[Q] PC Not Recognizing USB as Mass Storage

I'm currently on DK28 and anytime I plug my phone into my computer via USB cord it just shows that it's charging. This is an issue since I would like to switch to EB13 and I need to be able to use Odin for the EB13 modem. I've tried uninstalling and reinstalling the Samsung drivers several times and not just on this computer, on two others that I have. I've also tried multiple usb cords and it's all the same thing. I've Googled the problem and everything I've tried has been useless to me, including the PDANet thing. So my question is is there any other way for me to be able to update to an EB13 rom without having to connect via USB? Or does anyone have any other ideas as to how I can fix this? I've been just using a microSD card adapter to put things on my SD for awhile now so that's never been a problem but I can't use Odin unless my computer recognizes my phone I guess.
HELP!!

Have you gone into settings, applications, development and unchecked USB Debugging?
I also have read numerous times where people have found the USB connector on the phone had something bent and was preventing a full good connection.
Good luck

You have got to be missing something drivers can be 32 or 64 bit make sure you have the right one for your computer. Is usb debugging checked in settings/app/development. Randy Shear has alot of step by step stuff for on youtube that might help

Yeah I have USB debugging checked and my computer is 64 bit which is also what my drivers are.

Turn off anti virus and dl driver again thats what I had to do. Reboot both devices also

UN checked?? if it is checked, you can't use mass storage

Tried that too and apparently that wasn't the problem. :\

I read where one person who was having something like this was told to turn their computer off; plug in the phone to the usb and turn the computer on and it worked.
Maybe try that?

I've had this problem, got real annoying after a while. I ended up reinstalling the drivers and turning off usb debugging and it would go into mass storage. Re enabled and tried again, and it continues to work.

Thanks for trying to help guys but unfortunately neither of those things worked either.

I had this problem. I flashed a different ROM (try downloading a new ROM from the phone) then flash it after following the appropriate instructions.
The ROM I had that problem with was Nebula ROM, I fixed it by flashing Bonsai v2.0.

Well I have now tried that as well and even that didn't work. This is so ****ing annoying.

Try flashing another ROM instead of Bonsai. I hate that you're stuck, but I'd try a few more ROMs before giving it to a Sprint Store.

I had this problem as well and did everthing mentioned here as well to no avail.
Now here's what worked for me.
First, install drivers on another pc (ensure that you connect, wait for drivers to load, disconnect and reconnect your phone at least twice..sometimes a takes a couple of connects to install the drivers fully).
Next use odin to flash DK18 stock firmware. When you connect your phone..suddenly mass storage will be back again. You can then load whatever firmware you wish.
This has worked on my phone and a friend's with the same issue.

I had this happen to me on 2 different machines:
- First time: A restart fixed it
- Second time: My phone didn't like the usb ports on my work laptop's docking station. The cable would only work with the actual laptop's usb port.

"USB Device not recognized" - Tried everything I could think of / find

I've recently run into a problem with my phone being recognized by my computer... basically it just doesn't work anymore. This happened after upgrading from Midnight ROM 5.3 to ACS Frozen 1.2. At this point, when I plug my phone into the computer, it only charges and does not enter into usb connected mode. On the computer I get a pop-up message saying that the USB Device is not recognized. After searching through these forums and others, I have tried uninstalling / reinstalling drivers, installing PDANet, switching USB ports, and Switching USB cables... All multiple times. The best I've gotten out of the process is immediately after certain tries, I am able to get the usb mode activated, but only once. When I try to boot the phone into download mode because I'm trying to upgrade to EF02, it is no longer recognized, and then when I do a regular boot, it is still no longer recognized.
Any help would be appreciated.
Thanks,
Greg

I've also toggled USB debugging multiple times...

Which OS is your PC running?

Try downloading the android sdk and updating all its files and repo's? I had to do that for my w7 x64 pc to see my epic
Posted by some phone named the Epic.

Your drivers crapped out or your cable is flaky. Try a different cable. Also turn on USB debugging and go into Device Manager in system in control panel. Go to the unknown USB device (may say Samsung Android) and hit update driver and let it search Windows update for drivers, will take a long time for all the drivers. Then reboot and should work.

Are you using the cable that came with your phone? Mine stopped working and I had to buy a new cord off amazon.

Win 7 x64 is the OS...
I've found a temporary workaround by pulling the battery, plugging the device into the usb, starting it into download mode, and then replacing the battery, but thats not really practical for storage purposes, only for the one time install of EF02. I have used 4 different cables and reinstalled the drivers multiple times. I am going to try reinstalling the sdk and see if that helps, as well as searching drivers using Win 7 Device Manager.

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...

[Q] Can't connect to the PC

I have had issues connecting the Note 4 to my PCs. I have tried multiple cables and computers. A usb error appears "Usb Device not recognized" "The last USB device you connected to this computer malfunctioned and WIndows does not recognize it." All PC's are running windows 8. I have tried connecting it via fastboot to flash to stock as well as through ADB and I cannot get anything to read the device.

Are you using the oem cable? Sometimes cheap generic cables give errors. Enable usb debugging and see if that helps. Good luck.

Thanks but I've tried multiple. OEM and aftermakert cables. I found that when I put it in the charger it doesn't detect it as AC. I believe for some reason when the phone is connected to the PC it doesn't switch to MTP, which could cause the issue. I have wiped the phone, tried different roms, and installing plasma kernel. I am at my wits end. I have tried finding sprint's seceret number to dial, supposedly there's a menu to force MTP but I can't find it anywhere.

OK. So I couldn't connect via cable I tried flashing the stock image though mobile odin and now I lost recovery and the phone bootloops. Does anyone know a way to boot into recovery from the external SD card?

I would just flash the OF5 tar and start from scratch. http://forum.xda-developers.com/not...om-sm-n910p-stock-of5-odin-flashable-t3158114

Sounds like it's your computer.
Edit: Any other phone's Samsung or not able to connect? Does your phone charge with any or all of your cables? Hopefully the stock cable.

You need to go to Device Manager and Uninstall/reinstall the drivers pertaining to USB
Uninstall the samsung drivers
After that, unplug your powercord from the laptop
connect the phone to your usb port first and then replug your powercord and turn on your laptop
let the usb and samsung drivers reinstall(auto or manual)(if it detects it normally))

I was able to get my Note 3 to connect with no problem, I was even able to get ODIN to detect it in Fastboot. I have one more cable I am going to try tonight, I have my girlfriend bringing it with her. I may have switched an S4 cable with the Note 4 cable. I hope this is the case.

I was using my desktop, and I tried this on my laptop. Didn't work. Thanks though! I am wondering if this possibly could be a Windows 8.1 issue...
Anyways, 5.50 to anyone who gets this working.

I accidentally switched cables with my son's s4 and nothing would work. Figured it out and then I could connect to my computer. Could be the same thing lol.

I wish that was the case. I am wondering if it's a windows 8 issue now.

I'm on 8.1 pro, and my devices detects fine under cm12.1.
Have you tried going into Settings > Storage. select the 3 dot menu on the top right and force MTP or PTP detection while device is connected to PC / Laptop?

Oneplus 3 does not connect to pc

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:

Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?

i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?

What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!

I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.

Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!
