When I Switch USB Debug(turn on or turn off) when USB is connected, the staus bar will show USB option(PC mode,USB mass storge,charge,etc..)
But no matter what I choose,It does't work.
And when I run adb command(usb debug on) , It shows "device not found".

I had changed ports ,and USB cable
And windows xp and win 8.
But It's the same.

are you using the stock usb cable?
are you running a rom?
what recovery are you using?
if you have a custom recovery hook your phone up to your computer and boot your phone into recovery either cwm or safestrap
go to mounts and storage and try to mount sdcard and see if that works
p.s
make sure usb debugging is enabled and check mass storage in the drop down

Was there ever a solution found? My droid 3 for some reason the usb debugging isn't working, the computer sees it and I can access my files, but debugging won't enable. I turned it on and off in settings a bunch of times and tryed a few different drivers

[Q] Broken Screen..

Hi everyone, unfortunatly i broke my screen, my phone was rooted and i was using CM7
i would like to recover my files, but due to the my broken screen i can't see anything so i can't mount usb storage,
I also heard that if i activate usb debugging mode i can acces my files easily.. but debugging mode wasn't activated..
and finally I heard that through Recovery Mode, i can mount usb storage, but once again i cannot see or do anything ..
so can you help me please ?
thanks a lot for your help, and thanks to everyone on this forum for their help and their roms etc !

AW: [Q] Broken Screen..
Search on google for a pic from the the right recovery version then you navigate blind witch the picture.
If this dont work you can force the into recovery mode and plug it to the PC. You can save your data using adb without enabling usb debugging

Hi thanks a lot for your answers, i think i was on cwm 3.0, i found some screenshot, and yes it's the same, thanks i will try it !
how can i save my data with adb without enabling usb debugging ?
thanks a lot !

Go into recovery and plug it to the pc. Open cmd and navigate to your adb folder. Then type "adb devices" you should now see your phone listed as some random numbers. If not you did something wrong.
If you see your device type this "adb pull /sdcard C:\…" and the whole sd should be copied to the directory.

thanks a lot !! with this method can i also save my contacts, notes etc ? thank you so much !!

AW: [Q] Broken Screen..
The contacts are normally saved with your gmail account.
With this command you push your whole sd to the pc but i think if you want also the app data you have to use another command and you need root.

MassStorage

So I recently installed ubuntu 12.10 and I want to connect the o2x with the computer but it is only chargin....how can I have Mass Storage like in windows?

What rom? It's difficult to help without any info

It should work out of the box, unless you have JB ROM. In that case, follow this:

Check if you dont have Fast Charge ON. Fast Charge have to be turned OFF.

I have Mivv's Unofficial CM10.1 Build beta 7 and Kowalski Kernel. I have PSP Fast CHarge turned off

I've got the app but when I'm mounting my device I get an error in terminal that permision denied and unable to initialize device

MTP or Mass Storage
1. First you need to be sure that the USB Fast Charge is switched off ( if you're using Kowalski Kernel ).
2. If you connecting using MTP, you will need some tools. Use gMTP. Either you can mount your MTP device as directory using mtpfs. Follow this instruction: http://forum.xda-developers.com/showthread.php?t=2055563
3. If you want to connect using UMS (USB Mass Storage), you need to switch it in Settings->Storage->USB computer connection (context menu)->Mass Storage. Or just select this method in stock firmware dialog. Then you need to reconnect your device and select usb storage in status bar.
4. If you have problem with all these methods, you can use ADB (Android Debug Bridge) to manage your files. Just enable USB Debugging mode in Settings->Developers options(switch it on)->Android debugging. Then install android sdk tools in your system.
Follow this instruction. http://www.xda-developers.com/android/installing-adb-on-ubuntu-the-easy-way/. Then use adb pop and adb push commands to manage with your content.
5. If you have problem with all of this method, you can use AirDroid application and manage your files wirelessly using Wi-Fi.

Have a good luck, mate!

I just needed to enable USB debuging. I enabled it and it solved all the problem

Hi,
I'm using CM 7.2 and I can't access any mass storage - phone > PC USB connection at all. Any ideas?

Boot into TWRP and connect to PC. See if you can mount MTP that way. Not a fix but could get your files transferred. Also may prove if more than a ROM issue.

I have the same issue? An it still is not coming up with TWRP? I tried the DEV M preview, it's good. But will not connect to PC as MTP?
Usb debugging off, selected mtp in dev options, reboot phone. works now?

I'm actually on stock rooted and unlocked, so idk what's up

Have you tried a different cable? Different USB port?

I tried different ports but the phone will connect adb and ptp so I assumed it was the phone. When I connect using mtp, it makes the connection sound but nothing happens.
