USB HUB not working

SRIDHAR R over 4 years ago

Hi

I am developing a project using nuvoton m263ki development board and using keil IDE

The sample code of usb-host device connection check is not working properly

When i connect usb hub, it gets detected

When i connect flash drive into one of the usb-hub port, it is working

But When i connect keyboard into one of the usb-hub port, it is not working

Don't know why

Please give me your valuable answers

Thanks

Hi Sridhar,

It says Set address failed, perhaps you tried to assign the same address to a different device.
You should analyze your code and return error code to find out what is the reason.

Best regards, Milorad
