[L7] Problem with USB connectivity / drivers

Hi
I'm having some problems with connecting my P700 over USB. I have the official JB ROM now.
On my desktop computer, when I connect my L7, nothing happens. The phone starts charging (slowly) and nothing else happens.
I have installed/uninstalled the USB drivers several times, tried every connection mode, used different cables, and still no connection.
BUT my phone connects fine to my laptop computer, I just installed the driver and it works good.
The laptop has Windows7 32-bit, the desktop Windows 8 64-bit.
Is there anything I can try for the connection to work on my desktop without formatting it? Please help me. I've ran out of ideas....:crying:
Thanks

The steps are good, you have to make sure you are in USB Debugging and connected for LG Software.
If your phone is not detected and there is no attempt to search/install drivers automatically by your PC, try installing the drivers in attachment. Now restart your PC and try again, it worked for me, hope it does for you.

I had the same trouble,I connected my phone with Lg software, it auto downloaded driver and installed

Is MTP activated? Go check in Settings>Storage, touch the three dot overflow and go to "USB Computer Connection". Make sure MTP is checked. You can also try PTP mode too. Good luck!

You have to install LG L7 driver on PC too. I think the name is "LG PC suit" or "LG mobile update"

[Q] Windows doesn't recognize my A500 through usb

Ok so I think I've searched well enough to conclude no one has my particular problem. When I plug in my A500 into my computer that has windows 7 windows recognizes that something was plugged in but not what it is. It says USB device not recognized, unknown device, and so on. I've tried installing the drivers from the acer website, I've tried installing the drivers from the link in the ics rooting thread, I've tried using the google android drivers and none have worked. I've even tried reinstalling windows but that had nothing to do with this it was a different thing that made me do it. Nothing has worked and I've become a bit frustrated with the tablet. Any suggestions on what to do?
Thanks

What state are you connecting it in (recovery, fastboot, normal boot)?

Moborobo test program

Sorry forgot to say, it's stock rom not rooted and is being connected in normal boot.

Your computer isn't detecting it at all, or is there an error while trying to identify it? Make sure you have the proper drivers for your device on your computer.

It's an error identifying it. I do have the correct drivers the a500 drivers from either the rooting guide or the Acer website neither has worked.

Moborobo does not work with the a500. I tried it and it still says to connect my device. which it is but it's just unrecognized.

If you have installed the driver correctly, AND you had administrator rights when you installed, should be no reason why you can't get the PC to recognize the device.
First, I would advise using a good USB cable. It's been known in the past, that some folks try to use a printer cable, and sometimes it doesn't work. If changing cables doesn't work, then do the following
1. In Device Manager, try loading the drivers manually. You should be able to have it search the windows system for the drivers. If it doesn't find it, then windows is being stupid. Try installing it manually (ignore the warning it may not be compatible,.....)
2. If that doesn't work, then you can use the Google USB drivers
http://www.redmondpie.com/android-u...r-samsung-htc-asus-sony-lg-and-other-devices/
Generally, we install the Android SDK first;
http://developer.android.com/sdk/index.html
And again, have Device manager look to that directory and manually select.
Either way, this should get you up and running.
And one more thing, turn on USB Debugging in your tablet's system properties.

I've tried that. Didn't seem to work as windows would still not recognize the a500. And the usb debugging has been on since the beginning.

Okay i've gotten windows to the point of being able to install the drivers from the device manager but there is no clear option to choose. Here are the choices:
acer android communications port
acer android modem
acer hs-usb android diag
acer hs-usb diagnostics
acer composite adb interface
acer fastboot interface
acer picasso usb boot-recovery driver (google driver)
android bootloader interface (google driver)
So any suggestions cause I've tried installing the adb interface, fastboot interface and the android bootloader interface and haven't gotten any good results.
Thanks

Did you try a second PC? Sometimes a machine can get wonky if you've been using for years. Using a second machine or reinstalling Windows freshly would greatly increase the chances of detection.

Yep tried about 3 machines.

I'm having the same issue with a bricked A500 I bought on ebay
Windows just recognizes it as an MTP USB device and fails to install the drivers
I have another A500 that comes up fine as an A500 on the same PC.

Try disabling the USB debugging in developer options I have the same issue with my Win 7 x64 system

Cant connect to laptop?

