Can't access USB mass storage on my PC - General Questions and Answers

So I can't connect my Droid RAZR to my windows 7 machine...
I have tried a lot of things!
I've tried:
*Different computers including Vista and Linux
*Different cables
*Different fastboot files
*Re-installing drivers
*Factory reset
*PIM sync from the market etc.
What happens when I plug my phone into my PC is the computer recognizes it, it makes a sound, then it says Unknown Device connected or some times it says USB malfunctioned and then on my lockscreen it says the phone is charging but it doesn't show on my battery icon.
Whats also interesting is if I got into Fastboot mode and connect to my computer it says USB connected and then I can use it in RSD with no problems.
I'm on ICS with no root.
Please help!

Try turning on USB Debugging (if you haven't), under Settings > Applications > Development.

I had the same prob with my S3... Tip from Post above solved my problem...

With the phone plugged in, have you tried opening up the lockscreen so you can get to your phone? Please take a screenshot of the device manager settings.
Computer Management -> Device Manager -> Find the device (double click on it) -> Details -> Hardware Ids
Or you can write out what the hardware ID is. Thanks.
YOu said you also tried it in linux. please post the output from lsusb for any unknown devices

I am also having a similar issue with the pc not recognizing the phone. I never had an issue with this problem. I have only rooted my phone with no custom room. I have always connected my phone to the pc and was giving a connection screen on my phone asking me if i want to connect as a mass media storage. A week ago this behavior stopped. I don't know what to do anymore. I don't remember doing anything to the phone to mess up the setting? I connected it to several computers using different micro usb data cables and nothing occurs.
The only thing happens is my phone receives a charge from the computer and thats it. Any ideas? Is there anyway i can reset the system or what not?

me also facing same problem and already i turned on USB Debugging mode but nothing happened. still i can't connect USB mass storage of my android device

Hey guys what you should try to do is use this :
after pluggin in your devices and removing their current driver in device manager(control panel>admin tools>computer management>device manager>
and then install this
http://adbdriver.com/upload/AdbDriverInstaller.exe
also make sure you adb debugging is enabled (if it's not visible(setttings>about/info>build number tap it multiple times) usually its settings>dev options>usb debugging.
also maybe try using this software as pc suite myphonexplorer

Can you guys go to the storage menu in settings, press the menu key, select USB connection mode (or something like that) and play around with the settings in there? Try that out.

[Q] drivers disappear?

after i rooted my phone, i pluged in my device into the computer and click mass storage. but it dosent show up on my computer. i havent changed anything on my computer so it could be something on the phone? would usb debugging make a difference cause i have that turned off?
is it the drivers are no longer on my computer?

first thing, try rebooting your phone and computer. also make sure that your memory card is mounted (settings>sd and phone storage). secondly, are you SURE that the computer isnt recognizing it as a drive? Co to My Computer so you can see a list of available drives and see if its in there. Sometimes you wont get the popup on your screen.
Drivers normally wont just disappear unless there was some type of system error. You can also go into device manager and make sure that it shows up when the phone is plugged in. If that doesnt fix it to avoid a long drawn out troubleshooting thread, try picking a day before you rooted and go to system restore and select a recent restore point. If you do that and it still doesnt correct the problem, then it may be time to troubleshoot the phone
and USB debugging wont stop your computer mounting your phone as a drive. When you pull down the notifications panel once plugged in, you should still see the option to use a USB drive whether USB debugging is enabled or not
Thanks man yea I figured it out the system fixed the drivers so it connected

Captivate will not connect to computer

I'm trying to unlock my dads old Captivate, but I need to connect it to the computer to do this. No matter what I do, this phone will not connect or be recognized by the computer. I plug it into the computer and it makes the little beep it makes when you connect, but thats it. No "USB Connected" on the top bar or anything.
I can connect my captivate fine, its just his. I've tried uninstalling and reinstalling drivers and that wont work. Any ideas?
Do you have the drivers installed?
Sent from my SGH-I897
Ye, the drivers are installed. Would it be a driver problem though if my one captivate works, but the other? That sounds like a phone problem to me.
Settings> applications>usb(something or other)> mass storage.
Also make sure usb debugging is enabled...
The froyo settings might be different...the usb options could be in "wireless and network" instead of applications.

