Hi
I seriously need your help. I can't copy files from pc to my sm-a9000 anymore. I did nothing like rom flashing or system modification yet. One day, the pc just don't recognise the phone, even in download mode. I tried differents pc, differents cables and ports...nothing. i tried *#0808#, drivers reinstallation, nothing... when i connect the phone, the pc display "unknown device code 43" and the phone just get charging. When i use an usb drive, the led just blinking and the phone don't notifies the connection. I use the hong kong 6.0.1 stock rom TGY a9000zhu1bpi3 an it's not rooted
Seems like you have a hardware failure. It may just be the USB port itself has some bad connections to the PCB.
I have repaired several USB ports due to issues like this, but it's very difficult if it's soldered to the PCB.
If it's modular like many are nowadays it's a simple matter of swapping the usb port out.

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

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.
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.
Whenever I try to hook up the Zenfone 5 with my PC, I get the "unknown device" error, and Device Manager shows me the error on the topic: "Unknown USB Device (Device Descriptor Request Failed)".
I've tried just about anything, and nothing seems to solve it... Shut down/restart the PC, try a different USB port, remove power supply, etc...
Ah yeah, phone has access to bootloader and TWRP, but even in these modes I get this error when trying to connect via USB. Already tried different cables and different computers.
1) sorry for my english
I having this issue today too. but in my case it is the USB cable damaged and the conector on phone too. i changed the cable and open my phone and squeeze a little the conector USB and the problems solved. the stranger thing is when i conect my usb cable on usb 3.0 on pc the pc going crazy but i don't connect my phone on the other side. i think my cable is gone :/

that's sad... here I could test both my USB ports and cables with 2 other phones: they're all working nicely. So now I don't know if my problem is the USB connector or the whole south board. I did try changing it with another ZF5 I have around here, and it worked (and suddenly, that other ZF5 isn't being recognized anymore)...
Hey!
I can't connect my X Compact to computers.
I have tried different computers, cables and I've changed my phones USB port also. Still not working.
Is the motherboard dead? Should I try another port?
I could live with it, but I'd like to install Xposed. Would be safer to have a connection with the device just in case.
Thank you!

If there's no response at all from multiple different computers, seems like some kind of hardware damage - maybe just broken USB port... A phone fix-it shop should be able to fix it if you want.
Unfortunately as I said, I already changed the port once.
Should I change it again or could it be in the motherboard?
I didn't flash it after the port change.