Trying to connect my LG G2 to my Acer Aspire V laptop and I cant get anything out of it. I've installed the drivers from LG's website, I've tried installing LG pc suite(works via wifi. The phone thinks its connected via usb but the software doesn't see it). I've also tried manually selecting various LG drivers and it still won't come up. My laptop is windows 8. On my windows 7 desktop the first time I plugged it in it came up like a usb drive and connected perfectly to LG Suite.
Any suggestions? I am with bell.

bump~~~~~~~

bump............

Other than trying to completely deinstall all drivers, software, and then installing PC Suite again, I don't think there is a lot you can do.
Does Windows give any sort of notification about Device problems, or failing to install drivers?

MTP Mode not working

Hey,
So I got my D802 today and I want to do the whole Root, Recovery, ROM shenanigans.
But for the love of god I cant connect the phone in MTP mode, so I cant Root, nor install a recovery.
I cant connect to the LG PC Suite either.
Any Ideas?

what connection type are u choosing after plugging it into the computer? are u running Windows, Mac, Linux? Windows will work with mtp out of the box but I think Mac and Linux need phone drivers installed. Windows will need drivers when you're ready to "unlock" using adb.

Right, so I´m running Win7 64 Bit
I tried multiple USB Ports, rebooting PC and Phone, resetting Phone and now i´m all out of ideas
I never had any problems with the other phones I rooted and unlocked on this Computer

when you first plug in your phone it gives you the option to install the drivers needed to connect in the different modes, if not on the top right corner of the menu with charge/mtp/pc software it should have the option to install the drivers

you never said what connection type you're choosing on the phone after plugging it in. there are a few options and change how the phone is seen by Windows. some options won't have it display as an mtp device or as a drive letter in my computer.

Really Weird
I'm having the same issue. I'm running OptimusG3 v1.3, I've never had an issue with it before, I used MTP to transfer files yesterday, worked flawlessy, now it won't. I was trying to map the G2 as a network drive, I installed LGPCSuite, a couple of other software that should be inconsequential, and suddenly my phone says connected as MTP, but my laptop won't recognize or show the device in My Computer. I get installing device drivers prompts, I used the hardware and devices troubleshooter which told me 'LGE Android MTP Device has a driver problem' and LGE Mobile USB Modem has a driver problem. Reinstall device driver -> completed, but still not fixed. I installed LG's universal uSB tool or whatever, no fix. I have no idea wth is up (It's not a USB debugging accidental toggle either). I'll try uninstalling PCSuite. I though it would be more useful

[Q] USB Automatically Disconnecting after two sec.

I am not able to connect my phone to my pc using data cable neither in Download mode nor in Power on.
The problem is that USB disconnecting automatically after two sec, and windows was unable to recognize it.
I tried connecting Another phone using the same data cable and pc, it worked fine, it was GTS 5830i.
is there any way to solve this issue?
please help me.

What operating system are you using?
For example in Windows 8.1 you need to do the following
Download USB drivers (see my firmware thread link in signature or at top of dev section)
Right click the setup file
Click properties
Select compatibility tab
Select run this programme in compatibility mode for
Select windows xp sp3
Select apply
Run the setup
It will now run & install
Note any other operating system just run the setup normally
Now plug your phone in via usb
Now plug in any other USB devices eg a wireless mouse dongle
Windows 8.1 will now recognise the device

I am using windows 7 ultimate.
By saying im able to connect other phone to the Pc, I mean all USB Drivers are
Correctly installed.
I think its a issue related to my phone, us there any settings to change? Like *#7284%?

Check to make sure there is no dirt and debris in the USB connection on phone - you might want to clean it with cleaning solution (whilst the phone is off)
Other than that you can flash stock rom via odin to make sure there are no software problems with phone
There's no settings as far as I know that will stop USB connecting unless you have deliberately looked for & changed something relating to it but I can't think of anything

Well I am not able to connect to odin.
Now i use a custom Rom i just want to install original rom using odin.
i tried cleaning USB port,

If you have
Installed the USB drivers
Using Odin version 3.07
The firmware from my firmware thread
Using rear USB ports if on pc
Put the phone into download mode (Vol down home button power button)
Pressed Vol up in download mode to start connection
Then the only thing left is a hardware fault or user error - both of which I can't support here
