Yes, Linux-USB thinks that the endpoint is invalid. It prints that the endpoint's maxpacket (size) is 0. I've only seen this happen when the incorrect USB configuration or USB interface was selected on the device. I.e., trying to use endpoint N for an alternate config, which was not active. In my case the code was correct and the interface that I was trying to use had not been selected (made active). (This was for an Intel webcam with lots of alternate interfaces.) -- ~Randy ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
