[SOLVED] Phone Not Recognized by Computer

Hello everyone. My E4GT is unable to connect my computer after I install the drivers. I tried reinstalling them, used different usb ports, and different cables to find out that it still wouldn't work. The weird think is when I connect my phone to another computer after installing the drivers, it works. I'm hoping that someone knows of a fix to this.
OS: Windows XP SP3 32-bit
Edit: I solved this problem. What the problem was that I was missing usb.inf in WINDOWS/INF . To get this file, I got it from the other computer. At the time of me doing this, my only goal was to fix my webcam because I was getting an error about a missing .inf file.

Is your computer a "company" computer? Friend of mine had the same issue due to security settings on the laptop.

Try downloading the kies , sp?, program for your PC, it installs Samsung drivers and may solve the issue

Looks like you tried different USB cables (hopefully NEW ones), and different ports too. Along with Kies.
Try going into device manager (check show hidden devices too!) and uninstall ANY Samsung drivers or software you have installed. And reboot.
Download and install the latest drivers for the Epic 4GT [ http://org.downloadcenter.samsung.c...342248/Sprint_d710_USB_Driver_v1_3_2360_0.exe ]
Reboot your system. Then try to connect again.
If you have some type of Antivirus/Antispyware application you may also want to try and temporarily disable it too. I've seen this happen before.

I'm pretty sure it is not my antivirus because the other computer has the exact same antivirus. Also, in Device Manager, I enabled hidden devices and I do not see any drivers that seem like they have to do with Samsung.

Cool, but did you uninstall, reboot and then reinstall? And did you also disable the AV just in case?

Uninstalling Kies right now. I will post after I reboot my computer.

I rebooted my computer, installed the drivers, and it still did not work. It's like my computer does not know how to use the drivers for my phone.

Wow not sure what else to try. If you've tried removing all drivers and re-installing them, using brand new USB cable(s), using different USB ports and disabling AV software and if it does connect and show up on other PCs yet it still wont show on one PC, then something is amiss with that machine.
When you're connecting your device you do have it on too right? I'm sure you do but just checking.
Did you install any ROM on this device already? There are some international versions that if installed on this device disable the USB port.
And does it show up on other machines just not this one?
If it shows up on other machines than it there is something amok with that PC.
If it doesn't then..
One last thing you might want to attempt is to download sfhub's One-click FF18 http://forum.xda-developers.com/showthread.php?t=1721229 download the 'reset data' and extract the exe.
Make sure you phone is off and NOT attached to the PC.
Run the One-click application.
Simultaneously Press and Hold [Power] [VolDn] until confirmation screen appears
Press [VolUp] to enter Download mode
Then Attach your phone via USB to the PC and see if it shows up on a COM Port (anyone is OK).
IF it does you can then at least flash the stock rooted FF18 and get the device to probably work correctly next time you plug it in after of course the entire Odin/Update finishes and your phone restarts.
Just reaching here but hope that helps.

This shows up on other computers but not this one. I did install CM9 onto my phone, but when I was on stock, this problem was still happening. This is most likely something with this PC. Thanks for you help.

Well then that's it. PC is the issue it won't show. Something is pooped.
Good luck.

Just to be clear, when someone says, 'try different usb ports' make sure you only use the ports on the motherboard and not the ones on the front of the case or door.
It's the difference between powered and un powered.

Windows doesn't "see" note 2.

Good Evening folks,
I'm posting here after spending the better part of 2 days trying to figure out why this doesn't work.
So, i have the following:
model: GT-N7100
Version: 4.1.1
Build: JRo03C - ALJ1
I run a PC with windows 7 and also have a laptop with windows 8.
Now, initially i only wanted to root my device to install an addblocker on it and get rid of some bloatware. so i went and got samsung note2 toolkit here on XDA. (also tried others)
but no matter how i tried the pc (nor laptop) would see the note 2. it would plug in, it would charge... but windows ignored it otherwise.
i have tried al 8 of my USB ports on the desktop, and all 3 on the laptop. none of them work
3 different USB cables.
re-booted more then times then i can count.
i have manually installed the samsung drivers.
i have tried installing the windows MTP Porting kit
all to no avail.
So before i can even START to root... i need it to to play nice with my machines... anyone have ANY suggestions on what the hell is going on here.

