No USB Connection

Hi,
I have a Diamond which I've recently flashed with Gen.Y's R5 NLD rom and radio 1.17
At first everything was fine. However, since a few days when I connect the diamond to my (windows 7 x64) PC I get a message "USB Device not recognized". I've reinstalled Mobile Device center to no avail.
I've also tried unchecking "Enable advanced network functionality", but that neither helped.
Luckily I can synchronize activesync through bluetooth, but it's really slow, also for files.
Internet connection through USB works fine though.
Anybody got an idea what I could do?
here to help
1. make sure you have the latest windows mobile device center
2. plug the device into usb port
3. go to control panel administrative tools - computer management - device manager
4. click on universal serial bus controllers and uninstall any usb root hubs and usb composite device
5. unplug the device
6. restart the computer
7. plug in your device

USB Connecting Problem - Android 2.2.1

I installed xdandroid 2.2.1 and everything works fine (except camera i saw that this is fixed with karnel update but I don't know how to do that) and i can't connect usb to PC.
I try install driver with Android SDK but it can't install CDC Abstract Control Model and CDC ACM Data drivers. On notification bar say that USB is connected and USB debugging is connected .Also I install HTC Sync it install all drivers except CDC Abstract Control Model and CDC ACM Data.
I also done this :
adb and usb debugging
To ensure that you are able to use adb and usb debugging you will need to plug in your usb cable to your computer and in winmo select activesync. Now launch haret and once Android is loaded you'll see a notification that will notify you have usb-debugging control and able to use adb.

Optimus 2x + PC Suite IV

For some reason mine won't sync? I can use the phone in USB mass storage mode, but if I just connect it to the PC and open PC Suite, it says "Connecting..." and, after a few seconds "Device is not responding".
I have the "USB Mass storage device only" option unchecked in the phone's settings.
I installed the USB drivers using the LG Mobile Support tool by entering the IMEI # of my phone. I tried reinstalling the drivers and reinstalling PC Suite but still nothing has changed.
Any ideas? I'm running Windows 7.
Try to unlock the screen of the phone and reconnet it again!
Check your devices info from the control panel and see if the device is recognized correctly (driver, status, etc..)

Doesn't make a difference.

I see:
- LG Android Phone
- LG Android (Modem)
- LG Android (NMEA)
- LG Android (Serial)
- LGE P990 USB Device
In my device list. For what it's worth, I rooted the phone and I think it worked fine before I did so, because I remember getting it to work once when I first got the phone.
I'm also unable to update it using the Mobile Support tool, it gives me some kind of critical error and tells me to remove the battery and try again (which doesn't help).
´I have the "USB Mass storage device only" option unchecked in the phone's settings.´
PC Suite IV works well for me.
My settings:
USB Mass storage - off
USB debugging - on
Stay active - on
Others as usual...
rooted P990

Problem solved.
It's because I froze "LG PC Suite" using Bloat Freezer.

[Q] USB Mass Storage Device driver failed

Bought a LG P970 Optimus Black.
Installed LGMobile Support Tool into my
Windows 7 64bit.
Installed the LG 3.2.1 drivers using LGMobile Support Tool.
Then, I connected the phone to the computer.
Result of drivers installation:
LGE Android Platform Composite USB Device - Ready to use
LGE Android Platform USB Modem - Failed
LGE Mass Storage Device - Failed
LGE Android Platform USB GPS NMEA Port (COM6) - Ready to use
LGE Android Platform USB Serial Port (COM7) - Ready to use
I wasn't planning to use the phone as a modem, so that driver does not worry me, but the USB storage problem is annoying.
In the phone, it does look as it connected. It offers the option to activate USB storage on screen, and if I click on the button, it says it enabled it, but nothing happens in the computer side.
I tested to uninstall everything LGE from the computer and restart from scratch, but same problem.
Ideas?
Update:
The LGMobile Support Tool in Windows says the phone IS connected, and that the software in the phone is up to date.
Do You see the phone into section computer like Removable Disc?

No. Nothing at all.
In "Devices and Printers" I have:
Under Devices:
LG Android Phone
LG Android (Modem)
LG Android (Serial)
LG Android (NMEA)
Under Unspecified:
LGE Bluetooth TransPort (COM4)
LGE Virtual Modem
In the "Device Manager" I have 1 "USB Mass Storage Device", with a yellow warning sign.
Under its Properties, in Device Status, it says: "This device cannot start. (Code 10)
If I try to "Update Driver" Windows says that the right driver is already installed.
FIXED !!
Updated LG driver to 3.5.
Still didn't work.
Then, I turned off the phone.
Removed the battery.
Put the battery back.
Turned on the phone.
Connected it to USB.
This time the USB driver started ok, and when I activated the USB storage I was able to see the drive under "Computer" in Windows Explorer.
I had turned the phone off and on before, so I think removing the battery did something that simply turning off and on wouldn't do.

