usb not recognised - Ascend Mate 7 Q&A, Help & Troubleshooting

I am having Huawei Ascend Mate 7 mobile phone.
Few days back, phone charging got very very slow. It takes 10 hours to completely charge the phone. I thought it might be due to data cable. I buyed new one but same problem.
Then I connected my mobile to pc, then it showed USB not recognised.
I thought to reflash the software but for that stock recovery is required which can be flashed only with data cable but data cable is not working.
Then I tried charging my phone with a charging cable with only 2 wires. Now, the phone takes 5 hours to completely charge the phone.
Then I thought it might be due to faulty charging port. I ordered new usb flex cable spare part from aliexpress and got it replaced . But still the same problems . Slow charging, usb not recognised
I am also attaching images of flex cable, charging cables
Please help me know what could be issue and any solution to this?
Is there anyway to flash stock recovery without data cable

I have the same problem.
Can anyone help me ?!!

Hi, You don't have the box ticked in the battery screen do you ?
the one that says
When device is turned on, do not charge the battery when connected to the PC
this should be unticked.

Hi Dean
Now I dont have it ticked !!
Any other idea's?
The problem could also be your usb line or usb port. try some alternatives first.
Tried everything, different usb leads, different sockets even different laptops !!
Help
Same problem here. But i changed the USB cable and problem solved. Did u tried it, with the official USB cable from HTC? (I guess so, just to check)
Yep I did !!
Will try again when I get home though..
Thats strange... my TP came with UK power adapter, so I couldnt use AC power until I get an adapter (4 days)... in these days I always charged via USB (all night long)
Well I tried the official usb lead and it charged last night, Im now using the official lead again using same laptop and same usb port and guess what !!! It wont charge again

Hi,
this is sounding kinda weird..
What kind of wall charger came with the phone, mine is a wall adapter that i plug the USB lead into to charge the phone
So i know my USB lead works as this charges the phone with both the adapter and via USB on any PC ( i have tried home and work PC's)
Sounds like it could be a handset issue then ???
mine is a Vodafone handset that i bought unlocked and flashed with a different ROM and its working fine..

Laptops can be a bit funny about USB charging, I remember one laptop I had wouldn't charge my phone (SE K800i at the time), unless it was on mains power. The laptop had to be powered up while on the mains, with no USB devices plugged in, then it would supply power to the ports.
My work laptop is also a bit funny about it, I had to disable powering down of the USB ports otherwise it won't power them back up, but since if nothing is connected there's not much of a problem. There is also the possibility it's powering the port, which will charge the phone, but not enough power to actually make it worthwhile, you can check to see how much power is going to the ports by looking under device manager. So you might want to check it's not a problem with your laptop.

This is exactly what mine turned out to be. At work I've got a Dell Optiplex 745 tower and none of the USB ports put out enough power to charge my phone and have the phone on. I've got wifi turned off but the data, EDGE, is always on. If the display is on and I'm in Storage mode there's very little charging going on. It doesn't drain quickly but it definitely isn't going up. If I'm in sync mode it drains pretty quickly and it seems as tho it's not even charging at all.
What I do now is plug it in at work and turn off the display. Kinda sucks but I need my phone fully charged at all times.
I have the same problem....
the usb and the factory usb are different if u have looked carefully
firstable, the shape of the heads are different. secondly, there are 4 pins inside usb and 6 pins inside the factory usb...I guess that's the problem.
Try messing with the USB to PC settings. I know my TP was acting funny and not charging, and after i disabled network functionality, i think it started charging. GL.
Thamks for all the replys, if done everytjhing sometimes it will charge sometimes it wont, I have it connected to my laptop all day for internet sharing, it has charged up very slowly twive, and not at all 8 or 9 times, same usb slot , laptop plugged into mains, official usb lead used ( it never charges from another usb lead )
This is the 3rd htc Ive owned and the first to play up like this over usb !!

Have you tried it plugged into a desktop computer? It would rule out the laptop being the problem if it didn't work. You could also use a mini-usb cable, which could also prove if the official cable is a problem.
Having similar problem...
I'm having a similar problem. My laptop used to charge Touch Pro when i connect it. Now for reason i noticed that it doesn't anymore.
I could be wrong, but I thought I read in the manual that when the phone is synched to a PC, it only charges in trickle mode, so it doesn't recharge the battery efficiently. Is this the problem?
same problem here. Mine was working fine with ANY charger whether it be USB, car charger or wall charger. But now it will only charge with the htc plug but not the HTC wall charger. The plug is the one with the ports for tv-out, headphones.
I'm going to go try and do a hard reset.I dont understand what could cause this.

