Question PC does not recognize the phone - Samsung Galaxy S21 Ultra

Hi, I have a question. I upgraded to A12 and from then, when I connect my phone to the PC through USB it did not recognize it. I try different USB cables but still the same. Maybe samsung have new drivers?

I tried various USB cables, uninstalled and reinstalled the drivers, in the development options I have USB debugging enabled and the default USB connection option for file transfer and tried on several computers and still nothing. I have no ideas what to do to make the phone discoverable again.

hmmm mine works.. have you checked the USB settings? make sure Use USB for "Transferring files / Android Auto" is selected.

[Q] USB device not recognized

Hi, I've been transferring some stuff to my galaxy s and now i'm getting this error everytime i attach the USB (USB Device not being recognized). I already reinstalled the samsung USB drivers, uninstalled and reinstalled USB root hub drivers, used a different USB port and restarted both PC and galaxy. Anyone have any idea how i can get my device to get recognized by my pc?
no one's encountered this problem before?
I get this on and off - i'm on Win 7. I tried all 4 ports and my hub and sometimes it plays ball - sometimes not.
I often find if I change the phone from 'mass storage' to 'ask on connection' it seems to improve its chances.
Worth a try.

I tried this as well including turning USB debugging on and off.. no luck though. Only thing i haven't done is format the internal SD, but I dont want to go there unless there really is no chance of fixing this. Any help you be greatly appreciated!

[Q] Kies won't recognise device

I've had this problem for a while now. I've got Kies 2.0 and it won't recognise my phone. The MTP application on the phone says "Connected. Press the home key to quit Samsung Kies" but Kies just displays "Connecting...", and stays on it forever.
I can access the files fine on Mass Storage mode.
I've tried all of the following! :
- Setting my phone's USB mode to ask on connection
- Reinstalling Kies
- Flashing a new ROM
- Changing USB Ports
- Reinstalling the USB Drivers
- Deleting the "Soundhound" directory - most people said that works for them. It doesn't for me
- Just about everything
I'm running JPY Froyo on a Galaxy S, in the UK, flashed with Odin. Please guys, help?
What's about:
- Updating your drivers?
- Using the stock cable with no Hub?
- Cleaning with alcool?
Hi there
I'm not sure what you mean by updating my drivers. Which drivers are you referring to? All of my drivers are up-to-date already.
Secondly, I am already using the stock USB cable with no hub. It is not a problem with the USB cable, as I have said, Mass storage mode works absolutely fine.
I'm also not sure what you mean by "clean with alcool". Are you suggesting I dip my phone in vodka?
Thanks ;P

Hi,
I added those just because they are not in your check list.
About drivers i mean your OS system driver (USB drivers, not the samsung one).
About the alcool part i mean physically clean your USB ports and cables.
I assume you use the last Kies software? Do you have another PC to test it?
For a more detailed troubleshoot, you must now provide more data:
OS, more specs: roms/kernel/ etc...

very weird pb.please help

Hy guys,
I was trying the other day to flash a friends Galaxy S stock 2.2 but i couldnt connect the phone to the pc. In the pull down menu, it didnt appeared the dialog to click to go for usb mass storage or anything.
I've selected USb Debugging, clicked in the options for USB Mass Storage, and when i connect the phone to PC and cable, both play the connected sound, but still nothing more. What could be the pb? and how can i solve it?
Pleaaaaase help
And thanks in advance
also to mention. I'm running win 7 on 64bits, drivers installed correctly and my phone has no pb at all when it comes to connect it to the PC.
So....Odin not recognizing, PC not recognizing phone...what to do....?
try different ports or re-install your drivers(kies) take a look on the Themes and Apps section i saw a thread for drivers... try on a different computer....
have tried reinstalling the drivers, also using all the ports available on my pc. still the same pb.:-<
Definately PC issue. Reinstall Kies drivers.

I don't know which rom you have flashed prior to your problem with the phone.
But if it was my phone the first thing I would do is to go into recovery and do a
factory reset, doing that just might fix the issue with not being recognized by your
computer correctly.
It might also help to uninstall all the usb drivers and kies from computer
then only install the samsung usb drivers for windows.
Good luck,
Have a happy merry Christmas.
