    Yes it happened to me and it was because in hacking the phone's innerds, it triggered a mechanism in the phone that cut off all communication (and charging) to the phone. If you hacked it, and it has been switched, you are basically DOA. You now have a fancy paperweight.

Connect the phone while the computer is off. Power on teh computer and it should detect a new USB hardware device. You should then see two new drive designations. 1 for the phone's memory and teh 2nd for the onboard memory card if you have one installed. Remember for the first connection the computer must be off when you connect the phone.

My usb connector malfunctioning


Instructions
  1. 1

    Turn off your computer.

  2. 2

    Unplug the power supply, remove your laptop batter, and wait at least 30 minutes before returning the battery and power chord to the laptop. As explained by Trouble Fixers, a cache of data from your USB device is stored on the motherboard. This cache is not completely erased until the motherboard fully discharges following power-down. Once the cache is cleared, most USB errors will be fixed.

  3. 3

    Turn on your laptop computer.

  4. 4

    Try to use the malfunctioning USB port. In most cases, simply turning off and unplugging the laptop will help remedy the problem. If a problem persists, continue with Step 5.

  5. 5

    Click on the "Start Menu."

  6. 6

    Click to open the "Control Panel."

  7. 7

    Click on "System and Maintenance."

  8. 8

    Click on the "Device Manager." A new window will open that lists all hardware and external devices currently installed on your laptop computer.

  9. 9

    Scroll the list until you notice the heading "USB Root Hub." Click on this option.

  10. 10

    Select the USB port that reads "Unknown Device." All other, functioning USB ports should say "unused port" or list a specific external USB device.

  11. 11

    Right-click on the Unknown Device port and then select "Update Driver." According to the tech-help website, Amit Bhawani, this will trigger an automatic update of the USB drivers. If no new drivers are found, the old driver will also refresh and repair. In many cases, a malfunctioning port is simply caused by outdated driver software. With the latest drivers, your port can be used with current USB devices without any problems. If problems do reoccur, then the port may be physically damaged and you'll need to take the laptop computer to a computer repair technician to get a new USB port installed.

Cannot connect to computer


FIRST OF ALL, NEVER EVER PLUG IT INTO THE COMPUTER WHILE ITS ON. ALWAYS TURN THE PHONE OFF BEFORE HAND. AS FAR AS YOUR COMPUTER NOT RECOGNIZING THE USB CABLE, IT MAY ACTUALLY BE YOUR COMPUTER. AFTER ALL IF IT WAS THE CABLE, YOUR PHONE WOULDN'T CHARGE SINCE IT IS THE SAME CABLE FOR CHARGING AND USB CONNECTIONS. MY COMPUTER HAS HAD TROUBLE SEVERAL TIMES WHEN PLUGGING IN NEW OR DIFFERENT DEVICES INTO THE PORT. TO CHECK THE USB PORT ON YOUR COMPUTER.... GO TO CONTROL PANEL, THEN DEVICE MANAGER. DOUBLE CLICK UNIVERSAL SERIAL BUS CONTROLLERS. IF ANY OF THEM ARENT WORKING PROPERLY THERE WILL BE A YELLOW TRIANGLE WITH AN EXCLAMTION POINT BESIDE THE UNFUNCTIONING USB. IF IT IS NOT FUNCTIONING YOU WILL HAVE TO UPDATE THE DRIVER. IF YOUR PORTS, DRIVERS ETC DONT SHOW THE YELLOW TRIANGLE, THEY ARE WORKING. TRY PLUGGING THE PHONE INTO A DIFFERENT PORT UNTIL YOU FIND ONE THAT WILL ACCEPT IT. I HAVE A LAPTOP AND MY PHONE ISNT RECOGNIZED IN THE SAME USB PORT (ON THE RIGHT SIDE OF THE COMPUTER) THAT I USE FOR MY PRINTER. I USE A DIFFERENT PORT FOR MY CELL PHONE. IF YOUR COMPUTER IS OLDER , THE USB PORT MAY NOT BE HIGH SPEED. OLDER COMPUTERS HAVE USB PORTS WITH A SPEED OF 1x OR A MIX OF PORTS WITH 1x AND 2.O (2.0 IS HIGHSPEED 1x IS NOT). I HOPE THIS HELPS!!!

I have just recently purchased a Samsung SHB J700, and have just installed the PC programe. I have checked that the software it up to dtae. But when trying to sync the phone to the PC, the USB connection...


after you've installed the samsung software and driver,

plug the USB cable for your phone into the BACK of your PC (or a "USB2 slot"), your computer should detect the device properly now.
the USB ports at the front often are not USB2 ports (or aren't configured properly).

this is worth a try before contacting samsung for support.

Sync Manager Problme with Vista with LG CU500


The problem is a driver issue. It is strictly a LG/Verizon problem, and not Windows. What you should is hook up your phone your computer LG USB cable and using the Music Essentials CD-ROM.

Install the latest version of BitPim where  you can find at http://www.bitpim.org/ . 
"I hooked up my phone to my computer via the USB cable, and opened BitPim. Much to my dismay, bitpim did not find the COM for the LG Modem".

However, Vista popped up the window in the taskbar telling me that new hardware was detected but could not be installed. I went to Start > Search > Device Manager
Once the Device Manager is opened up, you should see an unknown hardware profile for the USB cable/phone. In my case, Vista seemed to recognize the fact that it was a LG USB Modem, but didn't have the driver. Anyway, right click on the unknown driver and select "update driver software." Surprisingly, Vista will tell you it found a driver. Unfortunately, when when you go to install the driver 2 new unknown drivers will appear.

To fix the 2 unknown drivers, all you have to do is insert the VCAST Music Essentials disk into your disk drive, and point Windows in the direction of the files for the drivers on the VCast Music Essentials CD (in my case, the D: drive).

Windows finished the install, and from their BitPim recognized the cable on COM5.
That should work.