S6 only charges when phone is off

So a problem reared its ugly head a few days ago...
I tried to connect my phone to my PC to transfer files, but the PC wouldn't detect the phone. It wasn't charging when connected to the computer either. I tried different USB cables and different computers - same problem. If I turn the phone off it suddenly charges, which tells me the USB port on the phone is working. I also tried different chargers too.
My device is rooted, so I thought it may be the ROM I'm running. I wiped the device and flashed another ROM, but still the same problem persists.
It seems like a firmware issue to me as it charges when the phone is switched off. I hardly ever use the USB port on my S6 as I usually charge wireless. I tried cleaning any lint and dust out the port too using compressed air and a toothpick - it didn't help.
Does anyone have any idea what the fault may be?
Are You using USB 3.0 port? Cause I had the same problem. Usb 3.0 never recognised my device. Now after I flashed 6.0.1 the problem is gone.

Tried on USB 3.0, USB 2.0 and a power brick, Mac and PC - all the same result.
Similar Problem
I have similar problem too. My phone is Samsung Galaxy Alpha. Yesterday, I charge my phone using Pineng Powerbank and then i notice that it show the lightning symbol but the battery is not charging but decrease and my phone become too hot. Since I don't bring the charger, I'd try to connect with different USB cable to PC and the problem is still the same. Then I remove the battery for few minute until the phone is cooling down. After switch on the phone again, my phone quickly heating up but the battery is normal. I'd buy new battery for replacement but the problem still occur. My phone also is not charging when in safe mode and only charging when it is turn off. Then I made a factory reset and it's work. Both of my battery is working too. What is actually happening? Does the powerbank is the culprit or virus? Thank you.

Honor 8 Charging/USB Connection Issue

Currently i am dealing with an issue with my Honor 8 which deals with fast charging and connecting the device to a PC. My device takes between 5-8 hours to charge, i've also tried another Honor 8 USB Type C charger which belongs to my friend. And It's still not working. It also won't connect to any PC. It always shows that the device is not recognizable and or has malfunctioned. Funny thing is that i sent it in for a Warranty Repair which once i got back, still has the SAME issue!! They "Claim" to have changed the USB Type C Port, Battery, and Charger with USB Type C cable. Spent plenty of time on the phone with Huawei trying to find a solution but i'm not getting a great solution. They escalated the situation to "Higher Up" after i spoke to a manager (Second Time) to see what else can be done. I'm thinking motherboard kinda fried a little one day while charging?? Some hidden Toggle within settings to enable fast charging and PC connection?? Anyone else having this same issue??? This happened out of nowhere as well. One day working and the next Issues everywhere! Sorry for the long Rant. But i'm still wondering if someone has pr had the same issue or kinda the same issue. I can't be the only one with this issue.
Sorry to hear but this happens to the best of devices.. At least Honor/Huawei are investigating the problem. But I would of thought they would conduct a test on your phone when it came in and again before sending it out to you. Still they would have to put on their jig and run a full test and or ship your out a replacement device.
i would suggest you to give it and get back another device from service center.. i think , you got a faulty unit.. bad luck..

Yeah, if you have just received your device then I'd send it back to Honor and request for a replacement unit. As yours could be faulty. However if you've had it for more than 14 days then you will have to send it back to their Service Center for repairs.
Another with the same problem here...
I bought mine from a guy (second hand) at a very good price. The Fast Charge never worked and when I connect to a computer I have the same problem...
The weird thing is that if you try to charge with a power bank or a USB from a computer or laptop it charges very fast... Very. But to the AC power it takes ages. I also try with the Charger of another guy and in a shop and never have Fast Charging... Don't know what to do because for the rest the cellphone really work well.
Same problem as above. USB charging seems to work fine but AC charging is unbearably slow (50-300 mah, 10-20 hours to charge). Running stock rooted Emui 4.1. I've tried factory resetting, unrooting, relocking bootloader, rerooting, and flashing backups from when it was working and nothing seems to have made any difference. Since USB charging works normally I hope this is just a software problem but Honor needs to look into this.
The "device is not recognizable and or has malfunctioned" sounds like you're using Windows 8 or later, so the OS should have USB 3 support baked in. Did you install HiSuite and the driver for the Honor 8? Although it's a USB type C connector only 2.0 transfer speeds are supported, so if you've got a cable with a standard USB connector data connectivity try a 2.0 port. Are you seeing any Unknown Devices in Device Manager? And is the Phone showing up?
Also, now that I'm thinking about it, PC data connection is turned off by default and has to be turned on everytime you connect the Honor 8 to a PC. There's a prompt that pops up under EMUI 5.0, but I think you had to manually change it from Charge Only to MTP/Device file manager Mode.
Fast Charging with an AC adapter only works with the charger that comes with the Honor 8 (or other Huawei phones that Fast Charge at 9V/2A). Qualcomm Quick Charge adapters will only charge at regular speed (probably 5V/1A). If you use an AC charger from an old flip phone or something a lot of those are only rated at 5V/150mA and might not provide enough juice to keep the battery from depleting if you're using the Honor 8 while charging it (and take 20 hours to hit 100%).

