[Q] Nexus S not detected by Computer

Just updated my phone (Nexus S) to cm-10.1-20121223-NIGHTLY-crespo. While it works fine as of now, one problem I am facing is when I connect it to the PC with the cable, though it goes into storage mode on the screen, however it does not show up in the PC. This prevents me from copying files from my computer to my phone.
It shows up in the device manager as a recognized Samsung device, but does not show in My Computer.......Any idea why this could be happenning ?
Thanks

I hope you have installed drivers and phone by USB direct to pc port not thru USB hub.
Happened to me once using USB hub cannot transfer files, so I connect direct and it works.

[Q] Nexus 5 not connecting to computer (usb), does not show in device manager

Hi,
I would like to see if I can get anyones assistance with solving my problem. I have lost the ability to connect my Nexus 5 to my computer via USB. I had previously been able to connect the phone without any problems.
Connecting my phone to PC charges the phone but no drivers are loaded, nothing changes in device manager and I cannot see a change in windows explorer to view the memory card.
So far I have tried the following:
searches on various sites
rebooting phone, starting in safe mode, wiping all data, performing a hard reset
connecting other phones to usb cable to check that it is not a charge only cable, also trying several other USB cables
connecting phone to other computers
connecting other phones (HTC) to load drivers (then uninstalling drivers)
displaying all hidden devices in device manager and removing all drivers that resemble something to do with mobile phones
uninstalling programs I no longer require on the PC
using "wugs nexus root toolkit" to uninstall and re-install drivers
checking & unchecking MTP, PTP, developer options, USB debugging in various combinations to elicit a response from the computer.
I have also tried to visually check the connections of the USB port on the phone wondering is there is a break but I cannot see very well.
does anyone have any further suggestions to get this phone connected to a PC?
my only last thought is to attempt to open the phone and check the resistance of the plug connections.

Have you tried enabling and disabling usb debugging while plugged in?

Are you sure you're using a data usb cable and the usb port is good?

Same Issue
same thing happened to me today when i connected the device to PC.
Mine says unknown device on PC under other devices. so i hope my USB port is ok.but im not using the original SUB cable. i wonder that's is the issue. but it didn't bother me until today. my original cable is at my friend's house.
Tried updating drivers manually. But following error message occurs once i select the drivers folder and hit ok.
Windows was unable to install your unknown device
Please help.

so, not really a solution but while at work my phone fell on to a nice rock cracking the screen. I have replaced the phone and the new phone connects to the pc fine, drivers come up without a problem (I will put this down to a fault with the phone)
Thank you for your assistance

sprint s5 ... cant access files on PC---help

I have a note 2 I currently use- when I plug the usb in - in windows 7 I get the option to view files etc....
I just bought a used sprint galaxy s5 from my ol ladys sister who had it hooked up at one of those corner wireless shops.
I want to root it but read to make sure your pc recognizes it first- which it does not.
Ive downloaded the latest usb drivers for the phone.
Ive enabled debugging mode.
Ive used the original supplied cord and also tried my note 2 cord.
When I plug it in it recognizes it and detects drivers but the phone does not show up under my computer and I dont get the window popup asking if I want to view files etc.
Getting really frustrated.
Any ideas?

When I plug the s5 into my pc and pull down the notification bar ...it doesnt even show usb connected.
I cant find any usb options other than usb debugging.
I just went through all this same crap with a galaxy mega a buddy had.
I just dont get why there is no "usb connected as" notification and why this is so complicated to connect to pc when my note connects fine

Bad cable? Maybe Bad Drivers? Where did you download them from? Windows is going to try to recognize it as a media device. Ill give you a couple tips
Just because the "popup window" doesnt popup, you probably just have auto play set to recognize it a certain way.
Just copy and paste this into your explorer window:
%windir%\system32\control.exe /name Microsoft.AutoPlay
and then reset it for your phone.
Also.
1. Make sure the cable is actually connecting, like charging the phone, consistantly, not on and off. If it is, then you know thats good, if not, switch the usb drive you have the cable plugged into. USB Ports actually on the motherboard are the ones Ive always had luck with never disconnecting.
2. If you want to root your phone, and you want the adb drivers, Windows wont find those for you.

