USB Device not recognized

I've searched and tried everything I found but my phone just can't be read as a Mass Storage Device....which means I can't transfer any files.
When I plug the phone in the USB debugging icon shows up on the phone but the option to transfer files isn't there. And on the computer it says USB Device not recognized and it's listed as an Unknown Device.
What I've tried so far is uninstalling the driver completely and plugging the phone back in....some sort of software automatically installs itself whenever I do this. However it still doesn't fix the problem. Also, I've downloaded some drivers from the internet but when I try to "Install driver from specific location" and direct it to the folder, it says there was no updated drivers found.

can we use it as usb mass storage?

Was wondering is there a way to use our galaxy as a universal usb mass storage device, using default windows drivers?
I've tried it but I can't seem to connect my phone to the pc unless I install either the usb drivers (extracted from Kies) or install kies itself.
In ubuntu can just hook this up no problem why in windows doesn't it work? or am I doing something wrong? Any help would be great.
thanks.

Wich part of Android Development Forum you dont understand?

why don't you can suggest me one or point me in the right direction or notify a mod instead of posting something that's not helpful and insulting?
and indicate why this would not go in development? yeah it can be in general but why can't it be in here explain the reason. This can be the initiation of someone developing a hack to allow to use our device in windows without INSTALLING the samsung drivers?

You don't need to install any samsung anything.
Settings -> About Phone -> USB Settings: Ensure "Ask on connection" is selected.
Plug in USB cable, connect to PC.
Select "Mass storage" on the menu. Your device is now connected and charging, but you don't have access to the data yet.
Now drag down the notification bar from the top of the screen. It says "Ongoing: USB connected. Select to copy files to/from your computer". Press that. Press "Mount".
Your Internal SD and external SD now mount on your PC and appear as drives.

Edit: If that doesn't work for you then there's something wrong. I haven't installed Kies on any machine I've connected the SGS to. It may be that you require Admin rights to install the usb drivers that are sent over as the device attempts to mount (not sure).

hmm that's weird. My machine says it doesn't recognize it when I do that. And all the machines I use I have to install the drivers for it to work even though I always use "use as mass storage"
hmmm I better do more investigation then.....

just tried this on a winxp machine without any driver/kies installed and yeah can't get to the sd card. It has an exclaimation mark next to the Usb mass storage device in device manager and there an "unknown" device detected in the "other devices" section of device manager....

Try the always ask option. Sometimes the use mass storage as default choice is a tad cranky.
If not, try on another usb port with another microusb cable. I've tried on 3 pcs/laptops and all 3 times no drivers were needed.

You also have to pull down the notifcation menu of the phone (once connected) and click the usb symbol and then choose "mount" (yeah, kinda sucks)

the drive that it installs when you connect your device to your PC with selecting USB Mass Storage is a normal USB driver, like when you plug in a normal memory stick...

Check your usb port or cable and try other ones

Or install Kies then uninstall it.
It will leave the Samsung USB drivers installed as they are in a seperate folder.

really weird could it be a winxp problem?
At work usb mass storage doesn't work UNTIL I install the samsung drivers. At home tested on a win 7 machine without installing any drivers and it works.
Would front usb port be different to teh back usb port? It's just that front usb port doesn't work if I don't install drivers, after install drivers works fine.
hmm I should test the back usb port. It's pissing me off how I can't use usb mass storage at work until I install the drivers (or would it be a windows update issue how windows don't have latest usb drivers?)

both win7 and xp require to install that usb driver unless you've plugged it in before... you definitely don't have to install the samsung drivers before you use the Mass storage function as my office computer (XP) is not allowed to install any other driver/software apart from normal USB mass storage driver in which it's pre-installed in your PC when you install the OS...

PC not recognizing Captivate after Root

Hi,
I have rooted my Captivate and now I cant get the device to be recognized in windows 7 (64-bit)
I have tried installing the "SGH-i897_Captivate_USB_Drivers_5_02_0_2" drivers for Win 7 (64-bit); enabled USB debugging on the phone and also selected USB Connected menu to copy files from/to the computer. The PC is able to recognize that a USB device is plugged in but detects it as a Unknown device.
When I manually attempt to install the drivers from device manager, it detects the device as for "Samsung Android USB Composite Device" but ends up saying that the device cannot be started (Code 10).
I have also tried plugging it into a different USB port just to check off a problem with the port.
Appreciate any pointers regarding this.
Thanks

Issue exists with WinXP
Update: I just tried the same on my WinXP (32bit) laptop and still the same issue. This is driving me nuts!

