USB 2.0 - Detecting High-Speed capability

Hello,

USB 2.0 is not officially supported by any Microsoft operating system yet. But some USB 2.0 child-boards and devices are today comming on the market anyway.

Does someone have allready some experience with this new standard and can tell me how to detect high-speed capability of a device ? (Not only if the device itself is capable of such speed, but if the full chain, usb hub, intermediate device(s) and targeted device are capable of this bandwidth).

Note that I allready check USB 2.0 informations on intel website and on www.usb.org, this doesn't solve my problem, and MSDN doesn't give anymore DDK doc on line since Microsoft want to sell his book.

Thanks for any help,

David Burg.
