You may want to use reply to all. This is not as convenient but it is the way OpenOCD mailing list is running. Thanks.

It is not working yet. It is also not API compatible with libusb 1.0. That is an unfortunate situation. > As an aside, has anyone had the opportunity to try OpenOCD with an > FT2232H-based dongle?

The blocking I/O will render the benefits of high speed USB much less effective. David Brownell is the real USB expert in the list. He may answer better, at least on the Linux side since he is one of the leading Linux usb developers. -- Xiaofan http://mcuee.blogspot.com _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
