I recently purchased a refurbished Mi A2. Today i tried to connect the phone via USB to my PC (tried Win10, Manjaro & Ubuntu) which did not work. While I can charge the phone it is not recognized as a storage device. When looking at the USB configuration in the developer options all the "use usb for" options are greyed out.
It runs Android 10 with the Dec 2020 security update. Since I already tried pretty much every solution recommended in other threads I was wondering if it is an issue with the current android version or if the charging port (which should be new after refurbishment) has to be replaced.
I would appreciate any input or help. Many thanks!

Hi guys, so I have a little bit of an issue! I've had my nexus 6 for about 3 months and i'm not sure when it happened or why but some how and some way no matter what rom I'm running, USB connection to desktop no longer works. I have tried turning adb on and off, reloaded drivers, and tried other computers. When I monitor device manager in Windows 10 no new devices are connected at all, just does not show up. No unknown device, adb, USB, nothing. So I'm not sure what I should do, I was thinking of claiming warranty however trying to avoid it. Any suggestions??????
P.S: Mounting external storage devices using otg is successful.
May there be some problem with your cable. Try different cable on all available usb port.
I've done that, no success
Excellent day to everyone, I request your help please.
I have note 5, Android 6.0.1, everything worked excellent but from one moment to another it does not go into fast charge mode and when connecting devices otg only tells me in popup window connected USB device but it does not open the micro SD connected to the adapter.
Obviously, I already tried the charger and the cable in another note 5 and it works perfectly. I also did center of charge cleaning but nothing.
I installed the application called USB host check and the following appears on the screen;
android.hardware.usb.host.xml
okay
handheld_core_hardware.xml
USB host not enabled
tablet_core_hardware.xml
not found
Apparently the same application can search the necessary files and write them in the relevant path. The problem is that I do not have root so I can not write to internal system.
No can do root because the pc does not detect the phone even activating USB debugging.
Any ideas? If I restart the phone to factory with all its wipes will be solved?
Is there any way to do root with no computer involved?
I thank you for your contributions and if any information I lacked to mention I beg you to tell me which to see if we can take it forward.
In advance, thank you everyone.
I've been using my Mi5 for 6 months without any real issues, the occasional bug like fingerprint scan missing ect but overall no problem. Right now I am experiencing a problem that is driving me crazy. The USB options do not show up, only that it is charging. My PC doesn't recognize it anymore, and gives error 43. (USB device descriptor failed.) MiFlash, MiPCSuite all do not recognize it either.
Any help or solution would be greatly appreciated, I've spent days combing through potential fixes to no avail.
What I have tried:
-Mi PC Suite
-Mi Flash
-Default Android Drivers
-3 Different cables (2 xiaomi, 1 off brand)
-Factory Reset / Data Wipe
-QShortcut to force mtp usb options
-Developer options USB debugging on + selecting charging / mtp
-Reinstalling INF
-Disabing drivier signature enforcement
I've went as far as trying a different rom ect to no avail. It seems to revolve around the mi5 not recognizing usb connection, only charging for instance can't use usb charging
I've tried many options in terms of drivers, replaced the usb port and tech told me it was most likely motherboard issue and then tried to sell me a new phone. Unfortunately, I am living somewhere without many options for authorized support so looks like I'm out of luck.
Also tried different pc's, cables, roms, ect. All seems to stem from mi5 no recognizing usb
Hi,
Sorry not a solution but I'm having exactly the same problem too. Was fine for the first few months but then suddenly nothing. I've also tried it (with different cables) on :
Windows 10 PC
Windows 7 laptop
Linux Mint laptop
Macbook Air
And nothing but charging mode. Changing setting in developer options does nothing either. I've resigned to the fact it's most likely a hardware problem
Hi,
i had the problem that mi5 was not found by pc after a fresh install of windows 10 64bit.
I found a solution somewhere in the www
I have downloaded and installed the windows 10 N pack ( media feature pack ).
After that, restart the pc and try to connect the mi5 again.
This solution worked for me.
I have the same issue. Is there any solution? Is it covered by the guarantee?
Same problem here with mi6, maybe if we replacement de usb port of the phone?

