[GUIDE] [Solution] How To Get Windows 8.1 To Recognise USB Mass Storage

How To Get Windows 8.1 To Recognise USB Mass Storage On Your Phone​
I have had the problem for ages that when I connected my Samsung Galaxy GT-S5360 into my Windows 8.1 PC nothing happened - Windows 8.1 simply refused to recognise the device - not even anything in device manager - nothing - nada
However it would recognise the phone if I set the phone to download mode - but I want to use my phone as mass storage
Well after months of trying I finally found a really stupid solution
Solution
Install the usb drivers for your phone as normal
connect the phone to pc via usb cable (nothing happens other then a few beeps as normal)
now plug in any usb dongle that you have already installed on your pc - like a usb wireless mouse dongle
suddenly windows detects the phone and you can now set your phone to mass storage from the phone status bar
Every time you want to connect your phone in mass storage just plug it in then plug in the other usb dongle after

it maybe the brand of laptop too and the chipset of the laptop - there have been lots of problems with usb devices with windows 8.1 and inbuilt bluetooth too although manufacturers quickly released new bluetooth drivers as the windows 8 ones didnt work in windows 8.1
so this is just for those who have problems with their particular laptop
Similar Issue with Samsung Galaxy S
I had a similar problem when I needed to copy some files onto a Galaxy S. In the past, I had to ensure that USB Debugging was off, connect the USB cable and then select Mass Storage on the smartphone. Win 8.1 Explorer did not see the device although it showed up as SAMSUNG_Android in Eject Media and Device Manager had the phone listed under Universal Serial Device. I was able to access the phone on one laptop by selecting Samsung Kies as the connection method (showed up in Explorer under the device type rather than a drive letter) but this did not work on another laptop.
The steps described in "How to connect Android devices to PC with USB Mass Storage Mode" on device-recovery.com worked for me on both Win 8.1 laptops: enable USB Debugging, connect the phone, pull down the status bar, tap on the USB Connected entry and then Mass Storage.

What you said will not work for this phone because when you plug it into a windows 8.1 laptop the option to select connect to mass storage in status bar is not there - It just shows the phone as charging
The only way iv found on a windows 8.1 laptop with this issue (note it depends on your hardware to weather you have this problem) is to plug the phone into the laptop then plug any other dongle in - the option to then connect to mass storage suddenly appears in the status bar and you can connect as normal

USB file transfer not working on windows8.1, anyone got the USB drivers for redmi7?

On the stock ROM, for some reason the device isnt recognized when I connect it to the pc with the USB cable, tried to install mostly all the drivers I could find from google but its still not working, the device shows up as SDM632-MTP_SNsome numbers) on device manager, tried it on another OS (win10/7), worked on both but I use win8.1 as its the only OS that works well with my laptop.Anyone got any drivers or solution to fixing this.

USB Debugging - Authorisation for PC

I am trying to back up my phone using Syncios. I have all the options made in Developer Settings/Mode. Phone is Android 10, March update.
On an elderly Windows 7 machine, I get a USB Debugging Authorisation panel on the phone and I accept and connect flawlessly to Syncios.
On a much newer Windows 10 Home laptop, I do not get the panel, so cannot authorise to connect to PC.
Any ideas/tips please??
Since the Android 10 update I can't connect the phone via USB to any of my computers (win10, 7, Ubuntu), also I can't connect it in fastboot, so maybe you get the same bug on your phone.

The phone connects to a W7 computer perfectly well.
It's been a couple of months since I was able to successfully connect phone on Ubuntu or Win10. It's not even showing any notification that it is connected.
My phone works fine with both a Mac (10.11) and PC (Windows 10)... Maybe there's something you can clear data on... Maybe if you click on Revoke USB debugging authorizations?
I normally use wireless adb though. The app Quick Settings gives me a toggle in the notification shade (ADB over LAN) and then I just adb connect IP from the computer. My router assigns a fixed IP and hostname to my phone so it's easy

Question I need some help please!

Hi , my Poco F3 arrived today and i was very hyped to use it but i've come into a problem.
Neither my win10 laptop or my F3 can identify each other when i connect them via USB, i can't even find it on the device manager, on my sister's laptop it connects and identifies weirdly enough but that's an older laptop is really slow and unreliable for anything specially since its not mine.
My laptop is a new one 2020 model and it connects well to any other device ...
I've tried replugging 100 times and i've made sure USB debbuging was toggled on my poco, also made sure the usb config was on file transfer, i've tried installing various ADB drivers too but it didn't help.
Can anyone please help me out with this , the poco f3 is my first android device and i really wanted to put other roms and use the ADB fastboot tools to debloat it but without connecting it with my laptop its gonna be very hard ...
Use official USB cable. Don't use a USB hub. Connect directly to the laptop. Change a USB port.
Plug your phone USB cable to laptop, switch file transfer mode on phone drop down menu, then reboot your laptop without disconnecting your phone from laptop.
Right click on the windows button on the task bar. Click on device manager. Does any device appear on their when the F3 is plugged in. Also as said above directly connect to a PC usb port rather than through a hub (maybe use a Usb c to usb c cable if your laptop only has usb c ports)
