EK-TM4C1294XL: Why USB is not detecting while running example code "usb_dev_cserial"?

Omkar Dixit

I was trying to run the "usb_dev_cserial" example using CCS. After building successfully i flashed the code. Finally I connected the usb cable to the board but when i checked the connection i found that windows (windows 7) hasent detected.

Also I tried to install the windows drivers "C:\ti\tivaware_c_series_2_1_4_178\windows_drivers" but still its not working?

Is I'm missing something?. Any help will be really appreciated!

Hello Omkar,

Are you sure you are having an issue with Windows 7 and not Windows 10?

In any case, I would suggest you use either the drivers from 2.2.0.295 or our patch drivers for 2.1.4: http://software-dl.ti.com/tiva-c/SW-TM4C/latest/exports/SW-TM4C-2.1.4.178.PATCH-1.0.zip

In Windows 10 the composite example had an issue that required further changes. But with the attached patch driver it should run in Windows 7. If you are using Windows 10, please use TivaWare 2.2.0.295 for the version that has been bug fixed.
