I am using the LPC4337 in a USB application that needs to connect via USB0 (host) port to 4 downstream devices. My board has a Cypress CY7C65632 hub controller connected to USB0. I have used LPCopen examples for a single device connected to USB1 - works fine. questions:

1. Does the N_PORTS field (fixed a 1) in the HCSPARAMS register indicate the USB controller only supports 1 down stream device.

2. If so is there a software workaround to support multiple device.

3. Can anybody recommend another library or application note that would show how to support multiple devices

Thanks
