Not sure if it is supposed to be disabled on purpose or not.
Assuming you're a local admin and it's a windows machine, you can enable the USB-controller device by going in the control pannel -> devive manager. Locate the USB controller and if disable, right-click on it, enable.
That's also a good way of "reseting" your device if you encounter errors with it.

Yeah, its windows xp sp3... and required hrdwares are also present in the machine.. but it doesn't show any "usb controller" in device manager list(supposed to be there in last)...I installed the chipset drivers in that pc...successfully... but then too not showing the PD.

There are a handful of ways to disable usb in a computer. Easy way would be to unplug it directly from the inside of a PC. It's also possible to disable it through the pc's bios. And it can also be disabled by disabling the driver like the one mentioned above. Also it could be disabled through registry and group policy if on windows machine. There are alot more ways to do it that I didn't mention.

Thanks Riyal, i'll be trying that through bios and..i'll chck if hardwre is unpuged...
Tell u nxt day..

I would first update the usb drivers. I dont know if its your computer or one in a lab or whatever but if its running XP. Its a good chance the drivers havent been updated in awhile. When you say disabled, do you mean when you plug in a usb stick nothing happens or do you see in device manager that its disabled. Also it would only be relative to the motherboard controller if your using a front access usb port, as a back usb port is built in, have you tried other ports? Lastly there is always the bios, bios is probably hasnt been updated in awhile if this is not your computer, but make sure any usb controllers and or legacy usb devices are enabled.

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

Zune cannot detect device [SOLVED]

I have tried reinstalling Zune, manually selecting drivers from Zune under Update Driver. But no affect.
Something else that I can try to solve this?
Check the USB port & cable first. Try to reboot PC (with power off) and connect handset to the different USB port.

Tried everything.
Have you tried to restart phone?
I had the same problem last night.
Fixed it by plugging in the USB cable to the actual motherboard. In other words, the back of the PC. Not a USB hub, or the front port USB on most computers, since those are not really connected to the motherboard (it is, but with wires/cables).
Worked perfect after that. I did re-install Zune and reboot my PC several times before I tried that.
Well the USB port is working fine, tested with other devices. Tried restarting the device as well as the PC, no affect.
It's kinda strange. Does your phone appears in the device manager? (you should see "Windows Phone USB Devices -> Windows Phone USB") Also, what the WPConnect.exe says?
P.S. Possibly your phone's USB connector is damaged; also, did you tried another USB cable?
It was detecting with a yellow "!" sign but then I added it manually.
What does these things mean or affect in the advanced settings of the device?
Port setting -> USB Switchng ->
QC Composite
MS Composite
Yellow "!" sign means your device isn't function properly, driver not started.
And I have no idea what are you asking about. Could you post a screenshot?
P.S. BTW, something wrong with your phone's USB connection: socket or cable. Did you tried another cable?
Hey, lamborg, did you resolve the issue? The good manners is (if you don't know that) at least inform people who's tried to help you.

This always works for me too. Usually my phone is detected/charges in the PC front ports, but in order for Zune to sync with the phone/Zune HD it must be plugged into directly into the USB ports on the motherboard. I have one of those early USB 3.0 PC chassis' and mobos...and which they usually have to be plugged into a 2.0 port too to sync.
Had the same problem a few days ago, had to uninstall the actual USB hub and reinstall it again on device manager. Actually, I uninstalled all USB ports, but luckily I still have one of those PS/2 mouse to reinstall those ports xD
Well the switching of mode of USB did worked.

anyone figure out usb mount???

anyone figure out how to get usb mount for the s3 for Verizon. Im looking to purchase one within a day or 2 and just wanted to make sure if i hook my phone up to the comp. will it let me copy files over like things used to be?? Don't want to have to set up some type of server and do it that way just want to plug and go.... thanks for any feedback it will make my purchase that much easier......
it comes built in... its not called USB mount, its either MTP or PTP. I haven't really figured out the difference between the two yet, both seem to work just fine for browsing the files on the phone and ext card.
so plug and add files from my comp is a go then... good to hear,,,,

If you have windows plug and go as windows supports mtp natively. If you have a Mac computer there is a file from Google you download and install that gives the macs mtp access.

I find the PTP setting (i.e., appears and works like a USB thumbdrive) more convenient than MTP, which has a specific interface that not all Windows applications are able to handle in my experience. I use MTP for "synch" programs, such as MediaMonkey, which act like a more open and usable form of iTunes for our Android phones.
- ooofest
Someone else posted something similar to this in another thread and I got a bunch of flak for answering that Mtp works the same as mass storage mode. Apparently people running Linux cannot use this option, and it is different than mass storage or usb mode and I don't know why. Still have yet to get an answer in the other thread "how to enable mass storage mode". Maybe I can get one here?
Sent from my SCH-I535 using xda premium
Linux has been shown to have different results depending on using MTP or PTP. Windows doesn't seem to care except sometimes it gets picky and doesn't recognize the "hardware ID" of one version but does of the other.
If connected to a PC via USB and your phone is set to MTP, it's seriously as easy as drag and drop.

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?
Sent from my Nexus 5 using xda app-developers app
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.

pfm
this is what i did to fix mine
first i uninstall all drivers
went to device manager when i had my nexus 5 hooked up and it show nexus 5 with a exclamation mark so i uninstall.but usb debug has to be on.
now disconnect phone and turn usb debugging off .
after u do that connect phone and click on storage and click on 3 dots on corner and select mtp and drivers shoud install and it should work.
its all i did. keep trying.after uninstalling drivers reboot pc 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!

computer does not recognize shield

i'm trying to connect my shield to my computer to do some basic android development (i have an app, it works on other devices, want to test it on the shield).
my problem is, when i plug it into the computer, nothing happens. to clarify, i don't mean that the drivers don't install correctly and then i can't do anything. what is happening is actually nothing. the computer (windows 8) does not recognize anything is happening, the device manager does not see any new devices even after scanning for hardware changes.
the shield is in development mode, and has usb debugging turned on, but i don't get any response anywhere. the shield does at least appear to charge over the usb cable, but that's it. listing adb devices also provides no output.
do you guys have any idea what might be going on that the device isn't recognized on any level that i can tell?
It sounds like either the USB port or the cable you're using is faulty.
Have you tried switching USB ports, to see if it's recognized then? And have you tried using a different cable?

If youre just trying to connect thru adb you need the universal naked driver. If the shield isnt being mounted try a different usb port and make sure youre using the shield cable as well. My samsung cable will charge it but i cant transfer data with it.
Did this get solved?
Did this ever get solved? I have the same issue. I have tried everything everywhere has said to do with no luck.