Same Problem, Need Help
does anyone have same problem i need help and probably a fix to this problem, fastboot not detected too, i am currently using windows 10.. driver that i found online does not help either
hi, i need help in this case aswell. initially there no OS on my mi5, computers absolutely doesnt see phone (no unknown device etc, just nothing), so i can not send any zip file to install an OS. i can access trwp, tried OTG connection but it doesnt see either
Wow.. so I'm not the only one who has this issue.
Too bad there aren't any solution in this thread. My guest that it has something to do with the hardware. My phone is not recognized on PC and it is not charging properly either.
The strange thing is that it can charge on unknown chargers. It doesn't charge on "authentic" chargers (Xiaomi chargers, well-known brands like Aukey).
Solution
Guys (and gals)
I have the solution, i was as desperate as you all and it took a lot of digging into it, IT IS SO SIMPLE :
Download the app "USB SETTING" for MIUI and just turn on the option for file transfer, it also solves the ethernet problem. It worked for me, that's it.
(I also activated the USB debugging in the developer settings but I don't think it helped, as a matter of fact the right setting is present there in "select USB configuration" but refuses to work on my phone at least)
I hope it helped,
All the best on your paths <3
I had the Sony XAV-AX100 and everything worked great. I just switched to the AX5000 and now AA drops out all the time. It will either freeze up, or it will come up with a warning that there is no connection to USB. I have tried a different usb cable. Same problem. I am using the same phone Galaxy S8 and the same high end USB cable. I uninstalled AA from phone and re downloaded it. Same thing. It is very random. It will boot up AA just fine then go to Pandora play a song or two then drop all connections. If I unplug and wait and plug phone back in it will work for a short time then drop out again.
Anyone have any thoughts on what to try here?
I have talked to Sony chat session not much help here.
Thanks
I talked to Sony a little bit (from what I could understand) They think it is a MSC "Mass Storage Connection" connection with USB. But Android has not had a MSC connection since maybe 2015. So why would this be happening now with this firmware? Anyone have any suggestions on how to get phone to a MSC USB connection instead of MTP? Or the radio to use the standard MTP connection on every Android out there.
I got the AX5000 on Monday and have been fighting the same issue. I have a Samsung Galaxy S7 running Oreo (8.0) and have tried everything from a physical perspective (cables, flash, factory resets) but no luck. When I spoke with Sony today, they tried to tell me that AA was not supported on my car (2012 Jeep Wrangler) which ignores the fact that this is an after-market upgrade. I agree that it's likely an issue with how the head unit communicates with the phone. The only place I have found to change USB settings is under the Developer Options. The available options are Charge this phone, MTP (Media Transfer Protocol), PTP (Picture Transfer Protocol), RNDIS (USB Ethernet), Audio Source, and MIDI. I'll try each of them and resort back on the results.
Yes with talking to Sony they said that the phone USB has to be set to MSC for USB1 to work. Well you would think that they would know that has not been used on android run phone for years. I tried developer mode and setting debugging to on. and even tried different USB configurations in debugging. like Switching it to Audio Source. As soon as plug my phone in it kicks it back to MTP. This is a easy fix for Sony they have the MTP setting on the USB 2 wire. But we will see how long it takes them to do an update on this since they just did one last week. Very frustrating I have the AX5000 on my Harley. So it is not very convenient to mess with it.
Please do post if you find some kind of solution: As I am sure Sony will be awhile.
I had the same result with attempting to switch the USB mode. It switches back when the phone is plugged in. A firmware update may be our only hope.
Well not sure if I found a possible fix. I put my phone in developer mode. Then switched the USB to debugged. and used my original USB cord that came with the S8. For the limited time that I have been able to check it out it has worked. Keep in mind this is on a Motorcycle. So time to work on this is limited. The problem I have is that the original cord is 4' long and I have no where to tuck it in. I have tried several different short cords (amazon) and they all will work for a bit but AA stops randomly.
I still think it is funny When I talked to SONY they said that this radio would not work with my phone USB protocol. But I have talked to several people that say they have no problems with same phone & same radio.
Anyone know where to get a 1' USB cord that would be the same as stock Samsung S8 cord? Yes I check with US cellular. Phone carrier..
Thanks
Does anyone know if Sony has fixed this issue yet? This is really the only deck I want. The 2330 was another I was looking at but the screen is resistive.
Still an issue for me. No firmware update beyond 1.01 and no settings or application conflicts that I've found.

connection to AA should automatically set your USB to MIDI.
if it doesn't, try setting MIDI manually before connecting the cable (and double check it after connecting).
Yeah, tried that with my Galaxy S7 and it auto-switches it back.
I have it working using a Pixel 3 XL.
First, enable developer options
Settings > About phone > tap Build number 7 times
Go back to Settings, then System > Advanced > Developer Options > Default USB Configuration > Set to MIDI
Hello all,
I have updated my P30 pro to version VOGUE-L29C 10.1.0.179(C431E23R2P5) according to instructions posted here (dload). So far so good. Unfortunately, the smartphone is now no longer recognized by any PC via USB. Old backups from a USB stick can also not be used. It can only be charged via USB. I have already tried to check the USB port via the menu *#*#2846579#*#*. No preassignment is displayed. Setting any option has no effect.
I also can't reset the smartphone with any older version. I have tried several. The update reports an error when checking and restarts the smartphone. Recovery is also blocked so I can't perform a wipe.
Has anyone else observed this effect and possibly a solution or a tip for me? My main problem is that no file or photo transfer is possible via USB.
In the developer options, all settings for ADB via USB, USB file transfer and OEM unlock were enabled.
Thanks for your time and support.
Best regards from Germany.
Andreas
I've had that problem on a p30 pro. Headphones, TV out, super charging all worked, but not data connection to pc, absolutely no reaction besides charging. I've read that forcing update did that to some phones, but updating from phone to the next version would solve that. Didn't solve it for me, when it updated... I could access its memory using Huawei share and network neighborhood from Files. Bought it that way and sold it after 1 month.
