OK, but you probably could have made a HID touchscreen work by just using the existing HID driver and the input subsystem (with mouse output, event device output or even the touchscreen output - see the http://linuxconsole.sf.net CVS archive), depending on what your userspace application for that touchscreen data needs to see. As for sending HID data over bulk endpoint - you can't. See HID specification 1.11, Section 4.4. How about providing the descriptors for this device? (eg /proc/bus/usb/devices and maybe a HID dump). I think that you should probably go back to the developer of your device, and get all the required programming information. Maybe reading some of the docs linked off http://linux-usb.org (such as the programmers guide) and http://www.usb.org/developers (such as the USB spec) would help too. Then, if you could explain what your device actually does, we might be able to provide reasonable answeres. Brad _______________________________________________________________ Have big pipes?
