Where do you get the libusb0.dll file? You should use the latest released DLL 0.1.12.2 from libusb-win32 page. The previous version may 0.1.12.1 may have problem with USB composite device. But I am not sure about arm-jtag-ew. I do not think libusb0.dll is the problem. It is said that arm-jtag-ew emulates the J-Link in low level API. It takes quite some for OpenOCD to get J-Link working properly. So I will think the first support is probably done by reverse-engineering and there may be something missing in the process. There are different firmware version for the J-link. They even use different endpoints and supported command set are not always the same. Maybe this is the case for Olimex Arm-Jtag-EW as well. In that case, even if the original support is good, it may not be good for yours. The first thing to check is the USB Descriptors. You can post yours. Probably the original author of the patch can compare yours with his. Under Windows, you can use usbview to post the USB descriptors. http://www.ftdichip.com/Resources/Utilities.htm -- Xiaofan http://mcuee.blogspot.com _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
