I have tried just about everything to get my Xoom to work with my 64bit Windows 7 system, but the various steps do not work. What is even more odd is that I have a laptop with windows 7 64bit enterprise that works perfectly with the Xoom.
So here are the symptoms:
1) When I connect the Xoom without debugging on, it tries to install a driver, but fails with a message about MTP drive failure.
2) When I turn debugging on, it installs a driver and tells me that the Xoom installed, but then my computer goes wonky. I can't open "My Computer", it like Windows Explorer freezes up. As soon as I disconnect the Xoom, my desktop works correctly again and I can go into "My Computer".
A few times i've gotten into "My Computer" after the Xoom installed, but when I double click on the Xoom icon it just times out.
The only difference I can think of between this PC and my laptop is that in the past I've connected my Droid X to this PC, and used those drivers. I'm not sure if it is some sort of issue because of the X or what. I've installed, uninstalled, cleaned, restarted, etc... with the Motorola drivers.
Its driving me nuts. Has nobody else had this problem?
Did you try different USB ports on your computer? I was kind of experiencing the same thing. I'm also running Windows 7 Enterprise x64. My explorer window would freeze up when I tried to transfer data from my PC to the Xoom. While frozen, switching from/to normal/debugging mode would unfreeze things, until I tried copying again.
My problem was resolved when I connected my Xoom to another USB port on my PC, one that was integrated with the motherboard. Previously, I was plugging it into one of the front USB ports.
So my suggestion is to try a different USB port, preferably one that's on the back of your PC.
i ran into the same issue as well.
this was fixed by changing to a different usb cable, and inserting it into a different port.
if you're connecting it to the front of your computer USB connector, try connecting via back of your desktop computer.
this worked for me.
Like another poster has suggested, the usb ports on the front of the base unit or ports on a usb hub might not be powerful enough to run the Xoom. I've had the same thing with external hard drives.

I've successfully connected my xoom to 3 Win x64 Enterprise boxes.
If I had to guess, I'd say that your front USB ports are either failing or under powered. I assume that you've tried a USB port on the back?

Hello.
Three weeks ago my Nexus 4 is recognized by my three computers (work, home and friend) like a drive. Now it is not anymore recognized by friend 's computer: I hear the sound of connection but no change in file manager. However it works fine on two other computers (home and work). In addition the Nexus 4 of my friend is always recognized by these three computers.
I tried to install N4 drivers on Friend 's computer. No change, my Nexus 4 is not recognized by friend's computer. I tried the debug mode too. No change. And the nexus 4 of my friend works on the three comptuters. Very frustrating .
These two Nexus 4 is updated with 4.2.2, in stock rom, not rooted, 16Go, v11.
Does someone could help me to solve this problem without saving my data and then restoring to factory values?:highfive:
Thanks.
I forgot to write that i used only one usb wire on the same usb port. To be sure that the problem is not the wire or the usb plug.
Do you currently have USB Debugging turned on? Turn it off and see what happens...the reason I say is that my work PC can either see is as MTP with USB Debugging off or through adb with it on - not both.
My Windows 8 Pro laptop at home works fine for both at the same time...worth checking out
Maybe try to uninstall the driver using the device manager?

Thanks i will try your solutions tomorrow. But these solutions doesn't explain why one Nexus 4 works on the friend 's computer and the other Nexus 4 doesn t work: same wire and same usb plug.
I plugged the nexus on my computer. And I unistalled the driver of nexus in my device manager unplugged and plugged again the nexus. And then let windows recognize the nexus and install his own compatible driver. Thanks nhatters.
The problem was that for run application named carbon I had to install in computer first the adb driver and carbon for computer. And this driver does not recognize my nexus which have not carbon (for mobile install).
i had the same problem few minutes ago .. i just turned USB Debugging on and voila the PC detected my nexus 4.
Aha i had the same problem i just lowered the notification shade selected usb device n selected camera option and reverted back to the media transfer and that fixed it
I am having the same issue but nothing seems to work and I dont even hear the connection sound in windows. I've tried uninstalling and installing drivers with sdk, device manager, and the other thing in windows which is callew dew I think and nothing no success, also I have tried to disable usb sebugging and mtf media storage and nothing. Is the only thing left to is buy a new micro usb cable?

Same problem for me on Windows 7. I have tried everything - different cables, different ports, enable/disable USB debugging. Even uninstalled drivers etc. It is getting detected on Windblows and is showing up in the taskbar as an USB device with a green mark. But it is not showing up as a drive or the MTP device. Frustrating to no end!
im gonna try to research in microsoft website which drivers are not originally installed in my computer and delete all the wird ones maybe some other driver from another hardeare like another cell phone or something is interfering. Hope I dont delete something that will make my computer not work right.
Same here, I can no longer transfer any files on to my Nexus 4 anymore. I'm using a PC and it no longer reads it. Only fast boot and adb on recovery works.

