Hi Xiaofan, Thank you, Thank you, Thank you! I was running into dead end after dead end trying to get winusb.sys installed on my XP box.
So using both tips in your email and snippets from Peter's and Salvador's emails I finally have openocd working with the flyswatter probe and the ftdi usb driver. I'm seeing much faster speeds: At 5M with 15 tcks inserted between each scan I'm seeing 159k/sec At 15M with 30 tcks inserted I'm seeing 182K/sec Not as fast as Salvador sees but much faster than what I was seeing before. I did notice to get the probe talking to the target took a lot more resets with this driver. I took the flyswatter2.cfg from the ftdi directory and modified it for the flyswatter3.cfg and it worked so maybe we can remove the note at the top of the flyswatter2.cfg file?

You should either use libusb.git or better the fork libusbx project which provides Windows binaries. http://sourceforge.net/projects/libusbx/files/releases/1.0.14/Windows/ > Then I created a libusb-1.0 directory under the src directory and > copied the libusb.h from the downloaded source Openocd compiles but it > won't link because the libusb it looking for is libusb.a not > libusb-1.0.a > > Is there a configure option to use the libusb-1.0.a instead of libusb.a? By default it will use libusb-1.0 and not libusb-0.1 unless you use --enable-libusb0. If your libusb-1.0/libusbx files are not in the default compiler directory, you need to explicitly set the flags CFLAGS and LDFLAGS. > Also where do I find WinUSB.sys it was not built as part of > libusb-1.0.9 That is outside libusb-1.0 or libusbx. You can use Zadig to install the WinUSB driver.