I had the same problem and could not find anything. Then I also found that turning phone off and pulling battery worked for me also!

USB 3.0 External Storage Device driver not getting Installed- [Solved]
Issue: USB storage device is not working on my computer, be it a USB 2.0 or USB 3.0 it just doesn't install the driver for storage device and my USB mouse and webcam does work.Everytime I plug in a USB flash drive of USB 3.0 External hard drive it beeps and gives error message that the device driver could not be installed.
Here is the steps I took to troubleshoot this issue and it got fixed.
1.Open registry by going to Run-> Type Regedit.
and Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
Highlight this key ({36FC9E60-C465-11CF-8056-444553540000} ), on the right pane, and then check if “Upperfilters” and “Lowerfilters” value are present. If so, please right click on the values and select "Delete" to remove them.
2. Now go to "C:\windows\inf" folder and check if these three files USBSTOR.SYS, usbstor.inf and usbstor.pnf are available.If it was renamed change the name as I wrote them or if they are not available copy them from "C:\windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3"
And then go to "C:\WINDOWS\SYSTEM32\Drivers" and make sure you have USBSTOR.SYS and usbd.sys available if not copy them again from
"C:\windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3"
and paste it to Drivers folder.
3. Open Registry editor by going to Run-> typing Regedit and Navigate to the following key:
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR" and ensure that the Start value is 3. and restart the system.
It will work..
thx

please dont use any USB hubs...connect it to the USB port on the motherboard side....normally on the rear side for the Desk tops.....on the laptop all ports are directly connected normally...
secondly, what is your config? ROM?Kernel?please state your current configuration which can allow others to understand the situation.
Thanks
yeah i dont use usb hub i connect it directly i tried it on my laptop but its not working
my o2x dont say that usb debugging is connected it only charge
im on stock GB now 2.3.4 v20g
Don't want to hijack this thread, just got the same problem. (Not a complete noob here, rooted lots of different devices)
Bought a used 2x today. Froyo 2.2.2 german stock on it.
It just doesn't show the prompt that USB is connected
Tried:
- LG Mobile Driver from version 2.x.x up to 3.7.2
- on Win7 32 bit, Win7 64bit, Win XP 32 bit on various USB ports
- LG PC Suite obviously doesn't connect too
- checked/unchecked USB debugging, USB mass storage and all the obvious settings
- tried different cables
Would be really great if someone experienced could point us in the right direction.
EDIT:
After lots and lots of google I found out about a menu when dialing: 1809#*990#
With these options available:
CP Image Download
FET Disable
FET Enable
AP UART
CP UART
AP USB
CP USB
CP UART gave me at least a life sign once by saying that Windows wasn't able to recognize the device.
Is this issue really unsolvable?
Sorry for the bump, but I got some update.
when dialing the above mentioned 1809#*990# in the Port menu, switching from default AP USB to AP/CP UART gave me life signs.
After switching to AP UART I linked the Unknown device driver to lgusbdiag.inf located in C:/ProgramFiles(x86)/LG United Mobile Driver.
Suddenly it started installing it and is now recognized as: LGE Platform Android USB Device.
Once disconnected I lose USB again, I'm able to recreate the first steps though even in default AP USB mode by now.
The only thing I need USB for is for flashing a custom recovery but the only thing I don't have is ADB somehow : / Clockwork telling me: device not found.
Any help on this one?
any idea guys about my problem?
Have you tried my method?
After manually installing drivers with CP UART on, switching back to default permanently enabled access with default AP USB settings as well.
i tried that but it only charge
theres a weird thing in my cp when i switch to cp uart my o2x says it charging even i dont connect it to my pc or charge it
Ap uart - p990 / p999
I have LG P999. rooted and cyanogen.
None of the special DTMF dialing # codes is not working (also code changed from 990 to 999) (i sow some other in another posts)
is anybody know a way to change to AP UART by software (with eclipse...)
or with a special cable?
i need to use AP UART - meaning to have a serial com in AP(app).
Thanks,
Tamir
guys,
Have you tried to install MyPhone Explorer and try the same....it can connect your device via wifi,USB or Bluetooth....so some way should work....
any Android version above Froyo(included) should work....I use this always...one of very useful and bug free apps.
Try it
