MSP430F5529: MSP430F5529LP: "C0_SimpleSend" example: "device driver software was not successfully installed"

Part Number: MSP430F5529
Other Parts Discussed in Thread: MSP-EXP430F5529LP

Greetings,

I have an MSP-EXP430F5529LP board.

I've used "Import to CCS Cloud" to import "<TI Resource Explorer>\Software\MSPWare\Development Tools\MSP-EXP430F5529LP\Middleware\USB Developer's Package\Example Projects\CDC (Virtual COM Port) Examples"\C0_SimpleSend".

The project appears to compile successfully.

I think the project "Run"s correctly - it stops by itself after several dialog/popups.

After Running, there is a new device named "MSP430-USB Example", under Device manager\"Other devices".  The device-icon has an exclamation-mark and Windows displays the message "Device Driver Software was not successfully installed".

I think this example has worked at home under Windows 10.  The problem is occurring under Windows 7/64bit.

Is there an INF file that I should examine for correctness?

Any help is appreciated.

Follow-up: After hunting for inf files I found/installed "C:\ti\MSP430USBDevelopersPackage_5_10_00_17\MSP430USBDevelopersPackage_5_10_00_17\MSP430_USB_Software\MSP430_USB_API\examples\CDC_virtualCOMport\C0_SimpleSend\USB_config\msp430_ti_signed.inf"

... and now see a healthy "TI MSP430 USB" device under "Ports (COM & LPT)" (which my app is having trouble Opening...)

Follow-up: READING TIMESTAMPS!!!

... I'm not sure what changed, but it appears my app reliably opens and reads the COM port.

NOTE the following comments from the example's Main.c

"

* Simply build, run, and attach to a USB host. Run a terminal application

* and open the COM port associated with this device. (In Windows, check the

* Device Manager.) The time should be displayed, every second.

    Can I gather from your follow-ups that you've solved the problem or do you still require assistance?

    Hi Ryan,
    Do you have any suggestion as to why the example didn't work as expected?
    Was it "correct" for me to install "C:\ti\MSP430USBDevelopersPackage_5_10_00_17\MSP430USBDevelopersPackage_5_10_00_17\MSP430_USB_Software\MSP430_USB_API\examples\CDC_virtualCOMport\C0_SimpleSend\USB_config\msp430_ti_signed.inf"?

    To the extent that the example seems to be working, you could say "the problem" is solved.

    Hi B Lench.
    The example worded as expected. The first time a CDC example with the VID/PID of 0x2047/0x300 is downloaded to your device connected to you computer the Windows 7 OS expects to see a INF file. This is Windows 7 and 8 requirements. In Windows 10, the CDC is automatically recognized however it shows up as a 'Generic Serial Device', I believe. If you want it to show up as 'TI MSP430 USB (COMxxx)' then you will have to point it to the .inf file for installation. Anyway, unfortunately right now there is not a way of telling your Windows 7 or Windows 8 computer to grab the .inf file from the cloud project to install it on your computer.

    If you have the MSP430USBDevelopersPackage_5_10_00_17 installed in your C:/ti folder, there is a Programmers Guide and Examples Guide documents that explain how the examples work and what is required to run them.

    Hi Arthi,
    Thanks - I guess it's not as simple as the program-comments implied.
    Looks like it's time to "Read The Manual". ;-)
    Cheers,
    Bill