What's the error message?

Happened to me before, un install kies on your pc reboot, download from Samsung website and install again, should work
Sent from my GT-N7100 using xda app-developers app

first of all I forgot to mention that this should've been posted in Q&A section
for the problem try the following steps. after each one of them try connecting again. keep net disconnected while you follow the steps.
if it starts working then stop other wise continue.
1)use a diff comp, but you already did that , use a different cable, you didn't mention it
2)try uninstalling drivers via programs and features.
3)try installing drivers - preferably via mskip's toolkit
if you have windows 7, then directly install it
if you have windows 8, then first disable driver signature enforcement via this guide's last question.
4)try re installing windows. if you don't wanna do that then
open device manager
in view -> show hidden devices
delete each one that says samsung, note ii or note 2, android, google, adb, gt-n7100, n7100
this will ensure that you truly remove drivers
follow step 3) after this.
Hope I helped

All the usual and helpful ideas have been listed and you should definitely work thru those to make sure you are not missing something obvious but critical. I also use Win8 (64) and all was well with my Note2 showing up as an MTP device and wll working then one day, seemingly spontaneously, it suddenly didnt! When I would plug my Note2 in, Windows would give me a USB error telling me it could nto recognise the device! To cut a long story short, I tried my wife's S2 and IT appered fine as an MTP device happily enough, so that ruled out the cable, the port and the computer/OS.
I then tried my Note2 on my laptop, and once again it came up as USB error, so the problem was following the DEVICE around....
After a lot of googling, I tried on thing that fixed it instantly:
On the phone, go into Settings, Security and delete all the "Device Administrators" which in my case was just my Email app. That did delete my email account from my phone (contacts, email etc) but didnt matter as phone is just a dumb client to the mail server so no loss of any real data.
Once removed, I then plugged phone in and BOOM! MTP device happily appeared! I then went back in and just re-added my email account and re-activated Device Administrator when asked. Working ever since.
Not saying this is your problem, but it was an eye opener to me that the Device Administrator could 'lock out' the USB connection of the device....
Hope this helps.

I would also recommend checking your Windows Update log - especially if you have it set to automatic updates. After I installed the drivers off of the Samsung website, Windows Update tried to "Update" my drivers to an older version (I do manual Windows Updates). The first time it asked, I let it, and my phone couldn't connect anymore. Once I stopped that silliness I stopped having problems.

I was having the same problem, but I was using a USB cord that I had from my old phone. Switched to the white one that came with my Note 2 and it started working.

Pratically given up on m8 with windows 8.1. What can I do?

I cant get adb drivers to work with 8.1. I've tried every driver in the book. Followed a few guides , erased drivers , reinstalled , even at one point tried reinstalling windows , different USB port, different cable . now I am no means a novice , but is there something simple I'm missing ? Any help appreciated

perhaps uncheck mtp and select camera and turn off debugging ? boot into recovery while connected ? that installs a driver also. have you installed a "naked driver " ?

Need more info about your problem. what happens when you type adb devices?

If I'm not mistaken there were a few people that had the same issue and it turned out to be a bug when trying to use a USB 3.0 port on their computers. If you are using a USB 3.0 port for your cable you might wanna try plugging it into a USB 2.0. FYI I could be remembering completely wrong

I did everything but an engineering hboot with USB 2.0 port on an Intel x79 chipset motherboard on Windows 8.1.