Check the port on your phone and make sure your cable is fully seated. I had an issue once with mine doing the same thing but it was just my cable getting caught on the little slide protector.
Sent from my SAMSUNG-SGH-I897 using XDA App

I did move it to a different port and also as I mentioned above tried it on a different PC. Both have the same problem.

Have you tried the galaxyS drivers?
Grr I cant put links in here for the wiki where its locked.

I installed the "usb_drivers_GalaxyS_x64" drivers and plugged in the phone. It recognized the device correctly and I am able to see the phone in Explorer. I didnt have to enable USB debugging as well.
Thanks for help.

Glad it worked. Watch out for the keys program as well. It we over write the drivers with ones that dont work.

[Q] USB Debugging/Mass Storage Mode connection to computer issue

Hello folks,
I'm facing this "please insert a disk" issue when connecting my Note to computer via USB Debugging mode / Mass Storage Mode.
I'll let screenshots in the attachment explain itself. #1 shows the screenshot of devices menu when the phone is plugged into the computer in DEBUG mode; #2 shows the screen after I've clicked "connect USB storage" from the drop-down list of the phone; #3 shows what happens when I try to open one of the two "removable disks".
MTP mode works fine, as well as Kies connection. As I finally started exploring the potential of Android platform, I realized that MTP and Kies connection are the most useless connection options for me, and I'd rather leave it in debug mode all day. So has anybody experienced this issue, or had any suggestion on the solution?
As always, many thanks in advance, and many thanks button clicks afterward!
p.s.,
Desktop OS: Win7 Pro X64 SP1
Note: 2.3.6 Stock LB1 Open Germany Firmware, CF rooted LB1 kernel.
Also, I should have all the latest official device driver from Samsung, as I have the latest version of Kies installed (and I discovered a driver folder under Kies' installed location). I'm not so sure about adb driver, but I was able to find the Note to be listed under devices by typing "adb devices". So.. I don't know where could've gone wrong.

Help anyone?

This really sounds weird... I was facing problems of the Galaxy Note not being detected on several Windows7 32/64-Bit SP1 computers as well but this was gone after I installed SAMSUNG_USB_Driver_for_Mobile_Phones.
You are right - from all that i know all required drivers should be available when KIES is installed on your system. Whatis even more strange is that your device seems to be detected as two partitions are available and are displayed in Explorer...
So I would test the following:
- check if your device manager lists any unknown devices
- Uninstall KIES and try to find the SAMSUNG_USB_Driver_for_Mobile_Phones and install those
- check all available USB ports and see if this solves the problem
- try another USB cable
- make sure your (external) SD card is formatted with a Windows compatible file-system e.g. FAT32
Hope this is helpful and helps solving your problem.

Thanks for your reply!
My device manager basically listed all the drivers/devices associated with the phone:
My Device manager shows devices:
Samsung Android Composite ADB interface
Android UMS Composite USB device (x2)
SAMSUNG Android USB Modem
USB Mass Storage Device
USB Mass Storage Device (Android)
I've attached the screenshot when all the drivers being installed when the phone is firstly connected to the computer. Also in the device manager, everything shows "this device is working properly"
I then decided to test with another Note of my friend's (On the same computer). Her Note has no SD card in it, and is completely stock ROM non-rooted LA4 Open Germany firmware. The same thing happened.
One thing worth mentioning: Yesterday, this worked only for once. When I initially encountered this issue, I restarted my computer, and boom, my phone was connected in Debugging mode! However, once disconnected, and I tried to connect it to the computer again, this issue came back. And afterward, no matter how I restart my computer, the phone won't get connected.
I also tried all USB port (USB 2.0 and 3.0), three different cables (2 of them are Samsung OEMs) and failed to address the issue.
I'm nearly exhausted but I will never give up, as this is my only computer and my only phone (haha), and without solving this issue, I'm never gonna be able to view the phone as a USB storage and easily transfer the file from my computer to the phone.
I'm going to try the last thing that I haven't done from the list you posted:
- Uninstall KIES and try to find the SAMSUNG_USB_Driver_for_Mobile_Phones and install those
I believe that I can keep the driver folder in the Kies' folder, as I believe those are the newest Samsung driver, given that the Kies was the latest release version.
So far, I can only conclude that this issue is not related to specific phone but the Windows 7.
And thank you for your help btotaku!
If anyone has any insight into this issue, please help me. Thumbs up for you!

