Help! My computer won't recognize my phone

I'm running windows 7 x64, and Cyanogen's 3.9.7 and suddenly my computer stopped recognizing my phone, it didn't replace the driver with something else, when I plug my phone in it doesn't even communicate with the computer. There is no drop down to mount, and the computer doesn't even see it as being a connected device, I've tried USBDeview and it doesn't show up as being connected at all. I have no idea what to do. Help would be great.

Does it appear in Device Manager?

Nope, not at all.

Tried it with more then one usb cable? One of my cables went bad not too long ago... Also could try different usb port. If all else fails.. try it on the different computer just to rule out hardware issues. If it does not register on different PC then you may need to exchange you device...
Good luck

DIE XPERIA! DIE VISTA! arrrrrrhhhhh!

Hey guys I realy could do with some help here
When I connect my bran new x1 to my laptop (vista 32)
I get this message....
"One of the devices attached to this computer has malfunctioned and windows dose not recognize it for assistance in solving this problem click this message."
And then i get...
"This device has malfunctioned try reconnecting the device or replace it"
I sometimes had this problem on my last x1 but it worked after few reconnection's (my other usb devices allways work fine and so did my first 2 x1s). After trying over 40 times with different ports and different usb
Cables I assumed that it must be a problem with my laptop.
so I did a full destructive restore totally wiped everything off my laptop. Turned it back on and got a different message when I connected the phone.
"Windows mobile adapter has failed"
I typed this into google looking for a solution and found a few random forums that showed other people had had the same problem in Aug 14, 2008, March 17, 2008. a problem thats over a year old will have been fixed I thought. So ill have to wait for windows update to finnish.
After 16 hours of vista updating and resetting updating and resetting i plugged the x1 in and got this message
"usb devise not recognized. One of the devices attached to this computer has malfunctioned and windows dose not recognize it for assistance in solving this problem click this message."
And then i get...
"This device has malfunctioned try reconnecting the device or replace it"
iv updated all my drivers. iv tried Microsoft's fix it tool that scans your computer for errors and it came back with....
"No problems have been detected on your system."
Iv been on the tech guys website.
Iv tried different usb cables,
Istalling windows mobile device center makes no difference,
Iv even tried it on a different computer (running xp)
and still no joy! xp fails to find settings and asks for the cd that came with the device (I didnt get one with this phone (x1)so I used the one from the old phone(x1i) this didnt work and it also gave the option of searching for settings on the internet, this didnt work ither!
Surely theres something iv missed I cant have had 4 Sony Ericsson x1s and they've all been ****ed? each have had different problems. iv tried phoning Sony Ericsson support all they say is send it off for repair but how many times do I have to send these things off? its beyond a joke! I just want one that works!
Any help with my usb problem would be highly appreciated.
Is anybody els having the same problems?
AAAAAAHHHHHHHHHHH

It could be a problem with the software on my phone coz my insurence companie sent me this letter.....

Generic roms don't need to be HardSPL'd to flash via Micro SD method.
Download one of the generic roms and extract the nbh file (if it's an .exe use winrar to extract the file), rename kovsimg.nbh, whack it on the micro sd card and put the phone into boot loader mode (hold vol down and power when turning on).
Once you have flashed the generic rom, check to see if the usb connection works properly on this version before making any changes.
You should try and get your phone back to stock before sending it away for warranty repair.

You are using Vista, what did you expect lol?

i gave up trying to sync with vista on my laptop. i use xp and active sync.

wish you good luck bro
quite shocked when saw a screen break xperia, lol

I had a Motorola MPx220 which had this problem (I was using XP at the time), the socket on the phone motherboard had gone bad.
If XP is asking for drivers, you need to install ActiveSync first. If you've had 4 X1s and they haven't worked on your Vista computer it is probably your computer. Go back to the XP computer, install ActiveSync (download it off microsoft.com) and try again!
Vista does work with the X1. I think I'm not the only person who can testify to this. It is possible that your computer is not supplying enough power through the USB port- in this case you need to disable charging over a computer USB port on your phone.

have you tried other usb ports? i've had no problems. even on vista 64 or win7 64. i did had problems once, my pc didn't recognize my xperia, but it was to a faulty usb cable, maybe that's your problem too.

Check the settings on your phone. Settings, USB to PC, uncheck that checkbox under ActiveSync. Oh, and switch to Windows 7, bro.

Every now and then (say once every 3 months) I get over-zealous with adding USB ports to my laptop. It comes with two ports standard but I have another two through the use of a PCMCIA extension slot. Say I have a 2.5 HDD, 3.5 HDD, printer and wireless router connected at the same time, most of the ports go bonko.
Thats the source of the "One of the USB Devices has Malfunctioned" warnings. I think its just collectively, there is not enough power to run them efficiently at the same time. Changing USB ports or disconnecting some of the devices tend to work for me.

