[Completed] [Q] LG G2 PC doesn't detect USB connection - XDA Assist

I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB icon on android system tray) even with "Ask upon connection option checked".
I have tried downloading Drivers for the G2 but still it didn't work.
And no computer seems to detect it.
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definitely there seems to be a problem with the phone, but I don't believe it's a software but a firmware problem.
Please help if anyone knows what to do.
(I've already posted a similar thread, but I've forgotten to check it and it's closed now. Sorry for about that)

One more USB question...

Hi there...
A quick question about the USB...
Is is at all possible to have a USB-port that can still charge the phone, but at the same time is "dead" when you try to connect the phone to the computer ??
I have also asked about it here:
http://forum.xda-developers.com/showthread.php?t=1179171
The story is that the Phone (SonyEricsson X10i) can be charged fine, but when i connect it to the computer, my computer say that the hardware is not recognized, nomatter if it is in flash-mode, mounted from recovery or in the normal way.
And the phone don´t even show anything about USB connection in the status bar eigther.
I have tried 5 different computers now, and 2 different usb cables.
I have also a X10 mini and a Desire HD that works fine on all the computers and both cables.
I have tried to remove software, remove drivers, clean computers, reboot, check the memory-card in the phone, install software and drivers and all other things i can think off...
It is two windows 7 and three windows XP computers btw.
So is it at all possible that the phone can still be charged, but data-connection fail ?
As i see it, there must be some kind of data-exchange or else the computers would not even say "hardware not recognized"...?!?
I'm not quite sure I understood your question correctly, but let's see if this helps:
I used to have phone that didn't have drivers for Windows I used at the time (I think it was Windows 7). That meant that Windows wouldn't recognize it (when plugged via USB cable) and will not therefore provide power to that USB port (hence the phone will not charge).
I was able to get around the problem by going to the device manager, locating the relevant "unknown device" and force installing some random drivers for it -- I don't even remember what it was that I picked -- something that Windows would allow me to do. Of course the port wouldn't work as a data connection like this, but since Windows now 'knew' the device, it powered the USB port and I was able to charge my phone from it.
My problem is that I actually can charge the phone ok...
But I am not able to make a data connection between the computer and the phone at all...
My question is then, if the usb connector in my phone can somehow be broken even though I am still able to charge the phone...?

I'm fairly sure that yes, the contacts or the controller can be broken so that you can still charge but be unable to establish data connection.

[Q] Windows 8.1 connection issue

Hello everyone.
I am having issues with my Note being detected by my PC, I have installed Kies 3 and when the Note is connected the connection process starts but fails ( I tried using camera mode instead of MTP and Kies says It must be MTP so something is connecting), Also the device is detected in the device manager of the PC and the Note itself says its connected by USB 3.0.
I have updated, un-installed re-installed, all the drivers and Kies. I have also used a standar USB 2 cable and most of the ports on my PC.
Does anyone know what's going on? could it be a USB 3 issue with Windows?
Any help would be appreciated.
Cheers

I've been having consistent issues connecting with the tablet through adb, on both linux (2 separate installs), and windows 8.1. Sometimes it just will not detect it. It gets detected as mtp storage fine, but adb devices returns nothing. Ill triple check all the relevant settings, make sure the computer has been authorized by the tablet etc. It will literally work just fine, and then 10 minutes later without even disconnecting the cable to using the tablet, it will no longer be detectable by adb.
I'm hoping it's just bugs in the release firmware that haven't been ironed out yet, and will disappear with future upgrades or with the flashing of a custom rom.
I've also had it refuse to charge through my laptops USB ports, even the special "faster charging" port.
It turns out my issue was the unit itself I took it back to JB-HiFi and the staff checked it out and it wouldn't connect to any of their PCs, we tried the Demo unit and it worked fine, So i exchanged it and it works perfectly..
Thanks for your reply though
Cheers

[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

[Completed] Old Cricket Flip Phone USB issue.

So basically I have an old Cricket Flip Phone from 2009 which has pictures on it which I would like to move to my PC. The info on the phone itself is "www[DOT]phonescoop[DOT]com/phones/phone.php?p=2217". My issue with the phone is that I cannot get it to detect on either my Windows 8.1 or Windows 7 PC. The USB cable definitely works because it does provide a charge for the phone. When I connect the phone to the PC in the Device Manager I do see a new device under "Other Devices" which is named "Qualcomm". I have googled around and found two (not sure if official) drivers. However I can't get them to install. I did see a thread on this website regarding some Qualcomm drivers but for whatever reason it was not allowing it to be trusted. And when I try to update the driver through "My Devices" it just says "Windows could not find drivers for that device". There are no USB options on this phone.
Does anyone have any input on where I can find the correct Qualcomm driver I need for this phone? I would greatly appreciate it.

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.