It's not the same because I've tried adb and nothing. Your problem can be fixed by modifying google drivers. In the other hand I tried a friends nokia phone with same usb cable and started installing drivers right away.. Mine does nothing, not even a connection sound just charging. so It's not the cable. I'm starting to think the micro usb port got damaged or something really wrong with the rom but still I've tried to see if reseting the phone works and nothing.
Seems like its an issue with 4.2.2. Since last week my N4 was acting very strange. when I connect to my pc; It would connect and disconnect every second. After checking in Device Manager; my Nexus 4 was listed under SAMSUNG Android Phone . I end up uninstalling it (plus check delete driver software). Then I rebooted my computer. It reinstalled the driver and now its working. Thought my wire was broke.
This worked for me, it shall work for everyone else
Open the start menu and type in device manager and click on it, it should npbringba window up. Now at the stop it should say android device or something similar, drop down that section and right click to delete "Google ADB Interface" which was for me should be for you also. After make sure you check the box in the confirmation to delete the driver. Reboot your PC plug in your device and enjoy!!!
I can't connect my phone to laptop it always shows it as unknown device .I have uninstalled it couple of in device manager and plugged it still same even its in USB debugging enabled .keep rebooting my laptop and keep trying still the same

If you have an unlocked bootloader use this tool to lock it: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker
To unroot use the permanent unroot feature in SuperSU.
Order is important since the Bootloader tool requires root.

thanks. i installed the android sdk and java jdk but still have the problem. i believe the problem is with the phone 100%
my nexus always shows that it's charging on AC whenever plugged in. doesn't matter if it even is to AC or USB. the phone shows up as unrecognized device with a bang in the USB section of the device manager. on some computers it doesn't even show up.
i tried on my macbook pro and it doesn't even show up there but in every case, the phone charges.
wondering if there's a switch or toggle somewhere that will turn it on and get it working
i'm going to install a windows xp VM as a last ditch resort and see if it at least shows up there.

Make sure your device is on MTP and try an other data cable which has no missing/broken data wires inside.

yep it tried on mtp and ptp with 4 different cables. two original nexus 4 cables, one nexus 7 cable and a blackberry cable. they all work with my other nexus 4... just not this one.
the windows VM didn't work unfortunately.

That is strange, it should work with the Windows Virtual Machine.
Maybe it is to do with the standalone machine using it in the same time.

Same problem here. USB is not recognized using my Nexus 4 ( it used to be recognized on two PCs, but no longer), but another Nexus 4 connects perfectly. I can only charge a USB rate on chargers that used to charge at ac rate. I've tried everything, and more than mentioned in this thread.

Hi guys,
Seems that I've got the same trouble. Got my N4 (stock ROM, 4.2.2) a couple of weeks ago and everything was ok - connection as MTP, connection for debug and so on. But yesterday I connected it to my PC and found that the device indicates charging but not USB connexion. So I've tried to reboot PC and N4, tried other cables and 2 other PCs (my with Win8, and those with Win7 and Linux Mint if matters). Other devices are ok (Huawei Honor, N7, Milestone2).
The phone just doesn't detect USB connection - in both MTP and PTP. Then I tried to plug in wall charger and connect back again to USB. AND IT WORKED! The phone detected the connection so I was able to mount it and detect with adb. I thought that the problem was solved but when I connected it next time - same ****. This time nothing helps (most likely that there wasn't any casual relationship between wall charger connection and temporary fix...)
What options I've got now? Try to root the device and look into syslog to detect if it's a software issue or disassemble the device and try to find any defects on USB port?
Thank you,
Alex

I got mine to work by using a 2 into 1 usb plug. The kind that comes with portable CD writers. Once I got it working I reflashed stock 422 and the problem is gone. Turns out it was a bad flash from the previous owner.

Thanks for advice. During this day it worked properly twice - the phone just started detecting connection. No obvious reasons for that... I got a new device with stock 422 from amazon and haven't flashed or event rooted it. How do you think, should I try to flash it with official 4.2.2? Now I can say that it's most likely a software issue.