Pretty sure it's a problem with WMDC caused by a windows update.
You have to delete the device, uninstall WMDC (fully) and reinstall. I'll see if I can find the instructions again.
EDIT:
Uninstall WMDC and WMDC driver update and reinstall the latest WMDC.
OR
Try:
1. Keep your device connected
2. Press START+r and enter "devmgmt.msc" (without the quotation marks).
3. Look under the "Network adapters" node for "Microsoft Windows Mobile Remote Adapter". If this is not present, skip to step 4. Otherwise, right-click "Microsoft Windows Mobile Remote Adapter" and choose to "Uninstall"
4. Look under the "Mobile Devices" node for "Microsoft USB Sync". If this is not present, skip to step 5. Otherwise, right-click "Microsoft USB Sync" and choose to "Uninstall"
5. Disconnect and reconnect your device. Your device driver will re-install and Windows Mobile Device Center will launch.
Then:
6. restart your PC
7. uninstalling (make sure you click the box to remove associated software) both WMDC and WMDC driver update
7. install the latest WMDC 6.1 from link above.
8. restart your PC

ADB device offline

I've been using ADB the last couple of days to install apps on my Captivate and all of the sudden it stopped working today.
When I type 'adb devices' the phone comes up right away, but it shows offline.
I have tried reinstalling the drivers and Android SDK, but no luck. I've searched around and found some others with this issue, but haven't really found a fix that works for me.
Any idea why ADB would just stop working like that? I even performed a factory reset of the phone and put everything back to defaults.

Ok I almost pulled my hair out, but I found the problem.
For some reason, ADB does not work with the Samsung USB cable that came with the Captivate.
I switched to another USB cable and it works just fine.
Man, I really thought I was going crazy.

What the hell is that about!? I wish all these companies would stop trying to break from standards by proprietizing common cables.

I can't get the drivers to work. Where did you get yours?

Yeah I buy that, I couldn't even get the thing to try and connect at all with out switching usb connections on my computer.

stock cable works. I just rooted and ran into that problem. In order to get around it if you cant get a diff cable, make sure that b4 you connect your phone to your pc you turn off your internet so it doesnt auto dl the drivers. b4 u connect, dl the drivers for your phone from the root thread. Plug your phone into ur comp with the internet off and close any pop ups. Go to device manager look for the notification labled usb or captivateand right click and select update. Select search from file on disk or select file (something like that, i forget) and scroll and select the folder where you extracted the usb drivers. Make sure the checkbox that says search subfolders is checked and click next to install. two more drivers will pop up in device manager after u install the first one. Repeat the same procedure for both of them and then you should be able to use adb just fine to root.

Just wanted to further confirm that using a different microusb cable works! I keep reinstalling the drivers but it kept showing the device was offline. Then I tried my old Nokia N85 cable and it worked like charm! So weird how usb cables aren't made equally, unless Samsung designed the cable to prevent using adb?

I had this issue for a little while, but I installed the Samsung Kies software (which contains drivers) and uninstalled the ADB drivers I had originally downloaded. It's worked like a charm since then.
Go to SamsungApps.com and then use the canada site, as the software isn't really available in the US yet.

I have had no problems using the stock cable on my Laptop and work PC, both are Win 7 32bit. The same cannot be said for my my main home PC which is Win 7 64bit. Neither the stock cable nor an after market cable worked with ADB.
For the 32bit OSes I installed the Kies software and the usb device gets installed correctly. for the 64bit OS, I installed the Kies software but could get the phone to connect correctly. I then tried to install the 64bit drivers that are floating around the web. The 64 bit drivers worked enough to get the phone connected to the PC but when I tried to query "adb devices" the phone would always appear as offline. I've tried several things: install/uninstall drivers and software on the PC, restart the PC and Phone, change cables. Nothing seems to help on Win 7 64bit.
It seems to me that there might be a bug in the 64bit driver, though I have no proof of a bug.
I am going to keep playing with the 64bit OS until i figure it out or get so annoyed a that I just give up.
I'll be using my Win 7 32 bit laptop until I get the 64bit PC to work.

i've been able to install .apk's with my win7 64-bit ADB :O
all i did was install Samsung Kies.
i don't think i've ever had a problem...?
EDIT: i'm using the cable that came with it and no problems yet.

I'm running win 7 x64 and Kies did the trick for me. I haven't had a single issue connecting my phone since I did that.
Sent from my SAMSUNG-SGH-I897 using XDA App

Justa dding to the anecdotes.
I was having problems with the included cable using the front USB. It would show as Device Offline, also the charging wasn't very strong.
I switched to the onboard USB at the back of the case, and adb worked fine with the included cable.
Looks like I'll be picking up a couple extra USB cables so I won't have to continuously do the desk dive everytime I need to use it somewhere else.

1. I installed the kies drivers first and it would say offline when i checked the device through the cmd prompt.
2. I then installed the adb drivers and it then said the device was online.
3. i then rooted the phone and went on my way. i then tried it a second time and it said device offline.
4. nothing changed during this time except that i turned off debug mode, changed it to mass storage and plugged it back into the usb to transfer some files.
5. on returning to debug mode it no longer tells me the device is online. i have tried different USB ports as well.
6. i deleted the drivers, and reinstalled and it still says offline.
very frustrating.

wow. i forgot to try plugging it into another USB port. that worked. sorry about previous post.

I am running Windows 7 Home Premium 64bit on my laptop,
I installed the samsung 64bit drivers, it was an installer i found on the web, not the kies installer packaged driver one.
i changed my setting on my captivate to Mass Storage.
I mounted usb and everything works, by that I mean i was able to ADB like no tomorrow without any issues.
Then I made the mistake of installing Samsung Kies and that messed up my previous drivers and I wasnt able to ADB to my phone. I had to uninstall Samsung Kies and my phone still wasnt being found I still couldnt ADB.
my solution to fixing was restarted my phone and computer, without my phone connected to USB i re-installed the Samsung 64bit Driver Package, then hooked up my phone made sure Mass Storage was selected and Mounted USB and bam was able to ADB again.
hope this helps! also i have been doing videos helping people with issues with samsung's captivate on youtube, youtube.com/johnnyzappone if anyone wants to check em out, if anyone has any suggestions please let me know and id be happy to release a video!

I resolved my issues, I plugged the stock cable into one of the rear usb ports and the device is now available on my main PC Win 7 64 bit.

Confirmed this made my device stop appearing as offline with adb.
How it is even possible that the cable prevents (only) adb access on the PC, I have no idea.

I have windows 7 and mac osx and I can use adb with both using the stock USB.
i have debugging active.

lol @ the samsung cable.
i've 2 indentic cables here, one doesn't work. plugged in the other one and this one works...
maby its just a strange issue on windows, next time try to pull out the cable and put in back in then connect your device again this should work.... :s
because earlier the cable just worked fine and now it doesn't.. so good luck xD

WP8 is not detected by my computer - does not appear in windows explorer

My HTC 8x for T-Mobile doesn't show up in windows explorer. It suddenly stopped after working perfectly from the day I got it. I thought it may be my computer, like a missing driver or a setting but it doesn't work on my work computer, while my friends lumia works perfectly on the same computer.
Did there a setting I switched off in the phone?
I really don't want to hard reset cause I have so many email accounts set up with the phone. Any help would be great!

http://www.windowsphone.com/en-us/how-to/wp8/windows-phone-app-for-desktop
or try to delete driver and reconect phone.

didn't do anything. Plus it doesn't work on another computer that detects my friends lumia.

Anyone have any ideas? Please any help?

I had this problem on my computer that was previously connected to my Lumia920, and the second time I have connected it, nothing detected. I just plugged/unplugged the device several times, and after 5-6 times, there it was. Is ur device functioning properly? Is there any sound of connection from ur computer when u connect ur device?

Is your phone locked, by chance? I noticed that if the phone is locked it will not expose the file subsystems unless its unlocked.

some people have also reported that using a different usb port in your computer also helps.

Make sure you are using short USB cable that is working with another phone. Half of problems i have with computer "not detected" phones was due to low quality USB cables and under-powered USB ports, especially ones located at front of computer. Try to experiment with different USB cables and USB ports on different computers, this sounds stupid but helps in half a cases .

I have some problems with my Lumia 920 when the cord is to long!
Try to use the orginal cord!
Hope it helps

Watch for Memory card!
Hi,
Try to remove the memory card and reattach the device.
It solved the problem for me and read on some places about it.
Be careful what size and 'shape'(brand) memory card you use as it can block usb usage as it seems for me.

Method 1:
Disconnect all the external devices (printers, scanner, USB (Universal Serial Bus) drives, etc...)Except mouse and the keyboard and then boot up.
If this corrects the issue then add the devices back one at a time until you discover the piece of hardware causing the issue. Then get any updated drivers\software for the device.
Method 2:
If you still come across the issue, I suggest you to run Hardware Troubleshooter and then check for the issue.
Method 3:
If the above step does not help us to diagnose the issue, uninstall the drivers for USB [Universal Serial bus] host controller and restart the computer. Let Windows install the generic drivers and then see if it helps you to fix the issue.
a) Open Device Manager by clicking the Start button, then Device Manager in the search box.*
b) If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
c) Look for the device under USB [Universal Serial bus] host controller, right click on it and select Uninstall.
d) Reboot the computer.
e) On reboot, Windows 7 should re-install the drivers automatically.
You may also refer the steps from the manufacture website or contact Nokia for any known issues.

Try installing the Nokia Software Recovery Tool or the Nokia Care Suite. It should install all of the drivers necessary to connect your device. There is probably a driver corrupted.
the question you need to ask is if your friend has the same model Lumia as you. If he doesn't, it could be a problem with the driver on your PC.
If he does have the same model as you, it has to be a problem with your phone. You need to do a factory reset.
Have you checked if it works with the Windows Phone app?
Also, there is really no reason to have a need to connect it to a PC. As long as you store your documents and photos in OneDrive, you can easily access them from your PC without having to connect your device.

Thank you for the repose, i tried the same but still it did not workout .

Try another USB port and/or cable

You don't need HTC Sync or HTC drivers for this. Windows has it's own MTP drivers.
I would try uninstalling the HTC drivers, in case they are causing a problem.
Plug the phone in, and check the Event log in control panel to see if anything is flagged.

same issue faced
So did this issue get fixed for you? i am facing the same issue with my HTC One E8 dual sim. and cant seem to find a way to get it fixed.
