[Q] USB connection not working

Hello everyone, this is my first post and it´s about my Defy, which, for some reason, the USB port does not work to access the phone and/or the SD Card.
1: I did a soft and hard reset and the problem persists.
2: The phone does not show up on the device manager under Windows so not even an error message saying "Device not recognized" or something. Also, it won´t show up in Ubuntu.
3. The "Connect your charger" message shows up all the time.
4. No notification in the phone when plugged to the PC .
5. Even though I can´t access the phone from the PC, I still can´t charge it through the USB port.
6. I can connect/access the phone and SD Card using Wi-Fi (Motorola Phone Portal) but not USB. I can see "Plug in USB to launch" in Phone Portal but cannot press the button, only the one referring to Wi-Fi.
PS: This is my second Defy, the first one got the same problem so I got a new one... sadly, the it happened again.
PS2: I wonder if a USB 3.0 port has to do with anything? It´s the only thing that I noticed before the USB stopped working.
Any help or hint is greatly appreciated.
well, i don't think it's an usb3 problem ...
to be sure you could try to connect your phone with an older usb2 port computer ...
is the phone charging on wall charger and usb-cable ???
if not, it really sounds like a hardware failure ... then i would send it to customer service and tell them that there is the same problem again .. maybe the just repaired something and it's faulty again ... be sure, that they are changing the faulty things ...
if your phone is charging on wall charger, it could be that it is an problem with your pc ... try another one ...

1. I mentioned the USB 3.0 port because it was the only common thing just before the usb conection stopped working.
2. The phone charges normally using the wall charger or usb (2.0, 3.0) cable through the PC.
3. It does not matter what PC is connected to or the OS (Ubuntu, Win7)/
Thanks for the response!
It is possible to brick it. Wtih some phone's it seems to be a common error for usb ports to be blown.
Could also be the cable... My cable that came with the defy was already snatched after a few months. My screen started going on and of when I was charging it.

Is there a way to check for faulty hardware-related issues?
just test different cables, computers or even mobiles ... then you will see, what is faulty

What I meant was some software that check or even some kind of physical device.
Anyway, I know it´s not the cable or PC faulty but the phone itself. But I want to confirm if it´s software or hardware related and if there´s a fix.
Thanks!
Try using USB with logcat open. You might see something in the log that will tell you what's happening

N910c Charging very slow on PC

- Tried on All my PC's USB Port ( both USB 2 and 3 ports )
- Tried using Original Samsung Galaxy Note 5 Cable
- Bought and tested Aukey and Anker USB cables from amazon
- Bought new Original Samsung Note 4 Battery
- Charges around 2-4% an hour @ PC , so download an app "Ampere" , it states that i'm only getting around 80-120ma
- All cables works perfectly fine on the power outlet.. both standard and fast charge method
- Data Transfer is also fast
So my PC is probably the culprit ? but all other USB Devices works fine ATM

It's weird i know but you trying the usb cords. like you said pc, any major dust build up in the ports i have seen issues like this but just cant remember what the fix was.
You aren't going to get the fastest charging speeds when charging your mobile device via a computer's USB port.

Really? I didn't think you could. I know for a fact that fast chargers have the ability to charge a device using a higher voltage and amperage than a regular charger. I didn't think that fast charging via the USB port of a computer is possible.

note 4 version not connecting to computer or fast charging

ive replaced the usb port, fully updated the phone, tryed a friends battery, new charging brick and cords , tryed different
outlets and the phone will not fast charge or show up on the computer/any computer.
when i plug it into the computer i get a error message:usb device not recognized or malfunctioned (i shortend it)
much help needed please and thank you
With regards to the fastcharging part, are you also sure you are using an adapter that supports 2Amps at 5V ? This is also the spec of the original adapter that came with the phone (I also found that it works with different 2.1 Amp. adapters generally for tablets)

I have the same problem. I changed the USB board but the problem was on the motherboard. I test all possibilities soft and we did. I changed USB card, USB cable and nothing. I went to a service and said that it is guilty USB chip on the motherboard. True or not I do not know but the man said he changed and now it works. It cost $ 50. He said it's a motherboard intervention more difficult.

My nexus 4 when connected to PC it's only charging...

USB connection problem
No change in device manager happened even in fastboot mod, it's only changing, I test a lot of way for solving but no ways help me, if there is a solution, tell me. Thanks
Sounds like the USB port needs to be replaced on the phone.

can u explain more
I'm sorry Guy's, but I have to go for a monthly, but thread is open for your comment and solution!
There is an internal ribbon cable that connects the USB port to the motherboard.
I believe this internal cable needs to be replaced if trying different computers, USB cables, and USB 2.0 ports doesn't solve the problem.
I fix my phone problem, a repairman change my micro USB socket.

USB Type-c port : bugged or broken ?

Hello guys, here is the bug I experience
First of all i'm sure the cable isnt guilty as I tried two different cables, with one of them being new, getting the same result/bug
Whenever I plug something to my usb type-c port, it can ONLY and ONLY charge !
When i plug the phone to a PC, it won't recognize a phone is plugged ! It charges, but I don't have the window where u can choose between MTP, Charging,...
Of course I have enabled : USB Debugging, and switched from "Charge" to "MTP" in dev options
Even the USB otg doesn't work (with "OTG stockage" enabled ofc)
From times to times I could connect the pc to the OP5, but by plugging / unplugging the cable like 20 times... And now it's worse as it doesnt work at all !
It used to work perfectly in the past , is it possible the system can bug to the point this bug appears ? Is the type-c port broken ?
I have the same problem, the USB port can only do slow charging. It doesn't connect to PC/Mac and doesn't dash charge either. Taking it to service center as i'm pretty sure it's a hardware issue with the USB port.
Try downloading OnePlus USB drivers on pc you connected device to. https://www.androidfilehost.com/?fid=673368273298966498

MTP should work without those.
No it's not an issue with the drivers. The phone used to get detected fine and would do dash charge properly earlier, it suddenly stopped working.
I visited the service center, they confirmed my suspicion, it was an issue with the USB port module. A hardware issue where some of the pins on the USB module stopped working for reason, and as a result phone wouldn't receive connection from the cable. They replaced the module for me and the phone works properly again.