Thanks for the reply.
I downloaded the drivers straight from the windows usb driver dowload page for my phone from samsung.
Ive uninstalled reboot,installed rebooted.
Ive set usb debugging off/on.
Tried dialling *#0808# which ive read is the code to enable usb but it doest work it just calls the #.
Tried all my moyherboard usb ports
Tried different cable
The original cable charges fine.
This sg5 NEVER has a usb icon when connected to usb... i find that odd.
A samsung mega a buddy had which was also previously hooked up at the same wireless shop that this s5 was..... also has the same exact issue.... no usb icon and not recognised as media by windows and no way to change usb settings.
Its like that wireless shop disabled usb on there phones for some reason.
I had the phone 2 weeks and cant do anything with it untill I can root it.
My note 2 works fine , i get usb icon in notification area,i can switch to media device from there.
On the sg5 theres no usb icon even though it connects fine to the pc as installer

Maybe Im misunderstanding you, but when I have my phone plugged into my pc there is no usb icon, its just connected as a media device and shows its charging. Both screenshots are of my phone while its plugged into my computer
When you plug it into your computer can you access the files on the phone through your windows explorer, like in the first screenshot?

Thanks for replying and the screenshots.
When my phone is plugged into the computer it shows the charging status but no "connected as media device" it doesnt show a connected as anything so nothing to touch for options.
The phone does not show up under windows explorer in my computer.
Ive been using galaxy phones since the original galaxy and never had issues like this.
I just dont get it

I'm similar issues...my phone will just time out in the middle of transfers or won't see the phone at all

Both of your issues sound like driver issues. Heres the link from Samsung for Windows for the S5
http://www.samsung.com/us/support/owners/product/SM-G900PZKASPR

To make this issue stranger....
My neighbor came over to borrow juice for her ecig. I noticed she has an s5.
I ask if i can connect it to my computer and as soon as I plug it in with my s5 cable...bam ...connected as media device , touch for usb options.
And my computer brought up the screen to view files.
So i now know its not my pc,drivers, or cables.
I did however notice when I plugged my s5 in.... in the notification area where it would say touch for usb options.
It says "system update"
But i have no sim or service on the phone so it doesnt update.
Could the system update be needed for the usb to work?
How would i even update system ?its nolonger on sprint. I wouldnt want any more over the air updates anyway as im wanted to root so i can save a straight talk apn and probablly flash a custom rom

Yea... this is nuts.
This sprint s5 i got looks and performs like a brand new phone.
But cannot for the life of me get "connected as ......" to show when a usb is plugged in. When i search settings for "pc connection" , "media" , mtp" , usb" etc.....
Theres nothing I can find to enable how to connect when usb is connected.
I dont even know who or where to ask anymore.
Bought this phone weeks ago and cant do anything with it.
My neighbors s5 connects to my pc no problems. So does my note 2.
I just dont know anymore what else to do

i dont see where not having a sim would matter. does the usb port on your phone seem loose or anything? do you have access to another pc to try connecting to that?
ultimately you can get around most things that require needing a usb connection. theres even a wireless adb.
i doubt this will work either, but have you tried seeing if odin will recognize the phone in download mode? (power off the phone and press the power+home+volume down buttons)
also what version of android is on the phone now? if its still on 4.4.2 or 4.4.4 then you might want to look into towelroot, but i think i remember reading thats not working with 5.0
as for rooting, you could try looking for a flashable update.zip , put it on a external sd card, put that in your phone and boot into recovery (power off the phone and press the power+home+volume up buttons) and flash it, then find a custom recovery like clockworkmod or philz touch or something
all in all im 99% sure theres a way to root the phone without having to do anything on a pc, its just a matter of finding a way to do it, and the before choosing a method to tell you to try, i need to know the android version. also im just assuming the model number is SM-G900P, is that right?
Go into your settings and tell me the
Software Version
Model Number
Android Version
and the Baseband Version

once factory reset...usb works fine.
Im now rooted and flashed MOAR
thanks for all who tried to help

