Question I need some help please! - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

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)

No usb connection?

Hi everyone,
I'm not sure if it's just me being a noob or if there is something borked on my P6 but I cannot for the life of me get any of my computers to recognise my P6 when I connect it via USB. I have installed the Mobile Drivers and have also tried putting it into USB Debugging mode but the computer doesn't see the phone. It does, however, charge it via USB but I get nothing else saying I'm connected and HiSuite also reports me as not being connected. Any ideas?
Ok, this is solved. Apparently, the phone's USB cable and another that I tried did not work with the phone but I swapped out to a third cable and it works fine.

[Q] LG G3 USB Not working on PC

Hey Guys
Being in IT I always tell people it's a bad Idea unplugging a USB device while you are transferring data to or from it. Should have followed my own advise. I was uploading to my G3 while plugged into my PC when the phone wrung. So Mr Smart guy unplugged it to answer it. After that it was just a no show. It connects and show up in my folder manager, but when I click the device, there are no directories or files. I know if you do that with a USB drive, you need to format it to get it working again.
I'm hoping for an easier solution on how to possibly reset the USB on the phone.
PS. After restarting the phone and PC - still no show - Doesn't work on any USB ports on my PC (USB 2 or 3). PC USB port working as I can plug other devices into it and it connects.

Zenfone 2 not detected when connected to PC

I was trying to transfer some files to my phone through a USB cable today, but the phone was not recognized by the PC at all (Even though it was working a week or so ago). I had some issues before with the cable needing to be still in a certain position or it would disconnect from the PC, so I tried using another USB cable which didn't work either (I tested both USB cables with another device, and both cables were working and the other device was recognized by the PC).
I also updated the USB drivers on my PC with the official drivers on the ASUS support page, and tried putting my phone in fastboot and recovery mode, but both were still not being recognized by my computer. My phone still charges properly, but I am wondering if the USB port got damaged somehow so that it can't connect to a PC anymore?

uninstall and reinstall the drivers. Ensure that phone is not connected during the process.
also have you upgraded your pc os ? if yes then its a little cumbersome to get the same working...
i changed from stock to cm, it is showing well now ... using RR now
Is your phone encrypted? If so you need to unlock in order for your pc to recognize it.
Thank you both of you for the help, unfortunately, my phone was not encrypted so there was no need to unlock in order for it to be detected. Uninstalling and reinstalling the drivers didn't work, and my PC was already on windows 10 since a few months ago. I would also prefer sticking to the stock ROM for this phone for now since they keep coming out with updates.
In addition, I tried using a USB OTG cable to see if the phone could detect the USB drive and my phone couldn't (it has worked before, and my old Galaxy Nexus could still detect it). I also tried plugging my dualshock 3 into the phone, and it also couldn't be detected (also had worked before).
It looks like it's actually a hardware issue and my only option is to RMA it now. I'll have to do it at a time when I don't need my phone as much or when I am not as busy.
PS: In case anyone else has this issue in the future, quick charging also no longer works
zenfone2 I also experienced that, and I have tried several ways, but remains unchanged. I was dizzy today :crying:

USB charges but no data

Hi, my phone stopped being able to get a USB data connection. The port is physically intact and does not wiggle. I've tried two different Macs and one PC, different USB-A to -C cables (all verified by Benson Leung). Also toggled USB debug, MTP and PTP modes from Developer Options, rebooted phone and computer. When I plug the phone in, it only goes to Charging mode. Android File Transfer doesn't see it and 'adb devices' comes back empty. There is no notification offering me to select connection type. Did I miss anything or is it time to send it in? Thanks, Tony
What OS are you running on your Windows - checking your Device Manager under Control Panels - are all the Google / N5X drivers installed and working correctly before this ? Try uninstalling, reboot PC and re-install them - and, use different USB port to connect the cable (what kind of connections are you using ??)
Can you run ADB ?
Thanks I'm primarily using a Mac (10.10.5) but the PC was running Vista. It was a borrowed PC so I didn't install the drivers. I don't think it's a driver issue though since nothing shows up in device manager and the phone doesn't offer to switch out of charge-only mode. Also the same Mac worked previously.

LG G7 EMW (Brazil - Claro) USB does not work, but charging and EDL mode do

Hi all.
I have a wonderful LG G7 (model G710EMW from Brazil carrier Claro).
Recently I've tried to connect it to my new car audio system that supports Android Auto and it didn't work as expected. Long story short, I've discovered that USB does not work on my phone.
Charging works alright, but anything that requires an USB connection simply does not work.
When I connect my phone to my PC, the phone starts charging, never shows the "USB connection" notification icon and the PC does not recognize anything. The phone also does not allow me to choose the kind of USB connection that is to be used (you know, MTP and the other options). When connected to PC through USB cable it displays exactly the same behaviour as if it was connected to a regular charger.
I have tried different cables, being two LG original USB-C to USB-A cables, an USB-C to USB-A from Xiaomi and a generic brand USB-C to USB-A charging and data cable. All of them show the same behaviour.
I did soft reset my phone, thinking maybe some app I downloaded could be interfering, but it also did not change anything. Also hard-reset, but no change either.
I've already tried replacing the circuit board with the USB plug but that also didn't change anything.
The only time USB works is in EDL mode, which shows expected behaviour. PC recognizes the "Qualcomm HS-USB QDLoader 9008 (COM3)" port and with QFIL I can navigate through partitions and stuff seems to work.
I would try installing a different ROM, but as I would need to cross-flash to unlock bootloader (default ROM does not enter fastboot) I am stuck on the USB issue now.
Has anyone seen something like this? Any suggestions to what I could try?

I did try on another two different computers, all on Windows 10, and none of them recognized the phone except when the phone was in EDL mode.
I haven't tried installing drivers for the phone, before when it worked I never had to manually install anything for the PC to recognize my phone.
I'll give that a go, thanks!

Just to let you know, I could not find the USB driver for regular usage of the phone connected to the PC. What I found was drivers to use the phone with ADB and drivers for EDL mode.
I got to test the phone on a Linux Manjaro installation and there the computer also did not recognize any new device with "lsusb" command, whereas using a working LG G7 ThinQ the output of "lsusb" was:
Code:
Bus 001 Device 004: ID 1004:61f9 LG Electronics, Inc. Optimus (Various Models) MTP Mode
Note: the working phone had the USB connectivity option set to "Charge only" (or something like that, my phone is in Portuguese).
