+libftdi can be built to work under win32 (cygwin/mingw) after applying the patch in this directory.
+
+The issue is caused by windows requiring usb_set_configuration to be called before the usb_claim_interface.

-Please note that the ftdi2232 variant (using libftdi) isn't supported under Cygwin.
-You have to use the ftd2xx variant (using FTDI's D2XX) on Cygwin.
+libftdi is supported under windows. Versions earlier than 0.13 will require patching.
+see contrib/libftdi for more details.
In general, the D2XX driver provides superior performance (several times as fast),
but has the draw-back of being binary-only - though that isn't that bad, as it isn't
