myTouch 3G will not connect to pc other than for charging

I bought a used MyTouch 3G with the 3.5mm jack. Everything seems to work, except for connecting to either of my windows 7 pc's. I have the oem usb cable that came with the phone. When I plug it in, Windows says the usb device is not recognized and is malfunctioning. I attempted to install the drivers that come with pdanet to no avail. I also installed htc sync. When I plug the phone into my computer, it starts charging, but the taskbar message on the phone does not show it as connected to a pc.
Any ideas here?

try another usb cord?

Try to install the USB drivers that come with the Android SDK?
(I don't think you need the HTC sync stuff for that).
Depending on what ROM you are running, or if it was made by some paranoid network provider, you might not be able to use the phone as a modem (tethering)... I've heard that some network providers disable the tethering feature...
With CM ROM, I've had no problems tethering over USB in: Windows Vista, Windows 7, Ubuntu 10.4 (Windows XP didn't work at all).
You have to enable the tethering feature first on the phone before it will work (I'm not talking about installing some app from the market, I'm talking about the built-in setting: settings-->wireless&networks-->tethering).
Have you tried mounting your SD card to access it as storage device over USB?
If neither tethering or USB mount wants to pick up when you plug the cable in, I'm guessing your cable is bust or your phone...
Have you tried the same cable on another PC?
Are you using some dodgy USB add-in card or USB hub on your PC? Did Windows 7 install the correct drivers for your USB controller on your motherboard? (do any other USB devices work on your PC?)

same problem HTC my touch 3g
I have a google tmobile htc my touch 3g 32B 2.2.1 android and under vista i have a load of usb problems device not recognized. have tried many many things still nothing works. called htc they told me to call ms. perhaps some conflict with the device. problem rooting it with sapping and gold card method and sapping as well. any suggestions?

Maybe you have a corrupted misc partition :0|

just restart your phone... it will surely work

When I connect my phone with USB-Debugging enabled I get a message from Kies: "Reconnect your device in the Samsung Kies-(PC Studio)-mode again. The current connecting mode is not supported by Kies."

I'm sure you have already tried this....but have you plugged the usb cable into a different slot? preferably one at the back of the Pc. My phone wont sync with Kies if I have it connected to the front slots.

Still doesn't work.

Open kies.
Instal drivers from the menu.
Wait until it says complete. A couple of times it did not bring up the instal dialogue box. Keep trying until it says drivers installed.
It will then work. I had this problem on both xp and win 7. This sorted it.

It installs the drivers. The problem is, once I uncheck the USB debug mode and reconnect the phone it installs the drivers again and fails.

Plug your phone into the PC, turn off USB debugging & select USB tethering. See if it installs the driver that way. Also do this while your PC is connected to the internet, when/if it fails leave it plugged in the PC and check windows update to see if you need to download an update for the drivers.

Still doesn't work. I did a Windows Update.
Gerät entfernt means device removed and Fehlgeschlagen means failed.

Guys its simple.....i was also facing this problem. just unchecked USB debugging mode....and try to connect again. Its Done.

Another useless thread...

Halp! Windows 8.1 upgrade at war with n4

Hi,
I had win 8 in which I was successfully able to do everything with my n4 (adb connections were good and so was MPT). I updated to win 8.1 and now it's derping out. ADB drivers seem fine. I tested it by simply running adb shell in cmd prompt, but even though my device is connected, it says that it's unable to find device.
Whats more important to me is that the device is not showing up in my computer. Although windows plays the usual usb connection sound. I'm also able to see it has detected my device as Nexus 4 is under the unknown device category. How can I fix this. I relly need to transfer a few things between the comp and phone, and it kinda sucks at the moment.

Just format it and install Ubuntu!!!
lol, just jocking. if adb is working you don't need it to recognize it. You can just use adb push/adb pull, but anyway.. did u try to enable debugging?

It means something has derped with the mtp driver
Open up device manager
You will see your nexus 4 with a yellow exclamation mark next to it
Right click and update driver
Manually choose
Then you will have to scroll through the list and find the mtp device (I can't remember of the top of my head exactly which headers it is under)

Connect your Nexus 4 in USB debuggin mode and uninstall your current driver in device manager checking the 'delete the driver software' option.
Download Universal Naked Driver: http://forum.xda-developers.com/showthread.php?t=1379875
Reboot Windows 8 into advance mode and select to disable driver signature: PC Settings -> Updates and recovery -> Recovery -> Advance startup -> select F7 option at the selection menu when you see it
Reconnect Nexus 4 and install it with UND driver.

