I'm not sure what a "bus type" event is, but I think it's what I called a "device level" event above (one per device). Still seems to me that "interface level" events would still be good to have for USB -- handling the "multiple interfaces" case better. What I'd have called a "bus type" event is at the level of hotplugging a new bus: an adapter for USB, Firewire, IR, or what have you. Of course adapters are just specialized devices, so any distinction is arbitrary... > - class type event when a driver registers a type of device is > seen (i.e. input, tty, disk, etc.) This is the new stuff that > will allow us to move all device naming logic out of the > kernel entirely.

These "class type" events would seem to be what I've always thought of as "logical device" events. Or if you will: they're "bus type" events on synthetic busses that hold only input devices, ttys, disks, and so forth. > - bus type even when the device is removed (like today.) > > So the class events will be when a driver binds to a USB interface. > > Does that make sense? Not yet, but then I've got to read Patrick's stuff (I grabbed his docs, one webpage with HTML would be a lot more practical than so many different/unorganized text files). - Dave ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek No, I will not fix your computer. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