BTW, I was able to extract both SAMSUNG_USB_Driver_for_Mobile_Phones.exe from under Kies' installation path under Program Files x86 folder, and an uncompressed folder of all kinds of drivers for Samsung device, called "USB Drivers".
And looks like I was wrong. The newest version of SAMSUNG_USB_Driver_for_Mobile_Phones I had was 1.4.8. While the driver that came with the newest Kies was 1.4.103
I'll post back soon

Reinstal Windows on your PC bro.
Problem fixed.

is that your internal memory or the sd card?

Same thing happens either with SD card in the phone or not

Device Won't Connect to PC

For the past week I've been trying solution after solution found from the net to try and get my HTC One to connect to my computer and show up as a portable device. I'm running Windows 7 x64 SP1 with all updates possible, latest drivers and chipset drivers and even installed optional drivers to try and fix the problem. I've tried USB Debugging and nothing happens, tried uninstalling all drivers from USB device manager and reinstalling which also didn't work, tried installing MTP drivers seperatly, nothing happens, tried windows update's htc drivers, they fail to install every time.
My problem in short is, I cannot get my device to connect to the computer so I can use the storage space to add/remove/edit files on my phone.
I've recently tried a program called "DoubleTwist" which actually got the HTC Sync Manager to recognise my phone, but even that shows no storage available.
My details:
Windows 7 SP1 x64 PC,
HTC One in metallic blue 32GB,
HTC MTP Device Drivers Failed
MTP USB Device Drivers Failed x3
Developer unlocked,
USB Debugging On/Off
I can edit in any additional details required.

Umh, connect the phone at the pc, go to Device Manager (windows logo + x -> device manager), and unistall all the voice about the one.
After go to the control panel, and unistall the htc driver from here.
Now, install HTC sync.
For me and other friend worked.

I've tried uninstalling the failed drivers but they still fail every time i plug the device in, It's not really a problem with htc sync manager as I've pretty much given up on that already. My problem is that I can't get my computer to recognize my device, only as a cd drive which is for the installation of htc sync manager and and relevant drivers.
I've tried your solution 5 times before and it doesn't fix the issue as it's the drivers failing to install and the fact it won't accept drivers for my usb device for MTP or pretty much anything related to my device.
Anyone know of away to remove the bad drivers and install fresh working ones without crippling the use of my mouse and keyboard? because windows suggests I remove the usb host controller drivers which kills the use of all usb ports on my computer, meaning i have to replug them in turn re-installing the usb host controller drivers at the same time.
still got the problem of not being able to connect my device and have it recognized, by the computer as mass storage, removable storage, or MTP. that is the real problem I'm trying to fix, after that I may consider trying to get htc sync manager to work.

Any help at all would be nice... Anyone?

I guess my problem is unfix-able then, just to make it clear, i don't give a stuff about the sync manager, i just want to be able to have my computer recognize my phone so i can access it through my computer...

Got the exact same problem, work PC won't recognise the device. Haven't tried home just yet as this is the first it has occurred. Software update a couple days ago.
Called HTC - no dice, they keep saying install HTC Sync and the drivers.
Anyone else come across this issue/have a solution?

I posted in a different thread, but let me sum up again.
I had a couple of people reporting this issue on Win7 - phone connected to USB, came up as android device with exclamation mark in Device Manager. It really made me think what could have happened, because it was working a week before. I tried different cable, different drivers and realized it was something wrong, when even my phone was not recognized on my friend's PC, yet both of the phones (mine & his) were recognized on my notebook with all the cables and config.
It turned out, that he installed malware stuff and the culprit was iLivid and his friends. It blocked the usb connection somehow. After running Malwarebytes in safe mode, which removed a tons of sh*t, everything worked again.
