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

USB HUB is currently not supported.
But in my sample code, i am having so many functions for hubs and they are used and my hub is also working
but when i connect keyboard into usb hub it is not working
I am attaching my error details with my devices for your reference
Hi Sridhar,
I didn't know you are actually implementing HUB handling code with vendor provided USB implementation.
You should start by understanding why you get TD Error, it seems like TD means Transfer Descriptor.

Thanks for your reply
I am getting that TD error and i don't know how to avoid it
Do you have any idea why i am getting that error?
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.
