TM4C1294NCPDT: Cannot install proper USB driver for Tiva C connected Launchpad hardware USB (CDC example) on Windows 10

Hi,

  I found this thread with similar question as yours. Can you try it and see if it works.

Hi Charles,

Thanks for the thread, unfortunately updating the ICDI drivers with the ones listed in the thread didn't resolve the issue.

To be exact I'm not looking for the ICDI drivers for the TM4C1294, actually they work just fine, the actual USB CDC (CSerial example) driver isn't working.

Another note, the TM4C1294 doesn't have a "power switch" like the TM4C123G to switch USB power from the debug port to the built-in one (I used this feature back in the days with the Stellaris LM4F120 LP).

Thanks,

Karim

Hi,

  After you downloaded the patch and make the Windows pointing to the new driver folder, can you do a restart on your PC? Will that make a difference?

Nothing even after restarting the PC.

Cheers,

Karim

Hello Karim,

You are using usb_dev_cserial right? There is an issue with enumeration for that which we have resolved but it is not in TivaWare (yet, but will be later this month!).

Do you need a single port CDC example or do you need the composite version?

If you only need a single port example I can just provide that.

Hi Ralph,

Yup, I'm using the usb_dev_cserial example. Thanks for the the update on the driver issue, I was pulling my hair wondering what is wrong with the PC.

That would be great if you can provide me with single port CDC example, that would be really much appreciated. The composite version isn't really useful for the application I'm building.

Thanks,

Karim

Thanks Ralph, much appreciated.
