I do not use perl. But I think the above is not that difficult for the programmers here. It is not that necessary though. The INF file generated by libusb-win32 is very easy to understand and the modification is not that bad even with Notepad. ;-) > (d) If the above is simple - and I believe it is - then "packagers" of > OpenOCD *could* - then package "LibUSB0.sys" with the INF file.. and the > more general problem would be solved. The libusb0.dll file is also necessary.

In that case, I used the command line installation method. But Gene Smith mentioned that it may not survive the reboot. I had not such problem under XP and Vista 32bit. -- Xiaofan http://mcuee.blogspot.com _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
