[Q] No USB Connection - Atrix 4G Q&A, Help & Troubleshooting

I flashed my atrix using RSD lite and unlocked the boot loader. Once complete the phone rebooted and everything works fine except when i plug in the USB it flashes USB Connection in the notification bar and then quickly disappears. It will not connect to my PC. The PC detects it and then says device unplugged.
I have tried 3 computers 2 USB cables - wiped cache and reformatted.
It still charges and when in RSD or fastboot mode it works fine.
Thanks in advance for your advice

To me it sounds like you need some drivers.

If you're on windows 7 it will automatically install proper drivers. If not, you have to download the drivers for the device to work properly.

I have the proper drivers. I have plugged another atrix in to the same PC and connected with no issue. It is only this device. It connected fine before I unlocked the BL

this happened to me as well, are you able to charge normally? if you are not able to then it means that you have the exact same problem I had with a atrix, if you are under warranty I suggest you try cashing it in as there is mainboard damage, swapping the microUSB port will not help, I think there is a fuse on pin 2 or something that is blown

The phone charges fine. And the usb works in fastboot and rsd mode. When i plug usb into pc it charges just will not install

I do have same problem with my motorola atrix 4G. How did you get it resolved ?

[Q] Can't connect the phone with PC using USB cable.

Hello guys, I recently bought an Atrix 4G from UK. The problem is that when I connect it with USB cable with PC (Windows 7 32bit) the PC recognize that the phone is connected but nothing appears on the notification bar on the phone. First tried with original FW 2.2.2 orange, after that rooted, unlocked the bootloader and installed CM7 but it is the same thing with it. I installed the latest USB drivers using motorola driver installing program from the official site, tried with other cable but nothing. RSD lite recognize it if this will help.. Does anyone know how to fix this issue.

Question for you.... do you have an micro sd card in the atrix? That could be an issue. Also, you can look at your computer's usb settings to see if your phone can be forced into usb mode that way. Just giving some ideas.
Yes, I have SD card, tried without it but the same thing - no notification on the phone and nothing happen on the PC except the sound of connecting a USB device. How can I force it in USB mode?

Try looking in settings of the computer for USB drives.
That's when I start exploring a bit in that area when stuff doesn't connect to my laptop.

Didn't find this function. Anyway the point is that the computer recognizes the phone but the phone does not show anything in the notification bar.
I just solved the problem :
1 - Turn off the phone.
2 - Turn on while holding volume up (RSD protocol mode)
3 - Connect the phone with USB cable to the PC, wait for windows to install the drivers, and disconnect.
4 - Restart the phone, and before connecting to the PC type in the dial box #5.
5 - Connect it with the USB cable.
I saw this advice from other forum.
I know it sounds stupid but this worked for me. Thanks anyway for the separated time.
Thank you
your advice saved my life
Lost usb connection with my laptop and home pc 3 days ago
Tried everithing you know what I mean
Most advices are for babies in kindergarten:
- bad usb cable
- wrong usb port
- usb debugging
- drivers
BS!
#5 really works / you need actually dial #5 with your phone app and then quick connect cable
I had the same problem ... I had to send it to motorola for warranty and they changed my mainboard!

try the usb ports in the back of the pc with the "original usb cable for the atrix
also if your rooted download a teathering app called pda.net install it on your phone and pc it will provide proper drivers for the atrix
at&t atrix's had to do this when we were on 2.2 and it sure does work!
Thanks!
Thank you for this! Dialing #5 made the trick!

Ooops. Can't enter recovery and ODIN will not recognize

For a while now I haven't been able to use a USB cable to my phone because "usb drivers not recognized"
Anyway, today I flashed the sept 3 build of AOKP and it flashed fine. I then went back to recovery and flashed devil kernel and gapps.
Now i'm stuck in a bootloop and cannot get into recovery. I normally would just odin but i can't use that as my computer does not recognize..
Help please?
Anyone?
I have tried multiple USB cables (not a genuine samsung one though) and have had no success. What could the problem be? My laptop says I didn't even plug something in, and my desktop says whatever I plugged in malfunctioned.
Download and reinstall the drivers. That has always done the trick for me.

After you redownload and reinstall drivers, put your phone in download mode and plug it into the wall charger first, then the computer again. I had to use a data cable that I got from Fred Meyers to get me out of trouble once also.

Tried reinstalling drivers a billion times and also tried entering download mode before computer. One thing I have noticed is that it say "USB device has malfunctioned" and it shows as "Unknown USB Device" when I plug it into a USB3.0 port, and when I try USB2.0 it doesn't show up at all.
It is possible there is something wrong with the cord, computer port, or port on the phone. Things happen of course. I would try getting g your files together and using friends computer for a few minutes, just to see if the phone is okay. Just using the process of elimination of course. Good luck!

The same thing happened to me one time u had to change usb cords then it was my ports and once I did one of those I was back in business

Chargin port its not working as a usb in the computer???

Hey guys today i got the samsung galaxy s2 gt-i9100 and the phone works fine but theres something weird happening and is that everytime i plug the phone to the computer it charges but it doesnt let me use the phone like a usb drive i cant acces my phone and in the notification bar it doesnt show the option to mount to usb, and if i put the phone in download mode odin does not recognize the device and everytime i plug the phone its says one of the usb devices attached to this computer has malfunctioned and windows does not recognize it.
Do you know what could it be? is this something than can be fix?
Before you can connect the phone via odin, you need to have the drivers installed. So first thing you need to do is have your computer detect the phone.
-See if the cable is working..if you have another cable, try your luck with that.
-clean the phone's USB port.
-try putting your phone into USB debuhging mode from the settings menu.
-Im assuming your still on stock. Dial *#7284# and on the USB option select PDA. This worked for me while I had trouble on stock.

Question about charging

Hi dears
I have some problem about charging. First of all I am using neatrom lite + jeboo v1f rebase. The problem is when I plug in my phone for charging my phone detects it few minutes later and same when I unplug the phone. Another thing is connecting the phone to computer by usb cable. Sometimes I can see my phone in my computer but sometimes my pc give error that unknown device connected.
What do u think about this? What could be the main problem for that. In my opinion my phone's plug area.

You could try and re-install the Samsung USB Drivers.
If that doesn't work then try to completely wipe KIES and the installed drivers from your computer and then re-instlling it from samsung.com.
That should work since Kies has had an update, but if it doesn't, then indeed it's the USB inserter in your phone (don't know what it's called ) which is the problem.

Bricked - Fastboot and not being detected by PC

Hi,
My phone just starts into fastboot after a failed setup. I'm trying to recover it but it isn't being detected by my pc. I've tried a lot of USB cables and it is not working.
Even without the properly drivers it should appear at Windows Device Manager, right?
It appears that it is a hardware problem. Before that I've been unable to connect it with my PC, and I've ordered a USB board replacement. I've aleady replaced it, but it is not working.
Thanks.
Try with a deep flash cable or disconnecting the battery and connecting it again
