Hi, > I ported my test program to D2XX and it behaves identically, so it doesn't > seem to be a bug in libftdi.
It seems I had done the port from an old version with a bug - when using d2xx the factor is always about 0.25 - for sync and async bitbang. This most probably comes from d2xx reading it's data in a background thread instead of synchronous in one thread. So I have created a version of baud_test with substantially reduced usb read timeout and this yields the same results. So one question remains: why is bitbang always only using 1/4 of the expected baudrate? Kind regards, Gerd -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
