[Q] Usb problem. - Galaxy S III Q&A, Help & Troubleshooting

Hi everyone.
I got this problem with my Galaxy: when connecting with usb cable to my pc, the phone isn't recognized at first try. Sometimes it starts the explorer on pc but I can see no files in the phone memory nor in sd memory. After unplugging and plugging back again 3 or 4 times it eventually works properly.
Can you help me?

Try to clean USB port in your phone or use different cable.

R: [Q] Usb problem.
Already tried it. I've also tried all the ports on pc..they all get the same problem. May it be because of the lock pattern?

Clean install of USB drivers .

I'm having trouble connecting to my Windows 8 laptop. I have reinstalled USB drivers and whatnot, but usually my phone is not recognised at all. However, if I use SGS3 Easy UMS app from Play Store to toggle MTP off and on while connected to USB I get the PC to recognise my device after a short while. It's so strange.
Usually I just use Samba server to transfer stuff because getting a USB connection is so complicated. USB (MTP) works normally with my Windows 7 PC at my workplace, though.

I'm going to try Easy UMS.
I don't have the possibility to connect wirelessly bc I don't have any wifi router at the moment.

Problem using the SGS2 as an External USB drive !

As per the heading, I abandoned carrying a USB memory stick years ago, instead I have a 16GB memory card in my phone and carry a 15CM micro USB to USB cable in my pocket, this way I can use my phone as a USB drive when ever I need it, but I have a problem with my SGS 2
1) the drive seems to randomly disconnect itself whether or not it is transferring data
2) the option to ask me what I want to do every time I connect my USB cable is missing, forcing me to go to settings--> wireless and networks---> USB utilities, just to use my phone as a USB drive ....... VERY IRRITATING
does anybody else use this feature, if so what are your findings ?
I have a similar problem, it will disconnect randomly but also when trying to update and some times when trying to transfer files. I do however get the option to view files pop up when I plug it in. I made a post earlier but no one replied, hopefully it can be fixed easily. I wouldn't really know where to start though

Um, there must be something wrong with your phone. I have not done anything special to use my SGS2 as a USB drive. It's litterally plug it in and away you go.
I just plug it into the computer, the phone says something like MTB in progress, Kies connection or whatever.
Then I get the option to view all files and folders in My Computer (windows 7).
No problems whatsoever.

I don't normally use the "MTB in progress" version as the majority of computers I plug it into do not have kies loaded.
I use the standard USB drive option in settings
Bump
Anyone else having this issue

Hi,
i dont have any USB connection issues, loaded my 32Gb SD and the internal Storage full and i do use a lot the Mass Storage funktion, somtetimes the connection lasts for hours, so (Win7 32Bit).
Totally agree, the settings--> wireless and networks---> USB utilities ... tapping is verry annoying. Have to do this many times a day
Maybe someone knows an solution how to set the "Mass Storage" connection as an default?
Greetz Tokl
try multimount off the market.
You need to enable usb debugging (to prevent the keis rubish launching).
then anytime you want mass storage mode, click the multimount widget.
-- Actually just enabling USB debugging seems to set mass storage mode as default.
I have the same problem but I think it's the problem of the USB port on your PC. I plug the phone in another port and everything is ok now. You can try this on another PC or another port and you'll see. Hope this helps

1) Doesn't happen on mine. Have you tried using USB ports on other computers as it could be due to a particular USB port on a particular computer doesn't supply enough current?
2) It's irritating.

So you don't have a usb icon in the notification area? Otherwise, you just have to select it to enable usb storage.

Thanks Mate!
USB Debugging prevents Kies and bring up the Mass Storage directly
One more (very small, but annoying) issue of the SGS2 solved

When I enable debugging mode, I does indeed turn on mass storage mode and it works. However, every time I unplug the phone it reboots. I do press the disconnect USB drive button and I do eject it on my PC. It still crashes. Does anyone else have this problem?

