I am only claiming the interface I need. Barry only ever needs interface class 255, for Database access. Martin was saying on irc that perhaps I don't need to call set_configuration() at all, since config 1 is usually selected by default, and setting it again is like pulling the rug out from under usb_storage. (and therefore I get the Device Busy error) I'm trying to determine if there is a way to read the current config through libusb, in order to avoid calling set_configuration() if it is already using #1. > I might not be understanding the situation correctly, I haven't looked > at any USB related code yet and I'm only somewhat familiar with these > concepts so far, so I apologize if the above paragraph is useless. No worries. Many eyes make all bugs shallow, as they say. :-) - Chris ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
