download mode -> unknown device

Hello everyone,
I've searched for a solution over the forum but I didn't find any solution..
So my problem is that I can't use Odin because windows doesn't recognize my phone on Download mode.
I have the drivers installed, Kies and windows recognize my GS2 without problems.
I've tried with different cable, different USB port, uninstall/reinstall drivers many times, from Kies or from samsung web site.
I just have no idea why in download mode windows doesn't use the installed drivers..
Help?
Thanks!
Did you try in a different PC?
I am sure driver is the only cause. Perhaps you can try following. Install Kies, then connect phone once and check if Kies detects your phone
Which version of Windows are you using? I am using Windows 7 and its working fine. I did root yesterday and Windows detected drivers and also it had to download from net for some reason. In the end it did work
USB cable to main board connection .
Reboot phone turn USB debugging off .
Set USB to Mass storage mode .
Connect cable and let Windows find USB drivers .

Did you terminate every Kies process before opening Odin?
Hello,
Thanks for the answers.
I'm running on windows 7 64. But it didn't try on another pc.
Windows does install drivers and recognize my phone in USB to Mass storage mode.
But still not recognize it in download mode and yes I've terminated every Kies process.
I know that in Download mode windows install some new/different (?) drivers. When I'm on download mode, windows fails to install driver as it's an "unknown device". Is there a way to install those drivers manually?
Hello,
Un-install Kies, reboot system, reinstall kies.
Still not work. After reboot and reinstalling Kies my phone was recognized, but in download mode there is still nothing.
If windows has USB drivers then download mode works .
Is USB debugging turned off .
Reboot phone
Enter download mode follow instructions on download mode screen .
Open Odin select files to flash
Connect Samsung USB cable to mainboard port .
Hit start on Odin .
jje
USB debugging is off.
But as windows don't recognize the device, Odin can't detect it in download mode.
It's really weird

Ok, I manage to get this working.
I did this:
-I have unplugged all the USB on my motherboard, I've uninstalled all the "Universal Serial Bus controllers" (to acces type devmgmt.msc in windows start menu)
-Turn off the PC and unplugged the power supply. Waiting like 3 minutes.
-Replug the power supply and boot.
-Replug all my USB, windows reinstalling everything.
-Plug my phone in download mode and windows finally installed the drivers and Odin detect it !
So if someone have a unknown device issue with a code 43, please try this.
Thanks for your time and answers.
Disabling the "unknown device" and then disconnecting and reconnecting my phone worked for me.
Run Kies as Administrator, Install Drivers
This is what worked for me. Kies said the Drivers were installed without Administrator but nothing worked

the guy i bought it from told me the phone was rooted before but he restord it before he sold it to me. eany ways i have try all the USB ports in my pc
and have try 2 diferent pc too, tried diferent cablesn and i have install the drivers in all of the other computers. i put it on debuging mode and the computer simply doesent recognise it. i tryUSBDeview and i dont see samsung drivers eanywhere but i know i have them install in fact i have re enstalled them and nothing

eany help will be apreciated thanks
Download Samsung kies. It will install Samsung drivers for you.

Sent from my SGH-T959 (Samsung Vibrant)
I have tried that and nothing :/
Try turning USB debugging off and try again...
By the way, you're on stock 2.1 correct?
Sent from my SGH-T959 (Samsung Vibrant)
i have try that and nothing
i have try easytether driver
the msi program and all sort of things
and im in 2.2
So USB debugging won't work. Kies/Sammy drivers won't work. I have a radical idea. Maybe your computer won't recognize the drive as a Mass Storage device b/c the drive letter got deleted somehow. This has happened to me on a few phones when flashing-fantastic.
Try this and see. It is for XP but I suspect there are similar solutions if you are on W7.
ill chek it out but i have try my phone in 3 direrent computers and nothing :/
the strange thing is when i plug it in to the PC it only charges
but when i plug it in to de AC adater it goes into debuging mode 0.o
Now i turned debuging off and turned mass storage on
and when i plug it to charge it says USB connected phone conected to computer 0.o
Try these steps:
1. Disconnect your phone from your PC
2. Setting
3. Wireless & Network
4. USB
5. Click the last option (don't remember)
6. Reconnect your phone again
Good luck

[Q] XT910 (4.0.4) Wont connect to PC

Hi everyone.
So I have a Motorola Droid RAZR XT910 its on 4.0.4 OTA with no root.
The issue I have is that I connect the phone to my PC via USB cable and it does not pick it up.
A few things you must know is:
•I have windows 7 32-bit and
•I am using the cable that comes with my phone
What happens when I plug my phone is the computer says installing drivers for unknown device and then it claims to have successfully installing them for "unknown device". My phone does give me option to chose what type of connection I want but it does charge.
Things I have tried:
•A different cable
•A different PC
• Re-installing drivers
• Re-installing Motocast
•Trying with USB Debugging enabled and disabled
•Different USB ports
•Factory reset
•Different USB ports
•Tried installing PIM Sync form Google Play Store
So yeah that's my problem any help will be helpful...
Try the drivers here:
http://www.motorola.com/consumers/v...59431210VgnVCM1000008406b00aRCRD&pubid=987654
When you try another cable, make sure that works with another device, and not just for charging.
The below instructions will help you troubleshoot if there is a problem with the usb connector on your phone.
1.Power off and disconnect usb cable.
2.Press and hold vol up and down, then hold the power button.
3.You should come to a boot mode selection menu.
4.Press vol down twice to highlight AP fastboot, press vol up once to select.
5.You should see AP fastboot flash mode (s), with last 2 lines saying "Connect USB, Data Cable"
6.Connect your USB cable to your PC and phone, and see if it says USB connected.
7. If nothing happens then it's probably a hardware problem, get it repaired.

Hi thank you for your help.
So I did this method on my PC and it was unsuccessful but i tried it on my mothers and it worked!
So I will update the drivers on my mothers PC and see If I can successfully connect to her PC and use USB mass storage for the first time since I've had Ice Cream Sandwich!
I will keep you updated
Its definitely software. Ill have to wait till there's a rooting application that doesn't require a connection between a PC and phone. One rooted I can flash a ROM from there on...
On your mother's PC, it worked in AP fastboot right? As in the words "USB connected" appears on your phone.
From there you can flash a rom.

I can flash fastboot files which I dont want to do.. I want to flash custom ROMs which require root.
The ap fastboot worked for me but when i restarted the phone it still wont connect with mass storage. i do not own a motorola usb cable mine is an LG and i dont really have money to buy one. bought the phone on ebay and it did not ship with one so ive been using this. it only connects as charging.

Bricked - Fastboot and not being detected by PC

Hi,
My phone just starts into fastboot after a failed setup. I'm trying to recover it but it isn't being detected by my pc. I've tried a lot of USB cables and it is not working.
Even without the properly drivers it should appear at Windows Device Manager, right?
It appears that it is a hardware problem. Before that I've been unable to connect it with my PC, and I've ordered a USB board replacement. I've aleady replaced it, but it is not working.
Thanks.
Try with a deep flash cable or disconnecting the battery and connecting it again

asus rog phone usb drivers foe windows 10 please help

asus rog phone usb drivers foe windows 10 please help
Drivers aren't needed for Windows 10. Are you connecting to it USB-C to USB-C or using an adapter from USB-A to USB-C?
Yes there is no need to download drivers. They will install themselves once you connect your device to the Computer/laptop. Few suggestions try one by one:
1. Restart the computer.
2. Enable developers mode(USB debugging) on your phone and then connect the phone to your computer. If your device is still unable to detect your phone.
3. Change the USB plug your connecting through.
4. Update your PC to the latest update and try again.
