USB not recognized by Windows Device Manager

charles saperstein

got a board using a F28069. When it is connect to a host computer via USB, it is not recognized in Windows device manager on both a Win 7 64 bit and Win 8 64 bit machines. However, I was able to use the dfuprog.exe utility to update the flash.

What is wron? Shouldn't the device show up in device manager?

Can you just paste the screenshot of the device manager after inserting the board?

It came up as Stellaris Device Firmware Upgrade when I was expecting it to say TI Device Firmware Upgreade.

Hi,

I have a similar application.

I will need a schematic on the USB device. Would you have that handy?

Base on the datasheet bus power device is more easy to implement since bus power device doesn't need to monitor the VBUS signal.
