We went over that path already. Nobody's advocating that Linux change, to reserve at that time, certainly not me. > For example a webcam driver would want to claim a webcam's interfaces on > device connection, but it shouldn't reserve ep bandwidth until a user > application is ready to use the device.

The only thing with those semantics is a call to write() or read(). ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