I am using the charger included in the package and its not working properly, also I tried with other Honor 8 Adapter that worked on my friends Honor 8 and is not working on mine. Also tried on My aukey Quick charge 3.0 compatible AC charger and is still slow as *****. If It is connected to acomputer USB charges faster than to the power line so i assume is a software problem or bug that do not detect properly the power any solution?
Can not send it back to Huawei because I bought it as second handed...

The EXACT same thing happened to me! About a week ago, my phone just stopped connecting to the MacBook. I then tried it on my windows computer, at work, and still, nothing.
I've been through the settings and changed everything and yet it is still not recognised by a computer.
My next option is to do a factory reset with the phone but I am determined to not do that as I don't want to lose so much data.
Did you resolve the issue?

Unfortunately I did not, Huawei would not do anything else, claimed to changed parts and nothing fixed the issue. So I sold my device for 80 bucks. Did you use any new chargers, car chargers, or change usb cables? I used a car charger with quick charge and a new us cable. Was charging my device while driving and noticed my phone was extremely hot. Must of unsoldered something on the motherboard.

Well I'm currently using a cable I bought from Vanguard (Shenzhen, China) and it still works now. One thing I have been doing is gaming whilst charging. The phone seems to feel hot but I didn't expect it to do this. I'm guessing the same thing would have happened if I'd been charging with the original wire which I keep at work. The constant use must have damaged it. :good:
Hello guys!
I have the same exact problem with me honor 8.
Takes forever to charge via DC and I cant access phone storage via use cable when connected to PC. I have bought and changed loads of USB cables but the problem still persists.
Anyone please help before I go crazy and ditch the phone !!!
I'm affraid there is no solution. I sent my phone back to repair centre 3 times with this problem. (No fast charge and PC not recognise. They replaced the mainboard at the end. It solved the problem for 2 days and dead again. I just gave up and living together with this fault however it's bloody annoying especially when you would like to download your pics and videos. :crying:
I have exactly the same problem, as described, with mine. It happened out of nowhere as well.

Fast charging not working

Yesterday morning, the Fast Charging worked ( I have an original Fast Charge adapter and a Baseus cable and i was charging with it with no problem until now)
That same afternoon I took the phone to replace the camera window(not the whole camera just the glass on the front; there are no signs of opening the phone)
In the evening I put the phone to charge and it writes that it takes 6 hours for full charge up to 100%
I was replacing adapters, cables- showing the same(approximately 6 hours).
I went to 3 stores, wanted different adapters and cables and still shows the same-USB charging,
My question is if anyone has an idea what to do in the situation because they told me that if I had to change the USB port or the battery, the phone should be opened.

Just broken USB-port... Some pin's from FastCharging are off so phone will show you is USB charging or just normal charging depend which pin's are broken USB connection (MTP for example) works good?

Nope...Even this isnt working...I have to transfer files over Wi-Fi...My PC says that it cant recognise the device even with installed Samsung drivers..So yeah I guess it has to be broken USB-port...
Fast charger not working because of:
1 you installed custom kernel
2 bad custom rom
3 bad cable
4 bad usb phone connector
To make sure you have good ROM
Flash the right stock ROM...then take it from there...

Yes. So more then for sure is broken USB-port...
I have the same problem. No fast charging and no connection to PC. This worked before and both abruptly went bad. I figured it was a bad phone connector port/jack and replaced it with a new one. Still doesn't fast charge or connect to the PC. Tried many cables also. Most be a software glitch. This has been driving me crazy for a few weeks. Can't figure it out.
To add, I did try to connect my phone to a fast charging car charger and noticed it wasn't fast charging and then I brought it in to the house to charge it normally to see if it was fast charging and it wasn't. After plugging it into the car charger, no more fast charging anywhere. Like I said, I changed the charging jack board in the phone and still not fast charging or connection to PC. Both had worked previously.
I have the same problem too, 6/7 months ago suddenly fast charging stopped working and no connection to pc. I have to mention that i have stock firmware, i never had a custom one and tried lots of usb cables pcs etc

Mate 8 Fast Charging No Working and Not connecting to PC

Hi, I have Huawei Mate 8 NXT-L29 (Hong Kong Version). A couple of weeks ago, I started using Magnetic Charging cable for my mobile. The cable worked great until I realized that after few days of using that cable, my phone stopped supporting fast charging. Not only this, I have not been able to connect my phone to PC for data transfer, although it still supports charging but very slowly. Moreover, my original Huawei charger and cable are no more supporting fast charging or computer connectivity.
I took my phone to service center which first suggested me to replace the charging socket which I did but it did not solve the problem. As a last resort, I had the complete charging circuit to be replaced and the problem is still there. I have reset my phone twice even have cleared the cache partition from boot menu. But all in vain.
I am posting my problem here, hoping that I will find the solution to my problem. Any help will be greatly appreciated.