I had this problem too but got around it. I had no problem getting the device detected in Fastboot mode, but ADB was a problem. What I did was download and begin installation of the latest HTC sync manager with the phone already connected. It seems the first thing it does is install updated drivers then asks if you want to continue with the installation. I didn't want to install sync manager, so I cancelled the install. However the drivers remained. After a reboot I checked Device manager and sure enough Android 1.0 device was there with working drivers.
Checked the device was recognised with the ADB command ADB DEVICES, but showed no device connected. I then unplugged the USB cable and plugged in to another USB 2.0 port and voila device gets deteced by ADB.
I also had to use this version of ADB http://www.mediafire.com/download/e5mieo2vxjd71ws/android-tools.zip and it had to be the original HTC USB cable and USB debugging enabled in Developer options.
Now for some reason I have to swap USB ports each time ADB doesn't detect the device and pretty much works each time.

I think it's usb3 issue , adb doesn't work on usb3 ports,
there was a subject on how to convert usb3 port into usb2 search the forums

USB 3.0 worked fine for me on 8.1. I used Sooner ADB drivers and manually picked them.

I have no issues on win 8.1 I use the Google USB drivers that are with the sdk. The first time, I do have to go into device manager and update the driver. When it asks do you want to locate the driver or pick it from a list select pick from a list. There should be an Android entry if you installed the USB driver. Select that and then select adb interface. You'll also have to do the same for fastboot mode the first time.

I couldn't find a working version of ADB for 8.1 however I installed HTC Sync from the virtual CD and that installed all the drivers. Uninstalled sync manager cos I don't use it and the drivers remain and work fine.

check your usb 3 controller. Is it intel 3.0 usb controller. if you see intel xtensible controller in device manager this could be the issue, it can break adb on all ports. here is a link to a fix for this usb problem i can confirm it works as i have had this issue myself. Hope this helps

search for all-in-one-toolkit for the M8. it has links to installing drivers, u can use that toolkit to flash RUU, kernel, recovery, unlock bootloader and even run commands.

No USB detection in Windows

I was having an issue with my i9250, my phone would not be recognised in windows when switched on normally, so I replaced the USB flex inside,and I'm still having the same problem.
My computer will detect my phone in fastboot mode, or in odin mode, but I will not be detected normally, nothing appears, not even unknown device, and I have enabled usb debugging, flashed mutiple stock images but I still have the same problem, have you got any more ideas for me?
Thanks.

what windows you using? did you enable usb conection on phone? if you are on windwos 8 look at softwere update to install new usb driver for our phone

Make sure you have the right drivers installed. There is a stickied thread that contains all the steps of returning to stock 4.3. I believe the first step deals with getting the right drivers and installing them correctly. I would suggest following those steps.

Connect phone in usb debugging mode and then Try to manually install the drivers from device manager.

[A] USB Device Not Recognized

Hey Guys,
So im having an issue for when i try to connect my note 2 running Jedi X20 to my windows 8.1 computer i get an error stating "USB Device Not Recognized". I have tried everything from trying different cables, downloading drivers, deleted and reinstalling drivers, checking to see if my phone is set to PDA, trying factory reset in TWRP, etc. i was wondering if anyone has successfully fixed this issue and they could help me.
I am trying to get my device connected so ODIN may recognize my device so i can revert it back to Stock.

My note 2 is also showing up as "unknown USB Device (Device Descriptor Request Failed)

Have you tried the USB ports on the back of the PC? If so....
Maybe try updating the drivers for the motherboard of your PC instead of using standard Windows 8.1 drivers. Assuming Windows 8.1 is recognizing all the USB ports you are trying to plug your cable into.
If this does not work and you have a copy of Windows 7, download Virtualbox and install Windows 7 as a virtual machine. Launch it make sure you have the USB settings inside the virtual machine setup to allow the USB to be used from Host PC.
Load the Samsung drivers in the Windows 7 virtual machine. I'm assuming those are the drivers you have stated you have downloading and reinstalled.

Sorry meant to say it's a laptop. Tried all ports and installing drivers. Unfortunately I don't have windows 7