Glad you got it figured out

Can't connect to PC for file Transfer

Brand New Unlocked S8+... Tried to connect it to my PC to use a previous copy of smart switch backup but it never connects.. Windows Explorer never displays a mounted drive either. Smart Switch Eventually comes back with Failed to connect to the device.
The Phone displays the "Attention The connected device is unable to access data pm this device. Reconnect the USB cable and try again...."
Phone is on Transfer Media files (MTP)
USB Debugging is one.
Device Manager says "Samsung Android Phone - SAMSUNG Android ADB Interface" two times - No red or yellow exclamations.
I've removed the software in device manager and restarted both the phone and the laptop multiple times.
I updated Smart Switch and did More\Reinstall Device Driver.
Does anyone else have any workarounds for this? I found one article (https://www.recovery-android.com/connect-samsung-to-computer.html) but still no success.
​

I actually have the exact same issue on windows 10. Anyone figured out a solution?

Doesn't seem like there is much help here on the 2 Samsung formums I posted on....
I know its not my windows profile as I have tried 3 different profiles as well as safe mode.
Tried 2 different sets of Samsung USB drivers and no improvement.
Like I said I had no issues on a windows XP machine or a windows 10. I didn't even need to install the USB drivers/Smartswitch on either of those machines.
We can't be the only 2 people!

Firstly, i cannot give you direct answers.
Just my thoughts.
i have a S8+. No root stock as is.
I have Lenovo laptop Win 10.
From day one, out of box, i connected
S8+ and it connected. I can do whatever
i want. Transfer data, photos videos.
ADB etc
So it should work...?
However i do realize there are quite a few things to consider......
Samsung drivers on laptop and a few other
issues..... eg
For one,
have you enabled
in Phone /Settings /Developers Option /Usb debugging.?
Normally first time when you connect
With pc /laptop you should get
a small pop-up message(on device) to allow
phone to connect.?
(that's my experience, over years)
Good luck

Yes, USB Debugging is on and connection is set to MTP.
Windows recognizes "USB Android" but dosnt install the driver successfully.
It will appear as a modem in Device manager but nothing is mountable.

I have 2 desktop pcs with win 10. One with samsung software Kies 3 and smart switch installed and the other no samsung software. Both find the device Galaxy S8+, in device manager under universal serial device controllers i have Samsung Mobile USB Composite Device. You have an adb driver I think because you have usb debugging on, i would turn usb debugging off. The pc should find a device connected to the usb and download a driver, once done the device is recognised as galaxy S8+ in my case but will not communicate with the pc until the phone has given permission. On the phone will be a message asking you to allow the connection. Hope this helps ??

Firstly i do understand that you
must be quite annoyed trying to figure
out issues. (I would) Thankfully i don't.
Bottom line is that it should work..!
My experience confirms, that S8+/laptop Win 10 works.... 100%when connected
However a few suggestions.
If you feel you checked all checkbox.?
However you never said anything
about popup notice ? granting premission
for device to connect.?
So device /laptop /pc is not "seeing" each other?
All Samsung devices I have used, first time connection gives me this popup a notice
Can't remember exact wording.
Something... eg
Device id 5786446.......
Have or does your other Samsung devices
connect etc.?
Have you tried connecting to a friend pc laptop.
An option is to go to a Samsung Care Center
and as them to test and connect.
My experience (in past) is that they should
assist you.
If it connects to friend pc or Service provider /Samsung Care Centre.
Then surely it has to be your pc/laptop?

