Some of the newer devices have multiple logical "interfaces" (read this in a loose sense, not meant to equal USB interfaces). Somethimes the device offers all the interfaces at once, sometimes you can choose one or the other. USB example - speakers. There is an audio interface (usually with some selection of sampling rates, which you might consider to be a choose 1 of N interfaces) and a HID interface (for button controlling volume, etc). We need some way of selecting the interfaces we want, and associating them into sensible groups (so that if I have two speakers, and a multimedia keyboard; I can get the volume controls on each set of speakers to only control those speakers, and the volume control keys on my keyboard to control the built-in (PCI bus) soundcard. This is really a policy thing, and the kernel is probably provding enough when we have topology, but there is a lot of userspace work to be done. > - driverfs and the input layer must be documented I'm working on the input layer docs now. Greg: do you know of any plans to document how userspace should use driverfs? Thanks for writing this up Oliver. Brad - -- http://conf.linux.org.au. 22-25Jan2003. Perth, Australia.