Nope, that doesnt work either. Its like its not even connected. Nothing showing up on my computer, nothing on the phone. The only thing that shows up when you plug it in is the charger icon comes on to let you know its charging.
i would recommend that you try another computer if that doesn't work, restore your phone to factory and if that doesn't work then you have two out of three possibilities that might lol, be seriously i think its not a drivers issue if the other phone is working. It might be a problem with the computer recognizing the port i really cant think of anything else..

If it's not connecting to either captivate it's a driver issue. Make sure that USB debugging is on and that under the application usb setting you have it set to ask on connect. Try a different usb port on the pc, or another cable. I had a bad cable a while back that would charge but not connect, it was even the one that came with the phone.
Use a USB port off the back of the computer, coming DIRECTLY off the MB. There have been tons of issues with using remote USB ports. If it's beeping when it connects, it's being seen by the computer. Just that there's a problem with getting the proper info.
I get this problem sometimes too. This is how I solve it. Under USB settings select Samsung Kies and plug the USB cable into your computer and phone. See if your computer recognizes your phone. Mine won't recognize Mass Storage but will Kies. I don't have the program installed so windows will say Drivers Not Successfully Installed. Once you have done that, restart the computer and phone with USB cord unplugged. Once both come back on, switch your phone back to Mass Storage and plug in your USB cable to both the computer and phone and see if it will be detected by your computer. If not I would try a different USB cable. That is what works for me when I have that problem.

Some cappies have issues with generic cables. Make its the original or a high quality one.

Would be a good idea to check if the following
1. Settings- applications- USB settings : make it ask on connection.
2. Change the USB port which you connect

Nexus 5 Is not seen on PC!

For some reason, my N5 can't be seen on my PC. It doesn't show up in device manager, and the phone itself doesn't prompt me for any kind of connection (mtp for example). I think its a driver issue, does anyone know a way to help?

Same thing with me. But I screwed something up.. I was having trouble with the drivers so I used the first guide on theandroidsoul that was posted in the stickied how to unlock the bootloader thread. After I uninstalled the driver in device manager on my win7 computer like it says in step 3 of the guide my computer no longer detects my nexus5 or nexus4. They both charge but they aren't listen in device manager/no connection sound when I plug them in.
I have restarted my computer a few times. Made sure usb debugging was on in the developer options.Toggled MTP on and off. I also checked on another computer that it wasn't the usb cable.
Same here! anyway to get those old drivers back?

Okay now this is weird. Anyone reading this must think I'm and idiot. I know for sure it wasn't working before. I used 3 different usb cables on both n4 and 5. I wiggled them and held them in place leaning in different directions just in-case the usb male end wasn't making the connection. I just tried the n4 one more time and it worked, then tried the n5 and that worked too.

I tried this a couple of times! PTP but MTP isnt...
If anyone was playing around with NRT or other similar tool kits & had universal USB drivers installed to unlock, install custom recoveries & root, that could've "wrecked" other drivers & settings on it (Windows 7 ??) - one way to restore the connectivity to the N5 is to use MS's System Restore, go back to the earlier date - it should be successful restoration after it finished & reboot. Strange & hard to explain, but it worked & it was too late at night for me while helping out to work the logics behind it. The laptop normally see the N5 upon usb cable plugging in & open with the prompt to read the folders & files.
No matter what, usb debugging off & on, it was no good - only recognize the N5 when switched to Camera (PTP) mode & can only see 2 folders, normally - MTP or Media Device is the default setting & all the "SD" folders visible ...
Once reconnecting via usb cable, let it sit for 1 or 2 minutes so that the drivers can "wake" up and install & recognize the device(s).
Grrrrr, upon further checking with my old faithful HTC, the desktop OS seemed to have "corrupted" the USB drivers and now it is only reading it as a Removable Drive & not as HTC device.
I would go back & follow Littlegreenalien's steps to see what happen and then attempt a System Restore, time to brew up some coffee this weekend & deal with this minor challenge. Wondering if it's the new KitKat thing - and, sidenote, both N7 (2012) and N5 are generating random bug reports even on rooted stock rom & kernel. :cyclops:
Didn't think of a system restore! Man that's a good idea, I'll try it when I get home. My N5 also generated a bug report around when I was trying to fix this problem!