So I turned off usb debugging and revoked the permissions on the phone, connected it to my PC.
Samsung Android (with a Yellow Exclamation) was already present in Device Manager under "other devices" so I uninstalled that.... and rescanned. My laptop attempted to reinstall but it generated a Driver Installation Failed message on "SAMSUNG_Android" - no driver found.
Device Manager once again shows the Yellow Exclamation Point

I would go on to Samsung support look up the phone and download the usb driver and install from the download. Good luck

I've downloaded the drivers from Samsung 2x.

I can vaguely remember that i had this same
issues with my Note 5 and Win 10.
This was many months/year or two, ago.
I also had yellow exclamation etc.
Further in Device manager( laptop) kept installing wrong Samsung drivers.!
I uninstalled drivers/installed and battle for a few months like this Then one day Windows
did an update and in update i noticed
Samsung drivers included etc. (must have been correct)
Ever since that update i had no issues again.
Bottom line... some drivers issue?
Not S8 +?
Good luck

In the past I had this problem I downloaded USBDeview to my PC and deleted all of the old Samsung drivers, after rebooting the PC the phone was able to connect with the PC.

Tried USBDeview and removing the Samsung drivers but no difference
Still unable to connect.

I'm having this problem as well. I'm still trying to work it out, but when I remove and re-add the device through Device Manager I get this error: "An existing device was found that is a duplicate of the device being manually installed" and the device DOES connect as a camera, just not for full file transfer.

I had the same problem and tried many of the fixes, including different USB cables and different computers and different phones. I finally figured out that the case I had on the S8+ was the problem (at least for me). I took it off and everything works.

Hi, i have a pc with windows 10 . In device manager under universal serial device controllers i have Samsung Mobile USB Composite Device. i think you should meet best mobile shop.

I have Windows on Lenovo Laptop with latest Windows updates installed. Yesterday, I downloaded Samsung Smart Switch unlocked the phone and connected it to the laptop. Smart Switch found it immediately and I did a backup. I did not need to check Device Manager. It must be a drivers problem as mentioned above.

Note 8, getting "Attention The connected device is unable to access data pm this device."
And I am only able to see some files, Sammy is a crazy fool, this is basic stuff

installed the windows fall update a week ago now connect my phone to my laptop and nothing is recognised, no phone memory and no memory card just a empty space when i click the icon where my phone should be, i've had samsung drivers installed and they have worked fine so far till today, any ideas where to find the latest drivers? and what else i can do to get access to my phone on my laptop?

solution that worked for me
On my windows 10 PC, I opened device manager (open up start and just type 'device manager') and under portable devices there was a usb device called MTP USB device or something like that (I forget the exact name) with a small triange and an exclamation mark next to it. I clicked on that and then clicked "update drivers." When the prompt comes up I chose the automatically look for drivers option. This fixed the issue and now my Galaxy s8 is recognized (it no longer says MTP USB device or whatever it was). Hopefully this works for others as well. You can also probably download the usb drivers for the phone from samsung.

PC won't recognize lg x venture for MTP or ADB?

Hello, I just purchased an LG X Venture, model number H700. It is running android 7.0. When I first got it a few days ago, I installed the drivers for it on my windows 7 computer, and plugged it in. I got a pop up on the phone where I set the default USB mode to MTP (media transfer protocol). It worked great, and I was able to tranfer files between my PC and my phone.
Then I tried to get adb debugging to work with my phone, and screwed everything up. I enabled developer options, and then checked USB debugging. I also accidentally hit the "revoke USB debugging authorization button." I installed what I think are the correct ADB drivers on my PC. Then I plugged my phone back into my PC. This time, nothing comes up. I've checked in the device manager, etc., and I can't find a trace of the phone anywhere.
I looked back at developer options under USB configuration, and it's still set to MTP. But somehow I screwed something up, because my phone and computer no longer recognize each other (except for charging).
I even tried my phone with two other computers (one also windows 7, the other mac), and got the same behavior.
Any idea how to fix this? Ideally I'd like to get ADB to work, but I would settle for just getting MTP back haha.

Actually, solved it! Turns out the cable I was using was damaged. I used another one and MTP works fine on all computers.
