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.

[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

[Q] "Device unplugged" during installation of drivers

My problem is the following:
I decided to flash a custom rom on my HTC HD7, and started by connecting the phone to my computer (Win 7, 32bit) via USB while in Bootloader. The phone is recognized as "Qualcomm CDMA Technologies MSM" (HTC USB Sync) and the drivers installs correctly, but when I try to install drivers for the "Unidentified device" with WMDC the installation starts and ends shortly there after with the message "Device unplugged" and a message that the drivers weren't installed.
In device manager I can see the "Qualcomm device" but there is no sign of the phone (supposed to show as "Schubert" if I've understood correctly) or any unknown device. I've also tried this on another laptop with same OS but I get the same messages and no sign of the phone in device manager.
Does anyone have an idea of what's wrong?

You have to install " Mobile device center" in your computer before installing drivers
regards

I've installed WMDC but when i connect my phone there is no sign of it in Device Manager or any drivers being installed, only "Qualcomm CDMA Technologies MSM", and WMDC shows no connected device. The bootloader on the phone tells me that the phone is connected with USB, but my PC doesn't
show any sign of it.

Fastboot USB error: A request for the USB BOS descriptor failed

Hello all,
I got an old 5830 Galaxy Ace I wanna hand over to a friend. I want to flash stock ROM onto it.
When I start the phone normally I can connect via USB cable and see the files on the device.
However when entering 'downloading' mode (power+volume down+home) I get the error: This device cannot start. (Code 10) "A request for the USB BOS descriptor failed." (copied from Device Manager properties of Samsung USB Composite Device). I also see this ballon pop in in the sys tray
The device does NOT show up in either Odin or Flashtool.
I am on Win 8.1 64bit laptop. I have searched and trawled the internet already and did the following:
- disabled signature verification in startup options of windows
- installed fastboot drivers via flashtool
- installed Samsung USB drivers
- tried 4 different USB ports and two different cables (and also on another laptop)
Can anyone give me a suggestion. I have not found 5830 specific USB drivers for example (nor do I know if they even exist). Any help is appreciated!
Regards,
Roel

SOLVED...sort of...
I used a workaround. I used a Windows 7 computer and there it worked perfect.

I have this problem all the time. I only have a work around. Eventually it always comes back. Anyway, in device manager I select update driver, browse my computer for driver, let me pick from a list, scroll to portable devices , click next, choose MTP USB Device

I have done it before doing the https://www.tenforums.com/drivers-ha...ows-10-pc.html it was not working but now it shows the R1 HD
Thank you
