Problems with USB connection - Xiaomi Mi A2 Lite Questions & Answers

Hello! I have a mi A2 lite, I can't connect it to the computer using USB, it doesn't install drivers, it doesn't appear on installed devices. I've tried all the tutorials available on YouTube, but it doesn't work, does anyone know what I could do to fix this?
- I already downloaded the drivers and installed manually, but nothing changes.
- I've tried on multiple computers and none work
- When I bought the cell phone it connected, but after a while no more.
Does anyone know any solution to this problem?
Thanks!

Did you allow the phone to talk to USB. You must use the notification to enable file transfer or set the default in settings or enable debugging if you want it to show up to USB.

It does not appear the notification, but I have already tried to activate by the settings too, I already connected the debugging mode, but it also did not work. When connector it only loads, there is no other action.

I'll take it to a technician to check it out, thank you very much.

I have the same prblm ...... any solutions? Help me please

Same here on v11.0.12. Its a driver issue. You need to install latest xiaomi drivers + qualcomm drivers. I fixed it before but it doesnt work again after i uninstall drivers.

I connected phone to PC with only old original short cable, no other cables worked :/

Have you tried to clean phone's USB socked? There are some spray contact cleaners, that can be used for this purpose.

[Q] PC won't detect Arc

Greetings!
Past couple of weeks when trying to connect my Arc to the PC it will not pick it up. It charges OK with the green light showing on the side but absolutely no indication from PC or laptop that a phone is connected.. I have 3 different cables and another laptop - having tried all the cables on both machines - still no joy.
No notification in the pull down - nada!
Reinstalled Win7 and factory reset phone half a dozen times - still nothing!
Running Win7 64bit but have never had issues with OS previously up until a few weeks ago!
Service provider was as useful as an ashtray on a motorbike!
Anyone know a solution?
Thanks

Thanks for the reply TheHaso. Should have mentioned I have tried with Companion installed and not installed, updater installed and not installed. With debug on & off, MTP on & off, MSC on & off, storage mounted/unmounted.
Really strange to be honest!
check your 'Device Manager' on your desktop,, it will show you if any hardware connected and not working propely.
right click and try update driver if show caution on portable devices.

Also tried this for a solution buddy.. Thought it was a USB driver had slipped off or something.
Truly baffled! If it's charging fine then why would pc companion not detect it :-S

I'm sure you must have already done that but may be try updating with a different driver and see if it could solve problem. I know because it also happened to me.

Greetings, which other driver would you be referring to? I have literally tried everything but still no detection from PC in MTP or MSC.

Uninstall the driver from device manager, then restart the pc and connect to another usb port
From my sexy LT15i
This will work...
I have almost the same problem on my ARC.
Download MyPhoneExplorer on your PC and install it.
Download MyPhoneExplorer Client from the market and install it on your phone.
Turn on USB debugging and connect your phone with your PC.
This works on my arc and i guess it will work on you phone as well..

Asus Zenfone 2 USB debugging Problem [HELP]

When I Try to connect My Zenfone to PC & also trying to connect on debugging mode then it show display that debugging section is totally disabled & showing message "Device is in Charging mode, USB debugging is disabled.
&
2nd Problem is Media Device Not showing in Mobile & PC Also.
PLZ HELP & GIVE ME PERFECT SOLUTION
I have same problem. After switching over in my car to charging only - my Zenfone is also saying "Device is in Charging mode, USB debugging is disabled" I can't find any switch to take it back. Also the same with Media Device not showing in Mobile & PC.
How to make this working again???
The PC connection mode on your phone is set to "Charge only". Idk about the stock ROM, but on CyanogenMod you just press the notification that shows up when you connect the phone to change the mode

Dear wasiq224,
Thanks for your answer, but is not working. I'm on CyanogenMod - but there is no notification shown up. Phone is quite and also PC - no message.
Even if I press under "STORAGE" -> "USB computer connection" the phone is saying: "USB is now disconnected". I checked already various menues for some settings without result. Google was also not help in this matter.

Try going to Developer Options>Disable USB Debugging, then reboot. Then connect your phone and try going to USB computer connection again, and enable whatever connection mode you want. You can re-enable USB debugging after that.
Dear wasip224
Checked once more the debugging setting's. But if the phone is connected to the computer or not connected, disableing USB Debugging is not possible. This item is greyed out all the time. See attached pictures.

I'm at work now, but you use Explorer and go to the folder where you extracted the drivers and use right-click --> properties in one of the files there. There is a tab that lists certificates. Just to be sure you can temporally disable driver signing verification.

This instructions works in windows 8.1 and 10.