This was the answer for me as well. All android drivers need to be uninstalled, then let the computer detect the N5 and install drivers

Let us know how it turned out, look at Window's Control Panel, do you see Portable Devices & under it, it should say Nexus 5, and click it to see the drivers (total of *.dll's and *.sys on my W7 Ultimate 32-bits OS)
Now that everything has been restored, "Auto Play" popped up after a pause of few seconds with usb making connections. Rebooted the laptop & now it's seeing the HTC again after auto reinstall drivers.
Just in case anyone, off-topic slightly, if anyone is playing with their Nexus 7 sideloading KitKat & small OTA patch, you should also see Android Device under the Control Panel & the Google Nexus 7 ADB Interface - with USB Debug enabled. But, with the Nexus 5 connected, it is showing "Google Nexus 4 ADB Interface" while showing it as N5 under Portable Devices ... what the heck !
I'm going to leave it alone for the time being, if it ain't broke & is working, leave it alone & let it be. Call me lazy, TGIF - not going to go thru the routines of uninstalling drivers, rebooting & all that and ruin the webcam, camera & other usb drivers loaded on the laptop. I can run ADB and Fastboot commands, etc. just fine now.
The simplest and shortest way to connect google nexus5 with PC as MTP(Media device)

When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).
What you have to do is:
Unplug the device from the computer
Go to Settings -> Storage.
In the ActionBar, click the option menu and choose "USB computer connection".
Then select Media device(MTP) or Camera(PTP) based on your requirement...
Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection..
I hope this will help!

[Q] Nexus 5 not connecting to computer (usb), does not show in device manager

Hi,
I would like to see if I can get anyones assistance with solving my problem. I have lost the ability to connect my Nexus 5 to my computer via USB. I had previously been able to connect the phone without any problems.
Connecting my phone to PC charges the phone but no drivers are loaded, nothing changes in device manager and I cannot see a change in windows explorer to view the memory card.
So far I have tried the following:
searches on various sites
rebooting phone, starting in safe mode, wiping all data, performing a hard reset
connecting other phones to usb cable to check that it is not a charge only cable, also trying several other USB cables
connecting phone to other computers
connecting other phones (HTC) to load drivers (then uninstalling drivers)
displaying all hidden devices in device manager and removing all drivers that resemble something to do with mobile phones
uninstalling programs I no longer require on the PC
using "wugs nexus root toolkit" to uninstall and re-install drivers
checking & unchecking MTP, PTP, developer options, USB debugging in various combinations to elicit a response from the computer.
I have also tried to visually check the connections of the USB port on the phone wondering is there is a break but I cannot see very well.
does anyone have any further suggestions to get this phone connected to a PC?
my only last thought is to attempt to open the phone and check the resistance of the plug connections.
Have you tried enabling and disabling usb debugging while plugged in?

