open, when windows 'finds new hardware' it keeps saying a problem occurred during installation.
Please can anyone help me out? All I want to do is basically drag and drop some files from my PC to my phone. Thanks very much for your help.
Settings --> Applications -- Development --> USB debugging.
Thanks for that!
It got me a little further. I also unmounted then remounted the SD card. However, when I try to connect via kies I now get the message:
Reconnect the device in Samsung Kies (PC Studio) mode. Current connection mode not supported by Kies.
What am I doing wrong? Do I have to re click the USB settings on the phone before connecting to Kies now that it's installed the hardware on my PC?

Turn off USB-Debugging
Don't connect phone yet
Open Kies
Open the Tools menu -> Troubleshoot connection error
Go through the guide and let it reinstall the drivers.
Connect you phone, and let it connect
The default setting has the USB debugging tick greyed out. When I select it, it asks me if I want to allow debugging.
Do you mean that I shouldn't allow debugging and then connect (after reinstalling Kies) or should I allow it and connect? Sorry for my noobishness, Android is all completely new to me.
You should untick the USB-debugging - Then reinstall drivers NOT entire Kies
OK, it's unticked and I'm reinstalling the drivers via troubleshooting.
Do I need to unmount then remount the SD card before connecting my phone? Thanks for your help btw.
Shouldn't make a difference
Bah, I still have the same problem. It just says that there was a problem installing the hardware when I plugged in the phone.
After reinstalling the drivers, i shut down Kies then reopened it. I then plugged in the USB and then plugged the USB into my phone.
When I first installed Kies yesterday, Microsoft Active Sync kept on trying to activate and ask for a CD. It kept on holding up Kies. In the end I uninstalled Active Sync. Also, I still have Samsung PC Studio on my PC from when I had a Samsung a few years ago. It was one of those old slider phones, not a smart phone. Could that be part of the problem? I was hoping to keep it because it's proved to have the best media player I've ever had.
I just don't know what I'm doing wrong here.
Try without restarting Kies.
What part of the drivers aren't installed? (Check device manager)
In Device Manager, under Portable Devices there's something called Android MTP that has an exclamation mark next to it. It says it's not configured correctly and that 'No driver files are required or have been loaded for this device'. I'll reinstall the Kies drivers now.
Thanks for this help mljjlm
P.S. Now that I've unplugged the phone, the MTP thing isn't showing in the device manager list anymore.

Of course, it's a part of the phone, and it should not be plugged in because they would have to force a reboot when reinstalling drivers (which might sort your problem btw)
Reinstalled the Kies Drivers and then plugged in my phone but got the same problem. It says a problem occurred. Same device now has a problem in device manager. Maybe I should just uninstall everything and restart? Should I uninstall the old PC studio too?
Just try the reboot without uninstalling anything and then plug the phone in when your pc has booted
Argh! Still didn't work! I think there must be a problem with my PC, well, I'll try doing full uninstalls and reinstall it all. I have to go now as well so I'll have to try again tomorrow.
Thanks very much for your patience mljjlm. It has been greatly appreciated
Are you trying to just transfer files back and forth? If so... forget using Kies.
(I don't have a micro-USB cable with me currently, so this is all from memory)
Just remove the drivers from your device manager so it's like your machine has never seen your phone before. Then on your phone enable usb-debugging.
When you then plug in your phone, you should get a usb icon up top on your phone's display... pull the window-shade down and click on the USB connection button. You should get a fullscreen window on your phone that says something like USB Connection with the friendly android waiving.
Now your PC should see your phone as a standard USB mass storage device.
try plugging the usb cable in another usb port on your computer and than try again.

You're using Kies, that's what you're doing wrong. You said in your very first post you wanted to be able to drag and drop some files from your PC to your phone, so use USB debugging (say yes when it asks you) and Windows Explorer.
If you are using a custom rom like Checkrom Revolution you will need to install the kies support from kitchen pro.
Also are you using the cable that came with your phone?
I have found a few microUSB cables that will allow charge and wont allow data transfer like the new ones for nokia devices and some blackberrys.
It worked! The USB debugging thing!
Thanks to everyone who helped me out. The forum said I was limited to 5 thanks per day so if you didn't get one of the thanks I apologise. Thanks very much!

My PC Doesn't recognize my G2

So I'm trying to connect my phone to transfer some files but I no longer get the USB method selection, the phone is only charging.
I also get a message from Windows after connecting via USB: "one if the USB devices attached to this computer has malfunctioned and Windows does not recognize it."
I tried re-installing LG united mobile driver but it didn't work. any suggestions?

[Q] USB connection not detected by Linux OS

Hi.
I am trying to connect my Samsung S4 by USB to my laptop running Fedora 22. The phone charges, but there's no connection detected by my OS. The device does not appear in the list of usb connections('lsusb' listing), and there's no indications of connection events record('dmesg' listing). I'm pretty sure I've done all necessary step I'm aware of for it to work: USB debugging is enabled, the phone is on, I've installed the libmtp and android-tools packages. Still no connection shows up.
Is there a step I'm forgetting?
If there is a bug, what is it and how can I correct it(or get around it)?
The phone is running Android 4.4.4.
Thanks.

If MTP, PTP does not work (If you can't acces phone storage with PC)

My Win10 Insider Preview machine did not recognize the phone. Nothing happened when I connected the phone and I could not access storage of the phone.
Below is the solution for it:
Go to Control Panel - Device Manager - LeMobile Android Device (could be under a different name. Choose the one that is your phone) - Update Driver - Manually Install a Driver - Let me pick a list of available drivers on my computer - MTP USB .

Uhm ... when you connected the phone to computer you changed the mode on phone from USB charging to MTP mode ?
In my Win10 x64 build 14392.447 not problem to see the phone in MTP mode after changing mode on phone.
Alternative solution is to use KDE Connect app over Wifi. Bonus is that once set up, it is possible to push files from the phone to the PC without any interaction on the PC side - e.g. useful if the PC doubles as a file server.

Both of my home & works computer (Win10 14959) failed to detect it as MTP or PTP drive. Might have been due to those having previous phone's drivers.
But I faced same problem with fresh out of the box Win8 laptop.
No issue with the MTP, however I can't seem to get adb to work. list of devices attached is showing empty.

Wanted to add my voice here too that I did the same - I had to clean up previous drivers I had installed over time for varios phones and different ADB versions like the one from clockworkmod - once I cleaned that out and installed google drivers from SDK PTP worked and I was able to do Helium restores
I had issue on my Win10 PC, but I found that after I disabled USB debugging, it would work as MTP/PTP, but not for ADB of course. So apparently, I have to toggle USB debugging ON/OFF to switch back and forth from MTP and ADB.
Small pain in the butt.
Solution.
I had the same issue. Drove me NUTS for about an hour. In the end, simply unchecked the USB DEBUGING in developer settings. This will make it pop up immediately.
Update:
I clearly should have read the post above mine first.
