Setting the configuration determines what the interfaces are, so if you do SetConfiguration, you must do that before claiming the interface. There is no such thing as an "alternate configuration". Claiming the interface will set alternate setting #0, so you only need to set the alternate setting number if you have more than one, and you will (almost) never have more than one unless you have isochronous pipes. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ------------------------------------------------------------------------------ The Go Parallel Website, sponsored by Intel - in partnership with Geeknet, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials, tech docs, whitepapers, evaluation guides, and opinion stories.