Tried it out - the result is the same. Now I can not even unlock the bootloader to reflash 422... Btw I didn't managed to find a 2into1 cable but checked if the same trick would work with USB hub with external power - it works really better. The device can detect the connection almost all the times and I can see it listed in adb devices and as a mounted storage. Though in fastboot mode this doesn't help. Device remains unrecognized.

well if you're getting a connection to the computer but not in fastboot, your drivers might just need removal/reinstallation.
once you get it going, reflash the stock 4.2.2 from google and see how it goes.
if that doesn't work and you can get it going, get it replaced by Google.
if you can, try it on a mac.. they don't need the drivers installed. just run it all from terminal.
Okay, I've managed to track down the issue...
Once I got it available for fastboot I've unlocked bootloader and then flashed with Cyanogen. The problem remained but I could get dmesg output for plug-in event. I've managed to get logs for problematic case (doesn't detect USB data connexion) and for correct behavior case (when Android detects USB data connection).
No sense to put the whole log pieces here just a brief quotes.
For correct case:
Code:
Avail curr from USB = 500
For incorrect case:
Code:
Avail curr from USB = 1500
USB module firmware tells the system that it has detected data-connection and enabled low-power mode (500mA). In this case Android initiates mtp and adb:
Code:
<6>[62539.001178] adb_open
<6>[62539.001269] mtp_bind_config
<6>[62539.001422] adb_bind_config
And in problematic case USB module firmware incorrectly indicates for the OS that there are only power-connection (5V/ground). I cant say exactly where the issue is but there are only two options - bug in USB module firmware or physical fault of connection (pins, bus or whatever else). Anyway I've to replace USB module or just go with it and use adb over network (the matter is that sending the device back to Amazon seller from my country would cost me 1/3 of the purchase total so I consider that just unreasonable).
Thanks to LG - for my money I got not only a box with device but also whole lotta fun =)
Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?
No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.
I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.
My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

I've been trying all kinds of different combinations of USB leads, phone settings and ports all morning and was just about getting ready to start a new Olympic sport of S4 hurling when I came across this post and plugged my USB straight into the back of my machine and it finally works!! Thank you dirrtpoor for your input - a simple fix, but nevertheless it worked.:good:
I suppose it makes sense that a quad core 1.9Ghz phone would be a power hog.
It wouldn't work on my home PC whatever I tried. Front or back USB ports.
On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.
I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!
Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.

I've tried this on a hub and a USB port on the PC itself. The phone doesn't even recognize being plugged in on a USB port.
On the PC itself though, it connects and I can browse the files within for a few seconds and my phone then disconnects itself and connects back right after. And everytime it connects, there's a vibration so it's pretty much non stop vibrations. This is extremely annoying. I can't transfer any files over. Currently using Wireless Storage. Cr*p speeds but at least it gets transferred. Any idea what might be the problem? On a D802, rooted and with TWRP installed.
Mine will do this when charging in the car via USB. If playing anything out gets paused. Sux

Bump.
Huh i thought i was the only one. My G2 does this too. My PC is pretty old and it was on Win 7 and MTP didn't work. So i formatted my 4yo Win 7 to Win 8.1 and now MTP works. It's definitely much faster than Wireless Storage/OSP/3rd party app but what's the point if it keeps disconnecting.
Another thing is, it does happen to my thumbdrive as well. Just that with the G2 it's much worse until i can't transfer any files at all. So the super slow wireless is the only option.
Any solution? Or do i need to upgrade my PC lol.
Try changing the port. Maybe the usb cord is loose or the port itself. This happened to my S2 after dropping it. Maybe the motherboard was moved inside i dunno and after that it keeps connecting and disconnecting when i plug it,
I think you all suffer from too less power throughput from charger/cable/port.
It's like the same when you do not use the supplied charger but another brand your phone will not fast charge.
I was thinking the same too because it doesn't happen when i plugged the phone on another PC.
So the solution is, unplug unnecessary devices and it shouldn't disconnect anymore. If it still happens, try not doing anything on the pc while data is transferring. At least it works for me.
I am also rooted and the problem only seems to happen when the screen turns off and then locks. If I unlock, it comes back.
same problem
I've used my I9300 on stok ROM, no problem, i've flashed ArchiDroid V2.3.4, and the problems apeard. conecting the phone to pc via usb, it connect's and deconnect's, i'm not able to copy anything to/from phone. I guessed it was a problem with the ROM, so i've flashed Resurrection Remix® 4.4.2 KitKat , but the same problem....don't know what's the problem...a little help pleeeeeaseee
PS: changed the usb cable(cord), the usb port, uninstall the drivers and reinstall them...
(off topic...who copied who on ROM...archidroid<->kitkat)
C'mon....i like archidroid...but i need the usb connection 2 PC, i can't live without it
Problem fixed.
I had exactly the same problem as this, I tried different USB slots (even USB 3.0), I tried resetting the phone several times but still it didn't work.
But after changing the charger back to my original iPhone one, it worked perfectly! Probably isn't that wise buying cheap chargers online tbh http://forum.xda-developers.com/images/smilies/tongue.gif
