[Q] Issue with USB Mass Storage

Last night I was getting ready to do my first root. Was watching the syndicate video, following along.
One thing I noticed last night, is when I plugged the phone in for mass storage, to copy the files to the sd card, I kept getting these two errors.
First, when installing the drivers after plugging the phone in, I was getting this cdc failed. You can see it in this picture...

I also kept getting this "scan to fix" pop up for the M drive (my phone).
When I turned on USB debugging on the phone and plugged it in, it seemed fine, except I could not access the M drive on my computer, I would get this error...

I did some search and decided to try what another user tried, I formatted the sd card.
I then plugged the phone back in, and did not receive the "scan to fix" errors anymore and could access the SD card with no issues, but I could not access it still while in debugging mode.
Is this by design?
Samsung drivers are installed. Got them straight from the samsung site.

No yiu should be able to play with your sd card wgile in debugging
Did you turn on mass storage after usb debugging?

I couldn't access the mass storage in USB debugging for a little while. It turned out my drivers got slightly corrupted. I could do everything else but that. Went into Control Panel with USB Debugging on and found the driver listed as samsung android in USB in Device Manager and hit update driver and let it get it from Windows Update.

I will try that this afternoon.
How about that cdc? Any reason why that is failing?

Same thing.
Says the latest driver is installed.
It never gives me the option of choosing charging, mass storage, tethering like it does when debugging is off.
Any ideas?

Ok, so I found this some other forums.
Seems stupid, but I had no clue.
With my phone, with debugging off, when you connect the USB, it asks you what you want to do.
With debugging turned on, it does not, you have to tell it. Below is what I found....I feel dumb..
"Okay, so if you are freaking out, or can't figure out why your new Epic isn't being recognized by your computer, calm down. Some of you are probably already searching for drivers. Ya I already went through that freak out when I got my Vibrant. Okay, to mount your phone, and have your computer recognize the internal/external memory, do this:
Connect your phone to your computer via USB. Give it a few seconds.
Next, PULL DOWN your notification bar.
Next, tap your finger on "USB CONNECTED"
You then get a message asking if you would like to mount. Tap "mount" confirming you would like to do so.
Enjoy, your computer should now recognize the internal/external memory."

I had the same issue with my epic, try using a different usb cable, the one for the motorola photon resolved all the issues I had with connecting to the computer, I found out thru experience that the stock cable when using windows 7 kept giving me the same error..

Also, I've had success with rebooting both the phone but especially rebooting the computer and plugging the phone back in. Try a different USB port, some folks have 2 SLOW USB ports for mouse and keyboard (mine are in the back lower left...the fast ones are on the right and in front). Most folks have better luck trying rear USB ports (although I don't know why). First, try the computer reboot though...

[Q] USB connection

Ok so I am trying to plug my phone into pc using usb cable so i can use odin. But my computer doesn't recognize my device. I've tried everything from uninstalling the drivers and reinstalling them restarted pc and phone. nothing works i did get it to read one time and was able to access my sd storage and then i tried to go into download mode and i plugged in usb cable and it didn't recognize so i got out of download mode and it didn't recognize the phone again. Then i plugged in my girls evo and it reads the phone all the time. Is there something wrong with my epic then? how can i fix that problem. seriously getting frustrated!!

Try not to double post. We will get to your issue eventually. Refer to the other case, as it has potential solutions available for your issue.
(I've dealt with this as well.)

flashed ICS rom now phone cant be recognized by computer

ok basically phone wont go into mass storage mode when connected to computer and it isnt recognized by odin or the the computer at all and let me get all these out of the way before im asked
ok first yes driver are installed properly i even installed kies twice and just the drivers from the samsung website to make sure i wasnt messing up somewhere
and then...
i also tried doing a nandroid of blazer rom and getting back to the gingerbread just so my phone would be recognized that also did not work
and then..

ive used the original USB cord and the one i bought to day as well as several different computers just to see if the pop up as recognized with show but nothing happens my phone seems like its no longer capable of going into mass storage mode
and then...
moved this here hoping someone has has this issue hopefully you guys can help ill be up all night so feel free to resond whenever thanks guys

make sure your phone is disconnected from the computer and then try going into the settings and in the top section that is wireless and networks press more, then USB utilities, and press connect storage to PC and then plug your phone into the computer. had about the same problem and came across that.

You can also try going into your device settings on your pc (samsung/modem) and resetting the driver it seems to get "stuck" sometimes.

+1 to this... its the new way to connect

I put this on my sd card (by taking the card out of the phone) and putting it in a card reader. I flashed the file from the stock recovery and this gave me custom recovery. Then I restored my previous backup. I was having the same issue and FB21 has too many bugs. I went back to gingerbread but kept fb21 modem.

You can actually get MTP working quite simply...

To use USB MTP you have to unmount SD Card first then plug in.