Hi all,

Doesn't work for me, it says it cannot find the files. In my win10 install i have two problems, ADB only works if i disable driver signing verification and MTP doesn't work. I tried running sfc /scannow and it says WinUSB is corrupt and cannot be repaired (probably why MTP does not work). I tried using intel drivers for both and it does not work. Only ASUS works (but fails because of certificate) for ADB Composite Device, but mtp doesn't work anyway.
This tutorial could help you anyway.

Hi Kras and thank for the response!
I Tried it too but in my device manager it wont show any device related to asus nor adb.
Tryied to boot into TWRP but no MTP either.
I Tried USDBview but doesnt show. The strange fact is that the phone charges normally.
It happened after i switched to CHARGE ONLY... after that, could never go back "/
I think i´ll try to revert EVERYTHING to stock. Somethings not right.
Another information, the cellphone charges, i´ve tryied to unistall and reinstall every adb usb_driver but in driver manager, nothing appears, even an exclamation. Tried to force install drivers, nothing either. All this happened after set CHARGE MODE i´m so pissed off and frustrated
This is a shot in the dark, but in device manager you can click View>Show hidden devices.
From there you can truly uninstall all drivers, and then reboot and try reinstalling. Maybe this will help.
Also, different ports, different cables?
If it's just for file transfers have you also tried something like AirDroid or Dropbox/Google Drive/Mega?

Oneplus 3 does not connect to pc

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:
Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?
i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?
What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.
You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!
I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.
Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

I used the OnePlus cable and another cable.
Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!

Unable to transfer data to phone via PC

I was having an issue like this with my previous 3XL. It would say Unknown USB device (Device Descriptor Request Failed) . I tried multiple PCs and nothing worked. Ended up using my extended warranty and paying the deductible to get a replacement which is working fine.

all that is coming up is google nexus ADB interface, it seems like the drivers will not install properly. I cant get it replaced under warrantly as i had to get it second hand due to lack of money. It connects and windows makes the noise to inform its detected the device but no matter how many times i manually install the driver it does not work and windows does not seem to auto download the driver, this is something ive noticed on all machines I have

Question Phone not connecting via USB

My first Poco F3 is completely unlocked and running a custom rom, still able to connect to PC even now.
I have a second Poco F3 that I was able to originally connect to my PC to debloat, hadn't needed to connect it to a PC till now. Today was the day I could unlock it but when I connect it via USB cable, original or otherwise, no usb options appear on phone and nothing shows on PC. I can use the same cable on my first Poco F3 and everything works fine. I've tried multiple cables, reinstalling drivers, restarting phone and PC, trying a different PC, enabling debugging tools, etc.
Nothing shows in "My Computer"
Nothing shows in Device Manager
No usb options on phone (default is set to File Transfer)
Nothing shows in CMD with "adb devices"
Charging still works
Is there anything I can do to at the very least unlock the bootloader? Or is this not fixable?
long shot... check the usb C port for dirt/dust/fluff blocking connection...
Most probably u debloated an app responsable for media transfer. If u can, revert what u debloated.

Did a factory reset thinking that may have been the case, still no good.
Tried cleaning out the port and still no good either
I still think it's Windows. Please can you try putting Ubuntu (or another Linux distro) on a USB, booting from that, installing platform tools (ADB/fastboot etc) and then running ADB devices. Windows is very finiky sometimes.
Edit: when you plug in your phone to the PC do you get a notification saying charging? Or is there no notification? Also does it start charging the phone?
There is a delay before it begins charging and the charging animation plays but yes it does. But then there is no usb notification. Will try ubuntu and report back
Booting into Ubuntu, before installing platform tools the first phone that I knew worked showed up and showed up in adb devices when platform tools was used. The second still didn't show up, exactly the same as on windows
Try downloading the installed stock miui rom from the update menu in the miui update menu and re-install it on the phone
Unfortunately reinstalling latest package didn't help
Can't think of anything else to suggest. Sorry
If the usb connection continues to be nonexistent, is there any way to at least unlock the bootloader without using the Xiaomi Unlock tool on the PC?

Hmmmmm.....strange! I'm running out of ideas....try different USB ports on PC. Maybe it's a faulty USB-C port on phone after all.

I don't have anything like this but that reminded me of the usb-c to headphone adapter and that also doesn't work. Sound just plays out of the speakers.
Trying with Android Auto in the car, the car doesn't register a device connecting at all either.
Either the data transfer portion is somehow disabled on the device itself (which I would love to know how to enable it again if that's the case) or it's a damaged usb port. Just strange that it worked a week ago.
Something I forgot to mention, when I went to unlock the bootloader yesterday the phone did not show up anywhere except for in the ADBFastbootTools to debloat the software as a OnePlus device but then never showed up again.
