[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.

[Q] Can't connect to Kies through USB tried several things...

OK, did a search in this forum for "Found New Hardware SAMSUNG Mobile MTP Device" as well as "connect to Kies USB XP" and other variations of these. I believe I have tried all suggestions that I have found, but advice would be appreciated
Firstly, I have a Dell mini 10 running xp that my E4GT connects to fine through Kies. My E4GT is running StarburstROM 1.9.5 with LoStKernel 1.0.0.8+EXP
My old HP pavilion, running the same version of XP however just says over and over "Found New Hardware SAMSUNG Mobile MTP Device" and the new hardware sound plays about every 5 seconds.
After a fresh install of the most recent version of Kies, I tried
Different USB ports
Different cables
Making sure no files have extensions longer than 15 characters. (or was it 16...?)
Recovering the drivers through Kies
Downloading and reinstalling/reapplying the USB drivers found in various links here on XDA
Uninstalling and reinstalling Kies
Going to Device Manager, right clicking on the yellow triangle of the samsung mtp device and directing the computer to install drivers from there
Still I get an endless loop of Found new hardware. Unplugging results in "a problem occurred during hardware installation...etc" Any thoughts I haven't tried yet?

Make sure usb debugging is not checked in settings/development/applications.

what? i thought usb debugging had to be checked?
and either way it shouldn't matter if the phone is in download mode, correct? maybe i am wrong. i would assume that since he got it to work on a different computer it is not a setting on the phone and a problem with the computer reading the device's drivers.

Yeah, USB debugging is off. Tried it with it on just for giggles, but no joy. I may just have to accept that it won't connect to that compy. Can't get it to connect to Kies or even connect just for file transfer. Had same trouble with my OG epic. Maybe something about the original driver install from back then....
I'll try manually removing all drivers associated with the device and see if a reinstall from scratch (again) will work. I'll also check the .net version again, but I think I already did that. Thanks all!

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...

Phone not Mounting on PC

So my phone was mounting fine on my pc, and then all of a sudden it wasn't. My Nexus 7 still mounts properly and accepts developer commands, but the m8 won't (yes developer settings is on).
I tried wiping and flashing a rom clean and it still doesn't work, charges fine though. Any advice?

Subscribed
I'm having the same issue. Stock non rooted and it will not connect. I have tried it on other computers cables ports everything.

You might try a different cord.
Open Device Manager in Windows and then plug the phone in. Do you see it in the list with a little yellow triangle? Do you see Android USB Devices listed?

OP after literally messing with various driver files, 8 usb ports and 2 laptops, I dug out my old box of cables and found a taped up, on its last limb OEM HTC EVO 4g (not lte the original) cable. This thing has been through the ringer. But its exactly what It needed. I figured with the 3 cable I had already tried this wasn't the issue, but have you tried using an OEM cable? I guess that is all that works. Good Luck

Still trying to get it to work, have tried 4 cables myself. I might just end up having to return the phone.... Fastboot works in bootloader

Uninstall all HTC drivers and HTC Sync. Then connect the phone. DO NOT choose the option to automatically install any drivers.
Open Device Manager, find the phone. Select the option to manually pick the driver, and select the generic MTP device driver.
This is what worked for me, after countless attempts at re-installing various HTC drivers, different cables and ports, etc.

Bump. Still looking for answer to this. I have RUU'ed both to Sense and Google Phone editions and the problem still persists, the phone does not detect its connected to a computer and change to mtp accordingly. Only way I was able to get the RUU in there was through fastboot, which is again the only time I can access the phone through usb. Adb is no luck in either android or recovery.

Have you tried revoking the USB debugging authorization and then accepting the RSA fingerprint key again when connecting to PC?
Obviously it can't be an USB cable problem if you can connect to it in bootloader mode and use fastboot commands.

To clarify, the phone just charges when connected, it does not detect that it is connected to PC so debugging doesn't even trigger, neither does mtp. I don't even get the slow charging notification

Does it do the same when you plug it in and reboot the computer to "pick up" during boot up process? Or if you run a live CD? I never had an issue like that with my phone but I did have a similar problem with the USB external blu ray drive I bought some time ago. The pc just didn't detect it at all not on any of the ports until I rebooted my PC with the drive already plugged it and for some reason it picked it up. <Not a solution as I don't know what caused it to not be detected in the first place but still...
Not sure if it's an issue with the device(Phone for you, blu ray drive for me) or if it's a problem with the PC even though other things might still work for you as it definitely did for me(phone, headset, mouse, keyboard, usb extender + all the external hard-drives connected to it)...

Problem exists in all computers, Mac, pc, linux

Did you try what I suggest in Post #6 above?
This worked for me when I had the same issue. adb and fastboot would work, but it would not mount MTP.
And just in the last day or 2 I helped someone else with the same issue and fix.

The phone doesn't show up in device manager.

Have you modify the Kernel? (Applying some settings for example)
I browsed over the web for this issue and found some people with the same problems. They solved by removing the settings applied on the kernel or flashing a new one.

I've flashed various kernels and ruu, still same result

Zenfone 2 not detected when connected to PC

I was trying to transfer some files to my phone through a USB cable today, but the phone was not recognized by the PC at all (Even though it was working a week or so ago). I had some issues before with the cable needing to be still in a certain position or it would disconnect from the PC, so I tried using another USB cable which didn't work either (I tested both USB cables with another device, and both cables were working and the other device was recognized by the PC).
I also updated the USB drivers on my PC with the official drivers on the ASUS support page, and tried putting my phone in fastboot and recovery mode, but both were still not being recognized by my computer. My phone still charges properly, but I am wondering if the USB port got damaged somehow so that it can't connect to a PC anymore?

uninstall and reinstall the drivers. Ensure that phone is not connected during the process.
also have you upgraded your pc os ? if yes then its a little cumbersome to get the same working...
i changed from stock to cm, it is showing well now ... using RR now

Is your phone encrypted? If so you need to unlock in order for your pc to recognize it.

Thank you both of you for the help, unfortunately, my phone was not encrypted so there was no need to unlock in order for it to be detected. Uninstalling and reinstalling the drivers didn't work, and my PC was already on windows 10 since a few months ago. I would also prefer sticking to the stock ROM for this phone for now since they keep coming out with updates.
In addition, I tried using a USB OTG cable to see if the phone could detect the USB drive and my phone couldn't (it has worked before, and my old Galaxy Nexus could still detect it). I also tried plugging my dualshock 3 into the phone, and it also couldn't be detected (also had worked before).
It looks like it's actually a hardware issue and my only option is to RMA it now. I'll have to do it at a time when I don't need my phone as much or when I am not as busy.
PS: In case anyone else has this issue in the future, quick charging also no longer works

zenfone2 I also experienced that, and I have tried several ways, but remains unchanged. I was dizzy today :crying:
