Computer doesn't detect my TC!

When I connect the cable from phone to PC, my PC says that there is a duplicate name on the system.
And in My Computer, there is a Mobile Device icon regardless of the phone being connected or not.

This might happened after Windows XP SP3 installation (or after Vista SP1).
The solution is to uninstall ActiveSync 4.5 and reinstall it again.
Regards
PS: anyway last ActiveSync 4.5 will behave funny since it is not compatible with XP SP3.

I've tried reinstalling, but it didn't work.
I am using Windows XP SP3, indeed, does anyone know of a way to get around this?

Try these tips one by one to see it any solves your problem:
1. Open the connection settings in activesync and double-check that USB connection is checked.
2. On the phone try click Start -> Settings -> Connections -> USBtoPC and uncheck the checkbox "advanced network...". (or check it if it was unchecked)
3. Unplug the phone, rename c:\windows\inf\infcache.1 on you computer (not phone) to infcache1.bak or something similar.
Replug the phone. Windows will now re-detect all USB devices and reinstall the drivers. If it did not help you can always rename the file back and you have lost nothing in trying.

After Step 2, the "duplicate name on the system" error message did not appear.
However, even after step 3, the Mobile Device icon still exist and I am still not able to access the contents of my phone through my PC.
Is it because my computer's name is the same as my phone?

Perhaps Try and rename the mobile, no hurt in trying.

Thank you very much, but I finally find out the problem on my own.
All I had to do was to Enable synchronization of all PCs using the "`USB" connection when craded under the ActiveSync Connections on my phone.
Thank you for your time.

Good that you solved it in the end.

need help pc dosent recognise my device x7510
it worked before tryed everthing on the posts on this section

Is your device recognised on any other PC?

wmdc in window 7 64 bits

Hi All!
I've just changed from Window XP to Window 7
Unfotunately...
activesync is not working on Window 7 anymore...
I've install WMDC for Window 7 ,64 bit
but after the installation, and i plug in my phone,
a process for searching the driver loads for a while
and said: driver not found
The WMDC has no response when i plug my phone in.
I have tried different methods that i can search on the web:
1) remove device+uninstall WMDC + reboot + plugin and install WMDC again
2) disable the advance network function
but no luck...
I can connect my phone as a "USB drive", but what i want to do is to let my phone surf the internet through the PC... so I need something like active sync... can anyone suggest other alternatives which can fulfil my needs...or can anyone give me some tips on how to connect my phone to WMDC>.<
Really need help...SOS...

I encountered the same problem going from XP to 64bit Win7. I manage to solve the problem.
1. WMDC is not installed as a default during Win7 install. It is installed via Windows Update.
2. After this, WMDC will come on if u plug in the PDA but gives u an Error after trying to connect to the PDA for a while
3. Here's the solution. Go to COntrol Panel/Device Manager. Open up the list of devices installed. Plug in your pda and notice a new device is listed as "Unknown device" appears under the Device manager tree.
4. Click properties of this unknown device and choose to upgrade the driver. You will need internet connection for Windows Update to download the device driver. This driver is about 11.9MB file size.
5. After download, re-connect the PDA and it should recognize the PDA immediately.
I also noticed that if I plug in another PDA model, it will also connect and work.
Hope this helps.

I have do the same many times ...but still no luck...
what is your phone model?
I have sent an mail to Asus, ans it said there are no driver for window 7 64 bits for my phone model..... only have 32 bits...

[TUTORIAL][ADB][WINDOWS 8]Connect HTC explorer to windows 8 and use adb

Hello friends,
This is my first tutorial on this forum and wishing to help my buddies overcome a simple issue I've been facing for many days after coming to windows 8... I am a regular Android App developer and when i started using Windows 8, I observed that the default adb interface couldnt detect my phone.
After a lot of searching here and there, I realized, that there is something missing. So here comes the way to connect our baby droid to the all new windows 8 -
THINGS YOU NEED -
HTC Sync latest 3.21.1
ADT - you can download this from android site.
and this file
NOW HERE COMES THE PROCESS -
1. Download and install HTC sync.
2. Unzip the ADT and add the platform tools folder to your environment path
3. Unzip the file downloaded from link above. Basically its the google usb driver.
4. Now go to device manager and see your phone should be listed as an unknown device.
5. Now find "Android Phone" with a yellow error sign in front. It will be expanded by default.
6. Right click on it and select update driver.
7. Select browse my computer.
8. Link to the folder where you extracted the google usb drivers in step 3. Check the subfolder.
9. Click next. It'll display a warning. Select Install anyway.
10. Completed.
11. You may now download SDK and ADB.
Hope this would be helpful in someway or other.... :highfive::highfive::good:

Is it necessary?
Do we really need HTC sync if we are on a custom rom?

Idea of htc sync is to have htc drivers, it is even recommended to stop htc sync when doing something with adb

Yes htc sync is not needed, but sometimes I see that if my phone is not being detected on adb and i turn on htc sync and keep it aside, my phone gets detected. So I am also a bit confused if this is at all needed or not...

just update htc sync (in case if it is not ) cuz i did the same and my phone got detected in windows 8

Can't get internal SD to mount on computer

Nope, still nothing. My Razr HD comes up fine, but not the Nexus 5. Think it's a conflict in drivers?

definitely...the only time i ever had Nexus driver issues was when i changed from HTC to Nexus
the best i can offer is how i fixed it...get a copy of Wug's Nexus Root Toolkit and follow his instructions from deleting all other drivers and installing new ones...he offers (i think) 4 different options and you just work your way through them until one stick (the RAW drivers always work for me)
and note that the Toolkit doesn't work on 4.4 yet, so only use it to clear and update drivers

Sweet, that did it. Uninstalled Motorola drivers, uninstalled Google ADB driver, restarted, plugged in phone, voila!

Thank you n7of9 the link you provided worked for me.

Another solution...
Plug the phone into your computer. Go to "Device Manager" and find the Nexus <x> device where-ever it's listed (may not be called "Nexus...", though on my machine with the real drivers it was).
Right click, choose "update driver software"
Select "browse my computer"
Select "let me pick..."
Choose the option. "usb composite device"
Apply and close all windows.
Disconnect and reconnect the phone to the computer.
The phone will now allow you to move files to it properly. Something weird with proper phone drivers. I believe you need to reverse this if you need to use ADB again in the future.

This worked and also fixed another popular issue
Not only does this fix the MTP connection issue to move folders to root folder. But it also now allows me to see the preview thumbnails of my media! This was a huge problem on my other phones and many many people including me were never able to fix that. All the ideas to get around or create USB Mass Storage instead of MTP after 4.1 were fails.

Worked perfect, thanks

what worked for me
In windows 8.1
I plugged in my nexus and browsed to device manager in control panel
I uninstalled the device (and deleted the driver)
I unplugged the nexus 5
I plugged it back in
Windows recognized it as a proper MTP device
I think the problem was something to do with windows recognizing it as an ADB device (I had installed the toolkit before etc)
This fixed it for me

Hi,
I did all the steps mentioned, and ran the driver test - everything works fine, success.
However, I still cant see my device in "This PC"...
What is even more weird, that it only disappeared couple of days ago, and I didnt do anything to my computer at all....
Any other way to get devices to show? (Nexus 10 or Nexus 4 stopped showing too).....
Maybe problem is that it is being shows as ACER ADB Interface? But i cant change that to MTP anyway..

[Solved] USB suddenly stopped working

I have a Nexus 5 that I have had about a month now and I had the USB on it working before about a week ago. I plugged it in today and neither my desktop or laptop could recognize it anymore. Both computers are running Windows 8.1.1 and the issues seems to be new as I can neither get USB storage or ADB to find it. The closest I can get it to working is to switch the USB mode to PTP and it reads that but I don't want to pull photos off. When I have it in MTP, it makes the sound of it plugging in and my phone shows it is plugged into a computer but Explorer shows nothing and it says it is working normally in device manager. I've tried everything from enabling and disabling debugging, restarted both my phone and computer tried reinstalling the drivers (both by the computer automatically finding them and manually installing them) but nothing seems to work. Is it possible that Windows Update could of broke the drivers since my computer installed updates yesterday? I also have Linux on my laptop and it appears to read fine with Linux.

That's the exact issue. If you check in Device Manager you'll see it listed as 'ACER ADB Device' (or something like that). You have right-click on it, select update driver, manually check and go through the list option and choose the MTP driver and it'll work again (and with USB Debugging enabled if you don't usually have it on like me)
I theorise that it's happened cause the Acer driver is digitally signed and the Google ones aren't but I could be wrong. Either way, it's a PITA

OK thanks. I'll give it a try because it was showing up as ACER ADB Device under device manager
EDIT: I updated the drivers and used the USB composit drivers instead and it got MTP working again. When I set it to USB composit, it installed Google's ADB drivers and the Nexus 5's USB drivers so everything is working again. Thanks for your help

I can´t manually update driver because of this:

when i update the acer adb it says the driver is up to date and everything is all same. what to do?

Thanks! Thought I was going to go crazy. Worked for me...

i set the driver to MTP as mentioned above and the phone started to show up on the explorer but now i couldnt copy any files from my laptop to the
phone. It displays like that and if clicked yes then the copy wouldnt happen.what is the problem.

Uninstall driver, plug in device, tell windows to not auto install driver (or disconnect from internet), click to update or install driver, point to folder with drivers, install, all is done.

That msg comes when you're in PTP mode I think...Only certain formats are supported.
Check under storage, expansion menu and make sure you are set to the first option...not PTP.
Above guy mentioned to have phone in USB debugging mode when setting up drivers.

If the device is showing then you need to point to the drivers for it (download them from google). I reinstalled windows a few days ago and had the acer issue (device first shows up in device manager as nexus 5 then switches to acer), windows wants it to be an acer device. Stop windows and then install the correct drivers,
For me I had to click the auto install in windows tray and tell it to stop. After a few times it worked.

No I'm connecting in MTP mode. Ahh its gettn irritating.
