I have a big problem: PC does not see my phone (like it is not connected). The phone charges normally when connected.
Phone is Huawei Mate 9, MHA-L29, version 9.1.0.252(C432E7R1P8patch03), EMUI 9.1.0, Android 9 and I have tried on several computers (Windows 2007 / 8. 1 / 10).
USB debugging is turn ON and so is the HDB, but still nothing.
The phone was working normally for years, but since two months ago I can not connect it to PC, and can not transfer anything to and from phone.
I tried everything:
- Restarting phone
- Wipe cache partition
- installed latest HiSuite
- installing ADB driver on PC
....
Is there any solution to this problem?
Thanks in advance for every suggestion

Hi Guys,
I have an Nexus s on stock running 4.1.2 kernal 3.0.31
I'm only new to smartphones and I think i made a boo-boo. While connect over usb, i turned off mass storage mode and pulled out the cable. I only then realised that I should have safely ejected on Windows 7 before turning off mass storage mode.
Now my computer will not even recognize the device. It pops of "usb device not recognised"
I tried installing the samung usb drivers - no results
I tried unistalling some usb ports in device manager in windows and rebooting - no results
help!!!!!
Thanks in advance
I just installed the pdaNet application for windows and that didn't recognize the nexus either!!!
Should I factory reset the phone?
i really wanna install Cyanogen Mod as the phone is running quite slow!!
Hi Guys,
I've had a few problems with my N5 recently...
If I plug my N5 into my PC via the stock USB cable and boot into the Bootloader (PWR+VOLDN) then it will allow me to flash the original N5 firmware, located here: https://developers.google.com/android/nexus/images, this would indicate to me that there is no issue with the actual devices ability to transfer files via USB connection... Right?
No!
For some strange reason my phone will allow me to push a full factory image to it and will also process any Fastboot commands that are sent to it but as soon as you boot into something like TWRP and try to control the phone's ADB functionality it will not find the device at all! The new MTP option in TWRP 2.8 will allow my computer to see my phone's MTP connection for about 1 second and then will immediately disconnect, the same happens when trying to connect to MTP from within Android too.
USB debugging doesn't show that it is connected when my phone is plugged into my PC and Windows makes the 'device connected' sound and then straight after makes the 'device disconnected' sound...
Any ideas? I am certain that this is an issue with my handset's hardware or software rather than any of the computers or cables... I have tried 3 different cables (including the stock cable) and also three different computers (Windows 8.1 @ Work, Mac OS X @ Work and my own personal PC running Windows 8.1 & Ubuntu @ Home)... All OSs and all computers run into exactly the same issue, device connects briefly and then disconnects.
I have troubleshooted issues relating to the driver. This is not the issue... Device Manager cannot even see the hardware after the disconnect.
Thanks for any help in advance,
Lewis
Also:
-Android does not detect that the USB is charging the device unless the device is booted with the cable attached (if it's not attached before the 'Google' screen then it can't see the USB input at all, within android or TWRP, of course...).

It's most likely a driver issue.

Not a driver issue.
3 different Nexus 5s, 5 different workstations. Other two Nexi are fine on all 5 PC's.
1 PC used for ADB forensics, 2 used for ADB development work, one known working for ROM'ing / rooting.
Phone has been factory reset, factory ROM'd from Fastboot. Connects fine on Fastboot. Will not connect on ADB / MTP.
On a fresh PC / phone reboot, the PC will detect the phone for just a second and then it will not reconnect until process is completed.

What's your adb version?
Went on for about 2 weeks, then suddenly went away on its own. I have no idea what the problem was or the solution. Sorry.

Since I upgraded my PC to Windows 10, I've been unable to get a connection via USB. I've tried many things following several hours of research/trial and error but not managed to get anything to work. Kies just displays a USB connection error and I get the yellow warning triangle with "USB device not recognised" popping up on connection of the Note to my PC. I do have a Windows 7 Ultimate partition as well as Windows 10 but even that is unsuccessful. I used to have full connectivity with my original Windows 7 Home set up but I don't want to roll back to that, as I do overall love Windows 10.
Anybody had this issue and resolved it?
Many thanks in advance.

I've done this several times, from different sources, without success. I'm reasonably IT literate but am stumped trying to get this to work on Windows 10.
Hello everyone, until two days ago connecting the mate7 via USB, the menu asks me whether to allow USB debugging and other options, and I put the single charge option when connected via usb I thought it was a pre-selection, as happened every time I linked it but Now I can not connect via uSB memory !! Hi Suite doesn't work.. laptops (one with Win7 and the other with win 10) don't see the phone. I can just plug in the cable, charge only and can not activate the menu where the mass storage and more.. I looked in the settings and I also enabled the developer options and despite having turned on and off several times nothing happens. It remains only ever being charged. Even HiSuite says device offline. Does anyone know I indicate that steps should I follow through?
Thanks for you help! :fingers-crossed:
Android version is 4.4.2 with EMUI 3.0 and firmware B137
I'd be updating that to at least Lollipop. Might just fix the issue same time, but Marshmallow on B560 is good.

Thanks for your answer. I have tried and now on 560 but the problem is still the same.
A few days back my One plus One device got stuck in bootloop when I installed an App update from playstore ( Google app). I downloaded the One Plus toolkit from their site and installed it but even in fast boot mode the device is not recognized by Win 7. I changed my OS to Win 10 still it says the same thing " one of the devices plugged to the computer has malfunctioned and Windows doesn't recognizes it." I uninstalled the drivers for the USB controllers and checked for hardware changes , still the device is not recognized. Unless it is connected I can't run the toolkit to root the device or flash a new ROM. Why is this happening?
