The USB spec is only a data carrier, it doesn't define any protocol for actually doing anything. All that is left up to each device manufacturer. So you need to find your device's specification or reverse engineer it if you want to make it do anything.
Also, as far as listing the "contents of a device", I am highly doubtful that any device would bother providing that since it doesn't seem very useful. But again, it's entirely up to your device manufacturer. On 7/13/07, Crashy Ice <[EMAIL PROTECTED]> wrote: > Thanks Dan, i was a little confused. > > I have another question.
