[quoted lines by saeid javani on 2016/07/20 at 12:11 +0430] >I have a usb-cdc device and want to write a driver for it. Using libusb-1.0
Is it a braille device? If so, is it one that we already might suport? >in a simple program I can communicate with this device. But in brltty, it >can not claim interface. Actually early control communications are fine and >brltty receives device model and number of cells from device but after >that, claim interface error occurs. Are you doing this on Windows or on Linux? > .configuration=0, .interface=1, .alternative=0, I strongly suspect that the configuration number should be 1. > .inputEndpoint=0x83, .outputEndpoint=0x04, As Mario has already observed, the input endpoint should be being specified as 0X03. Note: If you're doing this on Windows (which is what I suspect since you're using libusb-1.0), you could just tell brltty to use serial:COM1 (or whatever), and use the serial device that Windows has allocated for the CDC ACM device. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
