TM4C123GH6PM: TM4C123GH6PM USB

Part Number: TM4C123GH6PM

Hi.

I 'm studying Lab 7 in "Getting Started With the Tiva C Series TM4C123G LaunchPad Workshop" .
I have a problem with USB Device. My computer didn't recognize the LaunchPad. I have tried to install the driver in C:\ti\TivaWare_C_Series-2.1.2.111\windows_drivers but it can't installed.

I have seen this tutorial on Youtube and follow but it didn't work.

What should I do to make sure that my LaunchPad work ?

    Yet - a day or two earlier your computer "recognized your LPad" - did it not?     (i.e. you questioned the operation of the GPIO interrupt - confined to a few pins.)

    Is it correct to assume that your (previously working) LPad - no longer performs?      As you have progressed to Lab 7 - such would seem the case - does it not?

    Are you stating that you are "Locked Out" from your LPad - or are you noting that your computer cannot "see" the LPad via the "Device Port?"    (at least to me - such is unclear...)

    You were not very clear as to which step you are having problems with. When you connect the USB cable to the debug port (USB #1 in the picture) were you able to compiler and load the "usb_dev_bulk" project? You should then see the "Stellaris In-Circuit Debug Interface" in your device manager. Execute this code, then add the second USB cable to the device port (USB #2 in the picture). You should then see the "TivaWare Bulk Device" in the device manager. Note that I used the latest version of TivaWare, version 2.1.4.178 and I am running on a Windows 7 machine.
