[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.

Installed the tmobile samsung galaxy SII USB drivers , I am using windows vista and it does not recognize the phone. I tried another vista computer it still can not recognize it. I tried an XP computer, it still can not recognize the phone.

Still no luck
any suggestions will be appreciated

since you install the drivers into multiple computers and tested them all... it might be your phone.
First can you give more detail on what happens when you plug your phone in? Does your computer make any sounds or searches anything?
ALSO Try installing kies.
if that doesn't work either... looks like you need a warranty exchange

Try using an oem Samsung usb to micro usb cable. I had this problem with my Samsung Galaxy Epic a while back. Everytime I used a generic cable lying around my computer would not recognize my phone. When I used a Samsung cable it worked. Your computer should automatically identify your phone using the right cable. If not re-install them and don't forget to restart your computer before attempting to connect to your computer again. Good luck.

I've had this problem too.
Initially I had kies installed and had to launch the program to access the two 'mounted' removable drives.
I assume the drives mount, but you can't access the drives?
If that's the case, look on the phone and pull down the status bar and check to see if it sees the USB connection. Select that, and allow it to connect as USB storage.

thanks guys for all the quick response.
The problem seem to fix itself. After removing and attaching the USB cable a number of times, the PC suddenly recognized the phone.
I don't know what fixed it.
Now, I can proceed to root my phone!

you probably didn't give it enough time for the pc to actually install the needed components.. it takes a good 5-10 mins for everything to finish installing

I'm faced with the same problem. Only different is, as soon as it shows connect to usb from the notification bar if goes away. I tried the usb tool in wireless but still wont work. I tried the samsung cable as well

know it sounds dumb, but have you rebooted lately? mine wouldnt recognize the sd card when plugged into comp....rebooted....all is well

Is there any way to root or update without usb

My s2 is on gingerbread stock and apparently my usb port is broken as it only charges the device when connected to the computer. Is there any way to update to ice cream sandwich or root without usb support? Cant I just put root files in the sd card?

There is no way, because you have to Odin flash CWM in order to flash SU to root your phone. Are you sure your USB is broken? Have you tried downloading the drivers for the S2? Have you tried rebooting your PC? Does your phone show the USB symbol, and ask if you want to enable USB storage?

Thank you for the response, and yes im almost positive its broken, I have tried 3 different pc and 5 different cables when I connect to a computer it just charges the phone. No notification of usb no nothing, have tried factory reset plenty if times. Even if I didn't have drivers it should still show that it is connected to pc via device manager but nothing. My friend has an s2 as well and his plugs right up on the computer and immediately gets usb mass storage notification.

When you connect your phone to a new PC, or even a different USB port, does a USB mass storage or finding driver dialog box come up? Is there anything you can eject under safely remove hardware....ect on the taksbar? Anything under system properties / devices that show up unknown or say Android or ADB on it?

Nope nothing, its doesn't even show up on the device manager the computer doesn't even react to the connection, it just starts charging. I have read that this is a common issue with the s2 and the usb port needs to be replaced. Its about $7 so im not to worried about it.

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?

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

[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'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?
