[Q] USB connection not working - Defy Q&A, Help & Troubleshooting

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

Computer reboots/BSOD when connected to USB

Hello there,
Running an O2 XDA Mini S stock ROM with ActiveSync 4.1 on a Windows 2000. Initial ActiveSync went without a hitch, with the mobile able to sync with exhange server nice and smoothly. Then later on, whenever the phone is plugged into or unplugged from the USB data cable, the computer just reboots.
Are there any known issues with this? Could it be a problem with the USB drivers on the computer or the ports themselves? The phone developed this problem whilst plugged into an externally powered hub, but plugging the phone directly into the motherboard USB ports produced the same problems.
Thanks in advance,
Andy.
EDIT: I've attached a CPUZ report of the system so you can easily see the spec of the computer.
It's possible that your phone conector are damaged and makes a cortocircuit when you connect to the cradle.
Try whitout pluging the power in the cradle, only connecting to the usb port of the computer.

That could be a possibility, but not using a cradle here, just USB Cable.
Try deleting all of the USB controllers in Device Manager then rescan to pick them up again. resolves a multitude of USB problems

Just tried that after reading your post, no dice Thanks for the help so far though
if u r using a firewall , either disable it or delete it all to gether
i had the same problem with sygate personal firewall
If you have Kaspersky AV, download the newest version on the kaspersky website! It's not a very good idea to uninstall or disable the firewall.
Thanks for all the help guys, definately gave us a few extra things to try
Just to update the thread in case anyone comes across a similar problem in the near future;
After exhausting every possible Driver reinstall/upgrade/reformat we have come to the conclusion that it's faulty hardware (USB related) on the motherboard, so will be transferring the PC out. The PC in question is a good 5 years old and it's the MD's, so he was due for an upgrade in the near future anyway

Please help! Note 3 wont stay connected to comp via usb!!!

Hi guys, I have this really weird issue occurring. I have my note 3 connected to my computer via usb, but it does not stay connected. My computer keeps making a noise of new device connected, then disconnected. The phone connects, few secs later, disconnects. I have tried 3 different usb, 1 is the original,, different usb ports. It cant be the cable tho, cause it charges fine, and i wiggled it while charging. I let the drivers install when i first plugged the n3 in, so those should be good.
Any idea? could it be a ROM issue? Really need it to work, since I use tethering (

What rom are you using? And have you tried reinstalling drivers from samsung? http://www.theandroidsoul.com/galaxy-note-3-drivers-installation-guide/ and have you tried just using the micro USB cable (not the USB 3.0)
biggins 4.5, yea i tried those drivers, didnt try usb2.0 yet.
Its literally sitting here connecting, then disconnecting on and on, i have no idea, not even moving it

It could be the data pins in the cable/phone, the power pins would still let it charge even though there's still supposed to be energy going through the data pins when charging. And have you selected a different option when plugging it into the computer (from installer, media device, to camera) from the options that note 3 provides? (click the icon in the status bar when you plug it in)
yea i tried camera, its on installer by default i think and i tried mtp also, usb3.0 said it required airplane mod so i didnt try that. How could i check the pins>

Well it you look at the port and they're not bent or snapped then it isn't the pins. What about USB 2.0?
Will try 2.0 tomorrow, here is a pic of the pins, if you zoom in do they look ok?

What OS is your computer running? There are some USB issues with windows 8.1. I was having the same problem at times but there was a fix in optional updates that have seemed to clear things up for now. I think it's the download numbered...2914219. I'm not completely sure as I did a few weeks ago.
Just for the record, I have had trouble with certain cables in the past. Sometimes computer didn't like a long cable.
Pins are absolutely fine, only reason I even mentioned those was because one time a little kid plugged my streak 7 cord in upside down and jacked the female port to crap. And as TheAfroSamurai mentioned it might be your computer, I had trouble with a long cable with my kin 2. Different cable fixed it for me.

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 is not working to transfer data

Hi. Last month I forgot my charger somewhere and I endded up using another one that didn´t work fine.
my problem is that the usb conector only work for charging (turbo charging work too) but not when I try to connect it in my pc.
I already use different cables so I think I should change the usb port, but it could be something else? maybe the board is broken?

If you tried to connect your USB cable directly to the back ports of your PC, i mean, the motherboard USB ports (not the front ones), and tried in differents PC's too, looks like your charging port has been damaged.
Something exactly as you described happened to me in the Nexus 5, but in that case, just had to change a flex cable that contained the charging port.
Anyway, it's a very cheap part, and it's pretty common that the welding of the USB port get broken. You will have to send your device to a mobile repairs shop, or change the charging port by yourself (only if you have some knowledge using welding stations).
I recommend the first option because it's the most common break on a phone, and these guys in the shop must be very accustomed to repair this (it's not very expensive either).
try any other phone's data cable! :?
I've tried another cable and my computer connects but says the file is empty. I tried my old phone and I can see files. So I think there must be a setting on my Moto 4 that I need to change. When I drag the status line down I don't see USB or connect to camera.

Hmm, when you pull the notification shade down, do you see a notification about 'USB Charging this device' when your device is connected? If so, then what happens when you tap that notification - do you see a pop-up like in the linked screenshot? If so, tap the Transfer Files option in that pop-up and your device should re-connect and show the internal storage of your device.
If your device is in USB charging mode, it seems normal to not show files (as a security measure?).
