You can find the description of some of those ports in usb1_core.v between lines 96-108 (these are comments). For further explaination of wIndex and wValue, you can look at section 9.3 of the USB 2.0 spec. These two ports have different meanings for different device requests. You will find details in the spec. Rahul ----- Original Message ----- From: M. AbuKhaterperocletos@y...> To: Date: Tue Apr 27 15:32:45 CEST 2004 Subject: [usb] USB1.1 Core
