OK; is it one of the ones listed at the end of usbdevice_fs.h ? I don't see an obvious one... I would be happier if I could prevent it from ever getting bound in the first place though! >> Choosing configurations: It looks as if I get two uevents when a device >> is attached, one for the unconfigured device and another once the core >> has done SetConfiguration.

Nothing at all, except that the device will have been given first one configuration and then another in quick succession. I don't know if that would ever be a problem. >> it had chosen.