Did this and that got my computer to acknowledge I had connected my phone but not it says unrecognized, so I'm going to uninstall kies and then reinstall again and see if that helps

What ROM you running, that might help ..... maybe turn off ADB , in settings, and check usb storage there ...

no ROM, everything is stock and debugging mode is unchecked as well
when i mannually try to use the USB mass storage from Setting>Wireless>USB utillties and click on Connect Storage to PC it gives me a window saying "ATTENTION: Usb is connected. Remove the cable" when i remove the cable then it tell me to Connect the USB cable

Same thing happens to me.
My solution is to plug my/your phone to the computer and open the notifications. Click/press on the usb is connected notification and you can enter storage mode directly without hassle.

When I had this problem, I just needed to fix permissions in recovery. Is the phone rooted? Did you recently buy it new or used?

Solution is simple I suppose.
Disconnect the cable.
Go to settings from where USB connection can be enabled.
Click that option and it will ask you to connect the cable.
Only then connect it. That should be work.

Windows won't recognize t989

Hello all!
First: I promise I searched the forums and google as hard as I could!
I'm running AOKP JB with CWM, although the problem was present on stock ICS from T-Mobile.
Symptoms: Computer and phone will refuse to acknowledge any connection (nothing shows up in Device Manager), except the phone will still charge. If I do the "remove the battery with USB plugged in" trick, the first time I do it, it will recognize an unknown device, but kies and adb won't recognize it. If I unplug it and plug it back in, it'll go back to not acknowledging any connection.
I previously programmed it (when I was still running stock ROM) via ADB via WiFi, but I need to be able to use ADB via USB. Besides, I can't seem to get ADB over WiFi anymore.
When I plug it into a different computer (Win7), it will, however, recognize my phone.
Earlier this year, before I ever tried programming via WiFi, it connected to my Win8 machine with no problem. I don't think it's a problem with the wifi setup though because the ROM was reinstalled and of course I've restarted ADB in USB mode in the months since...
What I've tried:
Reinstalling Kies
Reinstalling Samsung USB drivers
[^]Restarting the ADB server
Updating ADB
Trying different USB cables
Trying different USB ports
Toggling USB debugging
Toggling MTP mode
The UART thing from the dialer
Restarting the phone and the computer (of course)
Checking to see if my computer's USB drivers need to be updated
The android terminal command "setprop persist.sys.usb.config mass_storage,adb"
Pulling and replacing the battery while connected via USB
Crying in a corner
If anyone can help me, it'd be greatly appreciated! I'm all out of ideas and Google is no longer helpful =/

try to uninstall the drivers that are present anything samsung related to your drivers ... then connect the phone and let the process do its thing if you have the samsung drivers saved on your PC and the drivers still aint working update the drivers and then manually click where the drivers are to install them and hopefully it will work and when you tried MTP is it the only option it gives you no storage or anything ??... and is usb debugging on when you are trying all this ??

I tried on my work computer that didn't have any samsung drivers and when the "unknown device" dialog popped up it didn't do anything or install anything, nor did it show up in Device Manager. Unplugging and replugging it back in did not reproduce the dialog box. Togged USB Debugging and still no dialog box saying it recognized it.
The thing with the samsung drivers is that they're self installing so even if it popped up in Device Manager, I wouldn't be able to manually update the drivers =/
I tried MTP both with and without USB Debugging, although it also gives the option for PTP.
At this point do you think I should unroot and go back to stock? It's not been recognized on three computers now! =[

Are you using the stock cable? My computer wouldn't recognize mine without it.

Both the stock cable and a generic cable.

Similar problem
Similar problem as the OP. And hi guys, it's nice to be on these forums.
My device, when I plug it in using the stock cable, doesn't even charge. It doesn't show up in device manager, nor does it give me a notification, or say it's unsupported and bear that yellow icon. I have tried using different USB ports, I have tried the toggling USB debugging, I have tried restarting phone, computer, and taking out battery. I have tried that PDA/MODEM dialer trick. I am using 4.1.2 Jellybean, not rooted. (that WAS my goal,, until I hit this roadblock) I have not connected it to the computer in the past, it's relatively new. I'm thinking the cable is bust.
Any suggestions would be appreciated. It charges fine through a wall outlet plug, be it generic or stock.

so guys ive come to a conclusion i think its something in the samsung usb cables try getting yourself a blackberry usb cable , TRUST ME !!! ever since i got my phoness etc... tablet and yadi yadi samsung usb cables have always seemed to give me problems i think its because they are multi data/charging cables and when using the blackberry usb cable i have never ever once encountered a problem with any of my phones sd/storage problems do yourself a favor and pick up one of those cables and you will be golden !! if not then i guess im the only lucky one :LOL here you go http://www.amazon.com/Blackberry-Travel-Adapter-Micro-Cable/dp/B004VMVSYK/ref=pd_sim_cps_2 5 bucks!
Edit also one more test boot into recovery and click in the advanced menu and see if mount usb works for you in recovery mode ??

FIX (try using a generic cable)
I actually solved it on my own! After borrowing a generic cable from a friend it booted up! The Samsung cable was just not doing its thing.

yeah im telling you those cables they provide are JUNK!!! i only use my samsung to charge because they do that well but data they are str8 CRAP!! glad you got it up and going

OP
Hope OP will have the same luck as me...pray to the Android gods...
