[Q] PC doesn't detect device - Galaxy S II Q&A, Help & Troubleshooting

Guys, when I connect mobile to PC via USB, I can not access files, it's not even detected. What to do?

Did you put it in USB mode?
Settings > Wireless and Network > USB Utils

More to the point did you read the manual and install Kies .

Thanks guys, both your advices helped. I'm new to Android and Samsung, that's why sometimes simply things for you are difficult for me.
Thanks again

Connection to PC
Strange is that I have the newest Kies but still I can connect GS2 only with Kies air. With USB cable the PC Win xp says that cant recognise the USB device. And through kies air I cant view folders and copy directly to them. Or is XP too old for samsung

I had problems with the drivers on W7 because I had an older version of KIES installed and when I installed KIES 2 it didn't work so I uninstalled everything related to KIES, reinstalled 2.xxx and now it works fine.

download mode -> unknown device

Hello everyone,
I've searched for a solution over the forum but I didn't find any solution..
So my problem is that I can't use Odin because windows doesn't recognize my phone on Download mode.
I have the drivers installed, Kies and windows recognize my GS2 without problems.
I've tried with different cable, different USB port, uninstall/reinstall drivers many times, from Kies or from samsung web site.
I just have no idea why in download mode windows doesn't use the installed drivers..
Help?
Thanks!
Did you try in a different PC?
I am sure driver is the only cause. Perhaps you can try following. Install Kies, then connect phone once and check if Kies detects your phone
Which version of Windows are you using? I am using Windows 7 and its working fine. I did root yesterday and Windows detected drivers and also it had to download from net for some reason. In the end it did work
USB cable to main board connection .
Reboot phone turn USB debugging off .
Set USB to Mass storage mode .
Connect cable and let Windows find USB drivers .

Did you terminate every Kies process before opening Odin?
Hello,
Thanks for the answers.
I'm running on windows 7 64. But it didn't try on another pc.
Windows does install drivers and recognize my phone in USB to Mass storage mode.
But still not recognize it in download mode and yes I've terminated every Kies process.
I know that in Download mode windows install some new/different (?) drivers. When I'm on download mode, windows fails to install driver as it's an "unknown device". Is there a way to install those drivers manually?
Hello,
Un-install Kies, reboot system, reinstall kies.
Still not work. After reboot and reinstalling Kies my phone was recognized, but in download mode there is still nothing.
If windows has USB drivers then download mode works .
Is USB debugging turned off .
Reboot phone
Enter download mode follow instructions on download mode screen .
Open Odin select files to flash
Connect Samsung USB cable to mainboard port .
Hit start on Odin .

USB debugging is off.
But as windows don't recognize the device, Odin can't detect it in download mode.
It's really weird

Ok, I manage to get this working.
I did this:
-I have unplugged all the USB on my motherboard, I've uninstalled all the "Universal Serial Bus controllers" (to acces type devmgmt.msc in windows start menu)
-Turn off the PC and unplugged the power supply. Waiting like 3 minutes.
-Replug the power supply and boot.
-Replug all my USB, windows reinstalling everything.
-Plug my phone in download mode and windows finally installed the drivers and Odin detect it !
So if someone have a unknown device issue with a code 43, please try this.
Thanks for your time and answers.
Disabling the "unknown device" and then disconnecting and reconnecting my phone worked for me.
Run Kies as Administrator, Install Drivers
This is what worked for me. Kies said the Drivers were installed without Administrator but nothing worked

Will not connect to PC

For some reason when i connect my GS2 to my computer (running xp) it wont give me the options to make it a mass storage device but when i use it on my laptop (running Windows 7) it works fine any ideas why and i ahve debugging on as well please help
you probably don't have the drivers installed on your PC - does the computer recognize the phone at all? if not, download samsung kies, and this should give you the appropriate drivers. alternatively, go on samsung's website and search for the appropriate drivers for the i777.
I'm having this similar issue but on Windows 7. I've already installed correct drivers and Samsung Kies. This issue began after I rooted my phone. I plug in my phone and my computer makes the device recognition sound. My phone is recognized in device manager as Samsung mobile usb composite device and my phone isn't in debug mode and doesn't give me the option for usb storage. I want to flash a rom into my phone but can't because I can't get into the internal sdcard. Any suggestions?
Try downloading pdanet on your computer. Then plug in your phone again. I had this problem and that fixed it for me.

yes, everything is ok but somehow my ( and other ) computer cannot detect the phone
You need to turn off the usb debugging if you want to connect the phone to the Kies on PC. If it won't connect, check if you have windows media player 11 installed? It looks like Kies uses something from that program - I was able to fix the connection by installing the WMP11 for XP...
I am using windows 7.
New issue, even when removing usb cable, the battery status is "Charging"
hmmm, USB completely not working anymore ( hard to charge, remove battery for some time then boot, USB only charging no MTP )

[Q] USB Not detected, wont mount

Phone: GTI9300
PC : WIndows XP
I have an SGS3 int'l version that has recently developed a USB issue after an unsuccessful attempt to update my firmware using Kies. Whenever the phone is plugged in via USB it will begin charging, but the PC doesnt recognize the phone at all. I have reinstalled kies with no luck.
Any ideas on the USB issue and how to possibly fix it?
Try reinstalling drivers.

I had same problem, and after 2 days to find a solution, i re-install win7 and it works directly
So you've got a problem with your win7.

Ya I did all that...now Im stumped..
When I connect the s3 to the pc, the phone immediately pops up "connected as a media device" , but the pc is not showing anything or picking anything up...
Try it on another computer (preferably Windows 7).
That'll allow you to see if the issue is on phone- or computer-side.