Are you sure you're using a data usb cable and the usb port is good?
Same Issue
same thing happened to me today when i connected the device to PC.
Mine says unknown device on PC under other devices. so i hope my USB port is ok.but im not using the original SUB cable. i wonder that's is the issue. but it didn't bother me until today. my original cable is at my friend's house.
Tried updating drivers manually. But following error message occurs once i select the drivers folder and hit ok.
Windows was unable to install your unknown device
Please help.
so, not really a solution but while at work my phone fell on to a nice rock cracking the screen. I have replaced the phone and the new phone connects to the pc fine, drivers come up without a problem (I will put this down to a fault with the phone)
Thank you for your assistance

USB Problems

My computer for some reason reminded itself of not recognizing my Idol 3 5'5 6045k. Two days ago it was all fine and now everytime i connect it to the computer it only charges. I've tried everything from changing usb cables to unistalling andthen installing the device drivers, enabling debugging, restaring either smartphone and computer. Everything I can think of. Please help me out, I'm trying to root the smartphone and without it recognizing I can't do anything, not even transfer files. :crying:

Obvious Question #1: Did you check the phone notification dropdown area to verify the phone is in MTP or PTP mode so it will show up on the pc? As for transfering files...you do have the option of loading up a microsd card with whatever files or installing a wifi adb app to connect wirelessly. You could even use an app like airdroid to let you do all sorts of things.

Therre's no notification after connecting the usb, it just charges the phone, seriously, I've tried everything to enable MTP but nothing does the job. And what do you mean by using an adb app? Can I root my smartphone by a wireless connection?

You are overcomplicating things. 1st...there is ALWAYS a notification in the dropdown that says what mode the phone is in....mtp, ptp, charge only or "cdrom mode" which installs the usb drivers. Pressing on that notification allows you to change the mode the device is in.
As for rooting....all you need to do that is to flash or boot TWRP (details on booting it are in the system image thread) and then flash the supersu zip from inside twrp to your device...reboot and done...but I think in the newer TWRP's they even offer options to root automatically...ie the zip is already built in. After rebooting to your phone you install the supersu apk from google play so you can configure what apps have superuser access.

Your telling me when the phone is plugged into the pc you don't see the notifications below or some version of them at all? If so then you need to fully uninstall the devices in device manager including remove the drivers...then use the drivers in the system image thread (since you obviously can't use the ones from "cd rom mode" which would be the best solution). USB debugging isn't even an issue yet...your phone should still show up to the pc as a camera device (ptp) under just about ANY scenario using even built in windows drivers.

Have you tried a different cable? Perhaps that one is damaged or is only setup for charging? Only thing I can think of.
And then I realize you mentioned that Not sure what else would prevent it from giving you those options.
I'm also facing similar issue after the 2 update. Were you able to fix this?

Which kind of USB cable(s) have you tried specifically? Were they cheap eBay/generic kinds or well known branded ones?
Something as little as a Micro USB cable can cure a lot of problems. It needs to be a well built one by a known manufacturer to avoid problems.

Actually I've been having pretty good luck with the $1 ones from Dollar Tree but the key is certainly to try multiple cables....on some the microusb plug will make it difficult to get a solid connection especially if you have a case on the phone.
You may be missing the point of "trying" different cables. It's not so much the "quality" of the cable, it's the fact that some cables are for "power only", and "will not" transfer data, regardless of how hard you try.
You need to be using a "proven" data/power cable, otherwise your beating your head against the table for nothing.
Just to add, I put a piece of red tape on all my usb cables that are power only, no guess work.

I had the same problem as well. It only showed charging when I plugged in the USB cable. Tried switching cables, turning off and on USB debugging but nothing worked. I finally just rebooted the phone and then it worked again. Strange that it suddenly stopped.
I have a different issue; the different USB modes work fine but I don't have the 'cdrom' option in the USB mode dialog. I've tried various Alcatel ADB drivers that I have found and none are working, using Win7 64. My Idol 3 4.7 is 6039I (US).
Answered my own question, simply install the Mobile Upgrade Q software.
nope, doesn't show up. it's a bug. i had it before, googled until i found a fix and got it working, now it's back to not being recognized. nothing shows on drop down menu.