Thanks all! I just uninstalled the current drivers and reconnected the device. Windows picked up on the right drivers. All ok!

Cannot connect to LG PC Suite

HI,
I'm facing an issue while trying to update my LG G2 to 4.4.2. LG PC Suite cannot see the device when connect with PC Suite mode. There is an icon in the phone notification bar saying Phone and LG PC Suite are connected via USB cable. The PC Suite itself keep trying to connect and after few seconds, it will show this pop up.

I'm not quite sure why the PC Suite keep asking me to install MTP driver because I can see my phone in the window explorer and device manager, I can transfer files between PC and Phone when connect with MTP mode, I can tethering the internet connection ... basically, I can do everything I'm suppose to except connect with PC Suite. Any idea or suggestion are welcome
Some Info
- My LG G2 is runing 4.2.2 (D80210e-ESA-XX)
- I'm using Macbook Pro Retina Late 2013
- Bootcamp with Window 7 Ultimate 64 Bit
- This is my first PC Suite connection with this Macbook
- But, I've been using it to transfer files (with MTP) and share internet for few months so far (still able to do so at the moment)
- I can connect to PC Suite MAC but it always failed to connect to update server so I have to try with window.
- I think cable and USB port is fine since I can do file transfer and connect with MAC PC Suite.

Same problem...
The same issue, but I had been using PC Sync for a month on Win 7 flawlessly before I have done (F)OTA upgrade to KitKat on LG G2. Since then I could't estabilish PC Sync connection with my phone. On the other hand I'm still using MTP for normal acces to device storage. Trying reinstall drivers and programs for 2nd time to get it solved with no effect. Have no clue what's wrong. Have anyone reported bug to LG with any response?

+1
the same problem. my phone will show only bettery charged and nathing elsa

any luck ?
Any luck for some of you. I am having exactly the same problem.....
thx for your help !

I am having same problem... cant connect with PC suite or OSP or LG Mobile support tool

Why the hell do we even have to his a 250meg "PC suite"? Why cant we just mount the damn thing as a USB device like every other phone/rom?

If you're still on KitKat just use On Screen Phone, that usually works no problem. I could never get my phone to connect to PC Suite, not with KitKat or now with Lollipop.

[GUIDE] Fixing Windows 10 doesn't recognize MTP mode when USB is connected

All right, so you have updated your phone's ROM or you have purchased Windows 10 Pro, you plug your USB cable from the phone to the computer. Phones get charge, if you choose PTP (to transfer photos) it works, but if you select MTP or USB storage you hear a sound like if you had disconnected the cable and phone is not recognized.
This is related to a driver problem. To fix it:
1 - Plug the USB and select MTP connection
2 - Go to your Device Manager (Press Win+R, on the search box write "mmc devmgmt.msc" without quotes). You can use any other way you know to enter D. Manager.
3 - You should see something similar to "Portable devices". Display the flange (if not).
4 - Now right click on something similar to "Unknown Device" (yellow highlighted text) with a yellow tringle in the icon.
5 - Choose "Update driver software"
6 - Select "Browse my computer for driver software"
7 - Select "Let me pick from a list of device drivers on my computer"
8 - You get a list with a lot of possible drivers.
9 - Choose Mobile Devices/Android Phone/Android USB Devices (you should have at least one of them)
10 - Select "MTP USB Device" from the second screen's list of drivers.
*If you do not see Portable Devices in Device Manager then maybe you don't have installed drivers properly. In that case, first download drivers from here and install them. Then follow this guide.
Some screenshots of the proccess (it is in Spanish but what you have to do is the same and is translated in the steps).

That is the most common solution to the problem. If your problem is not fixed with that, then try this:
Published on Microsoft Answers:
Question:
After anniversary update, MTP is not working.
I tried with different devices as well as on many PCs.
In device manager I get this:
The drivers for this device are not installed. (Code 28)
A service installation section in this INF is invalid.
Click to expand...
Click to collapse
Solution:
1 - Go to C:\Windows\INF
2 - Type "wpdmtp.inf" in search bar provided to the right of the address bar in Windows 10.
3 - Once you found it, just right click on it and select install. It will take a very few seconds.
4 - Connect your device to the pc. It should be recognized now.
I hope this can be useful for you.
