[need help] usb device not recognized!!!

hey guys,
I don't know if this still a problem with people. but I'm on win7 64bit and I can't seem to connect my nexus s, to my computer. I always have to upload from computer to dropbox then download the file from DB on my phone... usb plug doesn't work. I tried the same cable with my wifes Samsung vibrant and it recognizes it, but when i plug in my nexus s the debug icon shows up on my phones status bar for like 1 second and disappears. then window on my compter says "USB Device Not Recognized"
need help please.

What does it say in device manager (in windows)? Maybe the driver is wrong...

do u have a right drivers installed
have a look here and check Google USB Driver

I'm having the same problem. I have tried both my computers and multiple cables but I continue to get the error. When I try to update the drivers or reinstall them Windows says the drivers are up to date. I've tried every USB port on both computers as well.
I even took the phone into a repair place to see if perhaps the USB port on the phone was malfunctioning and they couldn't find anything wrong with it.

Try installing pdanet, I had a similar issue when I rooted my ns and installing the pdanet drivers solved the problem.

I've been having the problem also and none of the fixes worked. Not even PDA net. You'd think that the more people have this problem so one would have found a real fix by now.

I can't get the PDAnet drivers to install - during the installation process, my phone has to plugged in, which of course the installation program can't see.
Weird thing is if I remove the battery and then plug the usb in and start the phone, the drivers show up in the device manager but they always disappear before I can unlock the phone - appears the USB connection on my Nexus S is broken...can;t think of anything else.

[Q] Computer not recognizing phone when in USB Debugging Mode

I am trying to install the ADB drivers but my phone is not appearing in the device manager at all for some reason. I have USB Debugging mode turned on but all that pops up when I plug my phone in is the auto play that asks me if I want to open the device to view files. I have no android device listed in my device manager to install drivers to. I have tried on two different computers and my phone is not recognized.
I have the google edition on 4.3

have you tried a different usb cable?

Uninstall and then reinstall Kies and try again bro, that should work bro.

Try a different cable. Had an issue was GNex where it charged fine, connected to the computer okay, but couldn't get adb or use odin. Spent hours trying to figure it out, uninstslling, reinstalling, and rebooting everything under the sun. Then thought maybe, just maybe it might be the cable. Swapped it out, and it worked like a charm.

[Q] PC/Laptop No Longer Recognizes S4

The device is stock. I am using the stock USB cable and have tried both my PC and Laptop to no avail. I have tried installing the USB drivers from samsung.com, updating Kies and everything. I have tried every single USB port on my PC and on my Laptop, none have worked. It sometimes says the driver has been successfully installed, but then Kies says I should try Kies 3 which then says its an unsupported device. I am so stuck. Thanks for your help.

If you can live without kies uninstall it. It'll interfere with your usb drivers.

Go into device manager, view, show hidden devices. Then delete all the usb devices that are greyed out. This is kind of a pita. Then reboot your pc, then let it find your device by plugging in the usb cable.

Rebooted. Still nothing.

Get a new quality cable.
Does the USB icon appear at top of phone. If so, pull down menu and tap on the usb listing and select a different connection and see if that works, like camera etc.
It could be a hardware issue. Take it to a store.
Is USB Debugging selected on phone?
You could after all else fails, Use a wireless app to back up personal phone data and do a factory reset. Even using MyBackUP pro and putting backup on ext sdcard.
Maybe even pull sdcard and pull battery and reinsert/rebooot with no sdcard.
Kinda grasping on some of these ideas--

One last thought. Are the usb ports 2.0 and not 3.0? 3.0 don't work.

good point jd, forgot that one
also some talk of taking the 4.3 update causing usb issues--only 2 pages, scan thru it--:good:

Reinstall ubs host driver (Not the cellphone one)
Use another cable.
Put your Phone in MTP mode in the options above when asking just charge or transfer pictures MTP or Mass Storage.

Tap on the "Charging mode" notification when your USB is connected and you'll get a pop-up that let's you select MTP mode.
Alternatively you can go to Device Manager and look for any error icons (think they're yellow triangles - been a while since I used a PC). Right click and uninstall all the offending ones, the disconnect and reconnect your device via USB.

In a lot of MM roms, you have to go in to developer options and select MTP under 'MTP configuration' in there. Even if it's selected already, tap it again and it should pop up asking what to do when device is connected on the pc. $5 says that does the trick. Easy but surprisingly tough one. One other problem I'm running into lately with the new windows 10 is that it has driver signing enabled by default and often rejects the driver you install or just doesn't use it even if it's installed. So if the driver is the problem (or more accurately windows 10 is refusing to acknowledge the installed driver), you might need to disable driver signing enforcement. Here's a link how to do that: http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/

Weren't you having quick charge problems too? Is it possible your phone's USB port has a hardware problem?

Did you ever flash the stock factory images?
Guess you can't if the comp doesn't recognize

I did flash stock mm and that's when this started happening, I flashed stock mm because I was having issues with turbo charge on a ROM I was using. But flashing back to stock mm didn't help and now I can't even connect my phone to my PC..

Pc not detecting android but charging

Hi Basically plugged my S4 i9505 in via usb. Nothing shows in my computer, but phone remains charging. I have tried uninstalling and reinstalling all samsung usb drivers but it does nothing. Tried installing kies/older usb drivers, still no luck. Regardless of if there are drivers or not on my pc, there is no detection what so ever. My pc is detecting my second S4 I9505 perfectly. Anyone know the solution to this?

Tap 5 times buildnumber in settings menu under: about phone to open developer settings. Enable USB debugging. Now you can choose what to do when phone is plugged in pc.

USB debugging is Enable still nothing happen

USB debugging is not required in order to have the phone recognized by the computer.
Have you tried different USB cables and USB ports? Is the phone detected on other computers?

i had the same problem.... and we found out that the pins or the usb connection sh1t from the phone doesn`t make good contact. si try to push a little but or force up and down the usb cable to the usb from phone maybe you will manage to find a stable connection or something.
when i connect to phone to the pc i have to hold the usb cable connected to the phone in a weird position. that works for me
