Please run "xusb -d 1cbe:00fd" and post the output. Thanks. Take note the interface sequence is fixed by the USB device and will not be changed by OS enumeration. So Windows 7 and Windows 8.1 should not really matter. It seems to me this is related how you install the driver. Are you using WinUSB driver? How do you install the WinUSB driver? Are you using Zadig to install the WinUSB for the relevant interface? Apparent Interface 0 and Interface 1 are for the virtual serial port. And Interface 3 is the DFU interface. So Interface 2 is the only interface you are interested. Try to install WinUSB driver only for Interface 2 to see if that helps. If that does not work, then you may have to use WinUSB driver on the whole device (you will lost the serial port and DFU function) and see if that works. -- Xiaofan ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ OpenOCD-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/openocd-devel
