Subject: [usb] a question about high speed usb enumeration

Hi,

 

In full speed USB system(win2k or winxp),  I record some enumeration sequences from host like

    reset

    get device descriptor(40 bytes)

    reset

    set address

    get device descriptor(12 bytes)

    get configuration descriptor (9 bytes)

    get configuration descriptor (full length)

    get string descriptor

    set configuration

    set interface

 

My question is, what is the enumeration sequence when a high speed device is pluged in a high

speed host(win2k or winxp)?

 

Thanks.

 

Zhuxl
