Hi,

I,ve tried to connect my S21 to my PC. This has worked previously so I,m at odds as to what has happened. Everytime I connect my phone I get the USB Not Recognised notification.

I have googled all and have deleted all USB Roots in Device Manager, Restarted the PC and still the phone is not showing.

I have tried in another laptop and same thing is happening.

Is there any settings within the phone that is stopping this connection?

Find it strange that is was working before. The only thing different would be a Windows Up-date.

Any help would be much appreciated.

Cheers.

@Gerrymac: Please can you try heading to Settings > Apps > Tap the 3 lines with the downward facing arrow, to the right of 'Your apps' > Show system apps (toggle this on) > OK > Scroll down, and tap on 'USBSettings' > Storage > Clear cache > Clear data, then restart your device. 

Next time you connect to your PC using the USB cable that came packaged with the phone, please try swiping from the top of the screen to the bottom, and check the notification panel to see if the connection has been recognised, and tap the notification to explore your available options. Let me know how you get on.

I am having a similar problem with my S21 Ultra. I have been using the OTG connection for an external HDD. It's worked fine for years and all of a sudden after an update, the phone won't recognize the HDD. Something got screwed up with the update. How do I fix this?

FYI, The fix by AndrewL did not work.

Hi, did you find a solution to this. I have the same phone and the same issue. Except that it never worked for me.

Unfortunately no. My usb then stopped charging. I took it to the repair shop. They said the port and phone were fine and suggested I try a new cable. Something weird is happening, now it charges.

Yeah, no the new cable from the box doesn't help it either. it's always just charging. I think samsung just needs to accept that this is an issue on their end and fix it. cause the same cable, laptop and port works with another brand's phone. It's annoying cause i'd like it to work on samsung. 😞
