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:</SPAN><BR /><BR /><SPAN>1. Does the N_PORTS field (fixed at 1) in the HCSPARAMS register indicate the USB controller only supports 1 down stream device. </SPAN><BR /><BR /><SPAN>2. If so is there a software workaround to support multiple device.</SPAN><BR /><BR /><SPAN>3.
