USB Not recognized (Android Phone)

[Davidudu]

When was the last time the phone was power cycled?

What security apps do you have running? See if it helps to disable them to test and see if they are hindering.

On mine with 8.0 to see if USB is connected check it with out being connected and then connected.
Go under Settings then Connected Devices and scroll to the bottom.

Computer go in to the device manager ans see if the phone is listed there? Withe the phone connected.
Is there a Red X or Yellow ?
You can also right click on the phone and select update driver and see if that helps.

I don’t have any security apps. I can’t seem to find “connected devices” that you talk about. I can find a list with all the programs I have on my phone but that’s it.
And lastly, what do you mean by red and yellow X in device manager? When I connect my phone it’s listed under “USB devices” but it doesn’t recognize it. It just says “Unknown USB device”.[/color]

red and yellow X in device manage

Is there anything with a Red color X on it and or Yellow color ? (question mark)

. I can’t seem to find “connected devices” that you talk about.

That was where it was for my phone things are different depending on the manufacture.

When I connect my phone it’s listed under “USB devices” but it doesn’t recognize it. It just says “Unknown USB device”.

See if this video helps.

Download the drivers for Windows here

https://samsungsupportdrivers.com/samsung-galaxy-s7-drivers-download/

Several sites were listed but I’d only trust drivers from Samsung and not other sites.

Also, don’t allow Windows 10 to update drivers.

Thanks everyone, I will try these things! Update coming soon.

[Rustys]

Thank you for keeping us up to date.

Downloaded drivers and the program Kies that you got with the download. Nothing happens though. Uninstalled ALL my USB devices, turned off the pc, then plugged in my phone and started the Kies program and tried to “emergency recover” the phone like the program suggested, but it’s impossible because the phone won’t even show up.
In device manager I can’t even see “Portable Devices”…
I can’t see any red or yellow X in device manager either.

I watched that youtube video a couple of days ago but I don’t have the same options as he do in the video. The “Portable Devices” for example.

I have tried so many fixes. It has to be my phone though right? I didn’t work on my friends pc either…

While in the Device Manager lets see if this shows it.
Select View and then select Show Hidden Devices

It that your phone listed under the USB list in post # 21?

[Davidudu]

Yep, that’s my phone! # 21 with the warning icon next to it.
I click on hidden devices and I can see some new devices but they don’t do anything. I have tried reinstalling them and uninstalling them several times.

[Rustys]

Are you logged into you phone after you have connected it?
My tablet will not allow me to access anything unless it is unlocked.

Yep, that’s my phone! # 21 with the warning icon next to it.

Since it is try following the video from doing the install drivers manually see if that helps. from post #17

It didn’t work. I have tried many different samsung drivers available there.

When you tried it on your friends system did you install the Samsung USB Drivers?

That may have been the reason it did not work on your friends system.

[Davidudu]

I didn’t! I must try that! Will be back this afternoon. Hoppfully it will be a success.

I have a Samsung phone and tablet. I have never downloaded nor installed the Kies program anywhere. My phone and tablet are recognized on Windows 7 and XP computers. I don’t have 8.8 nor 10 to test.

I have tried many different samsung drivers available there.
You should have exactly one driver, the one for Windows 10 either 32 bit or 64 bit, whatever your computer is.
Remove all the drivers not needed because that can be causing issues.

(although it says 7, this is for 8.1 and 10 also)

Thanks. I found a lot of old drivers that were greyed out. I have uninstalled every one I think. How should I proceed now? I tried to plug in my phone once again and reinstalled the driver but nothing happens still. It felt good to remove all those hidden drivers though.

Is it safe to remove all the greyed out drivers? Let me give you a link. There are some microsoft drivers there which I’m unsure of…
And also, what’s up with my mouse drivers? I constantly have 2 drivers there and if I uninstall one it just appears again after a while. It’s the same with my keyboard.