This happened to me today, and the reason was the Android browser application running in background. Using the task manager I killed browser and then I faced no problem thereafter.
So, to sum up I guess an application running in background might be the reason.
Hope this helps somebody...
It's funny you should say that, as I hardly ever get that problem anymore, and I mostly use dolphin hd browser now

If it is connecting in download mode then the cable is perfect. Flash the firmware again to check if it is working or not

This was an issue since i had gingerbread. I upgraded to ics, didmt solve. Jelly bean, nope! I flashed neat rom, still the same.
The only it gets connected is when i turn off both my laptop and phone, connect usb, turn both on. Only then it gets connected to mass storage

[Q] VSGS3 USB Not Recognized

Whatever I do I cannot get my desktop to recognize my VSGS3, all I get is a message saying USB device not recognized. I have tried everything from installing drivers, to turning my pc on and off, phone on and off, etc. The VSGS3 worked out of box on my W8 laptop, but I need to connect to my desktop!
Try using a different USB port on your desktop!?!?

[SOLVED] No USB connected. How to solve?

My Galaxy S3 doesn't connect any longer to my PC using a USB cable.
Better said, when I connect it, it makes a sound but nothing else happens, no change in the notification panel, and under settings USB tethering is unselected. Needless to say, my PC does not see the device.
I exclude a cable problem as I have two cables (one original) that were both working. I also exclude a PC problem as the situation replicates on both desktop (Win 7 x64) and notebook (Win 7 32-bit),and the latter has not been updated or had new software installed.
What I attempted:
un/select USB debug mode
un/install Kies
un/install Samsung USB drivers
wipe cache/dalvik/data reset+ format system + restore old backup from CWM
Does anybody have a suggestions on how to proceed? Thanks for your help!
Just on top on my head-do you maybe connect it to or thorugh a usb hub to a pc.
If so try directly into a usb on the pc.

Before I had been using with success a USB hub (only the desktop only, not the notebook), since I have been experiencing the problem I have also tried a USB port to no avail.
As I stated, I am pretty sure the problem lies with the phone, in fact since my original post I have seen a similar thread at here at xda
I tried everything and at the end brought the phone in for assistance.
Turns out the problem is hardware-related, on connector pin was burned. The connector has 4 pins out of which two are sufficient for charging (which is why it was being charged by the pc) but all 4 of them are necessary for the phone to be recognized as usb device.
According to the technician to whom I spoke, it happens occasionally but is not a systemic problem.

change USB ports for PC connection

Hello folks,
As a part of idiotic ""data security"" my organization decided to block all USB connection from and to mobile devices.
Till recently, usb PTP mode (camera) connection worked and now they've blocked it as well.
The question is, whether there is a way to change the GS3 ports which it uses for usb connection so the computer will recognize it as something different then media device or camera but still will let me move photos and files from and to the computer ?
Thank you so much in advance.
YA.

If they did it properly then all unused USB ports would be disabled in device manager, the device manager blocked for anyone but admins. Are you sure its only media and storage blocked?

Unable to recognize device USB.

I have tried to connect with the device through USB with fastboot, adb, and just through Windows. It does not show up in the Device Manager at all.
Is this a hardware issue with the device? Seems odd as it was working fine and now it isn't and it has only been sitting on my desk as this isn't my main phone.
By the way I have tried this on 2 different Windows 8.1 computers and one Windows 7 PC.
Try removing all drivers for the phone and reinstalling them and see if it works. Also are there any other phone drivers installed for a different device you may have recently installed? They may be conflicting.

It should still show up in Device Manager regardless of drivers though. Just tested on a computer that has never had a single phone plugged into it and Device Manager still does not detect and devices.
Windows 8.1 has driver issues for the DNA. Though it should have worked fine in Windows 7. But I believe for a device to show up the drivers need to be installed.

try a different cable
The device should still show up without drivers as an unknown device. You can't really mess with the drivers for the device until it shows up. Also on a Windows 7 computer that has never been used before the computer should automatically pickup the device so you can transfer files to/from through Windows Explorer.
I have tried a different cable.
I am starting to think it's a hardware issue with the device itself.
what happens when you connect an OTG cable and a flash drive? Does the activity light on the drive activate?
I have not tried that and I do not believe I have an micro OTG cable. I will have to check when I am back at my place later.
Try installing HTC sync and update it and see if that installs ur correct drivers
Sent from my HTC6435LVW using xda app-developers app
Appreciate the replies. It should still detect a device plugged in without drivers/HTC Sync, but I have tried installing HTC Sync and all that anyhow. The PC's can detect other Android devices just fine(HTC One M8 & EVO 4G).

If you KNOW the cable is "good", the port may not be "GOOD". Does the cable work with another device?
The cable is definitely good(tried multiple and they work with other devices). I have been thinking it's the port in the device from the beginning, but was hoping maybe there was something else going on.
