USB communication not working (after MIUI 11.0.5.0)

[ipfalvim]

I have a completely stock Poco F1, when i got it it had the MIUI 10 and everything was working fine. I don't plug my phone on my PC with the USB cable so much so only last week i realized its USB communication is not working at all

The only thing that changed was the official update to MIUI 11.0.5.0.
It fast charges with no problem using only the stock charger and cable. But when i plug it on the computer it spams USB not recognized on Windows 10 and no message about USB options shows on the phone at all

I only see the charging indication. On the USB communication options it shows the phone isn't connected to the USB.

Developer options for default USB dont matter (tried all of them - Transfer Files, Tethering, etc)
Already tried other cables and other PCs and no changes whatsoever.

I already bought and exchanged the USB board that goes at the bottom of the phone and the same thing still happens

ADB doesn't recognize the phone at all

What should i do? Please some advice (i cant even flash ROMs and other stuff like that)

Reinstall pc usb driver

it doesn't matter what i install or reinstall... i tried the Mi Suite, ADB drivers from windows update and internet... 3 different PCs...
It shows like no device is connected at all.. the PC doesn't see the F1 and the F1 doesnt know its connected as well (only charges)

Your cable broken. Use another usb C cable, and try connect to another PC

Try different usb port,try different usb cable,try restart windows,try clean up all usb data about connected devices (Google it), at last try different rom to see if issue still persist ...

Yep, IDK what's the deal with Windows but in Ubuntu 18.04, my phone just detected as MTP device, no set-up needed. In Windows, needs manual MTP driver installation using device manager.

I'll try on Ubuntu and see what happens.. But it's weird that not even the phone knows it's connected

I used 3 different cables on 3 different PCs

Check for build up dust in your USB port of the phone. Clean it carefully with a toothpick

I had this issue recently too with my fully stock Poco 11.05. My phone would either not connect with PC or would keep spamming connect and disconnect. I went to the service center for a different issue and just told them to also clean the USB port. They cleaned the port with rubbing alcohol and fixed the other issue too. No charge... Even out of warranty.

Everything works as it should now.

Also if you eliminate all issues... My last word of advice is try connecting device to Intel motherboard and not AMD.

as i said on the 1st post, i replaced the entire USB board and nothing.
i didn't have the time to test the ubuntu yet but i'm almost sure its some bug on the MIUI 11

I'll try to put the other USB board again. I tried to plug-in on an amd motherboard and the phone doesn't even show up as a device.

any update??

Any update? Same problem here.
Changed USB board too. But im on MAC and still not recognized. In windows got the same error..
I can only charge, No ADB/Fastboot/USB connection

Hi,
i am on MIUI Global 11.0.8 and today i ran into this issue as well.
I got two different cables here at hand. Both are type C to type A adapter cables, but from different manufacturers.
If i use these with the F1 and connect to my laptop (ports are 3.1 capable), one cable is working fine (charging and connection) the other one is not (only charging).
Both cables are data cables and worked fine during a cross check with another phone.

Another information i found somewhere is to tweak the Windows registry, but i guess this won't solve the issue.
In the end i did a cross check with a Linux PC and same here.

So it seems to me, that it might be related to the kernel/system used for MIUI 11.
Could anyone confirm, if there are any related issues with a custom ROM, e.g. Lineage OS?

EDIT: O.k. checked it myself... i observed the same behaviour with LOS 17.1... seems the F1 doesn't like specific cables.
Tried another connection wit a true type C connector cable from the phone to the laptops type C receptacle, no problems here.
So it seems it has nothing to do with USB 3.1 hardware in the laptop, but some cables simply don't work...

Cheers,
scholbert

What is the brand of cable that worked for connectivity on your poco f1, i am having the same issue with mine. Also does the serial number in your device match the one on the box?

 

[Arielxander]

The same thing was happening to me, my pocophone sometimes charged and sometimes not, the PC detected it sometimes, I had to disconnect the cable and reconnect, I thought the USB port was dying This happened to me on my 11.0.8, I tried other roms and the same thing happened. Then my pocophone was updated to miui 11.0.9 And now it seems to work normally, I no longer have any problems with charging or with the PC

Is your serial number saying "unknown"?
