Hi, I need to control device ( pendulum ) using USB, transmiting data not slower than 1ms. Target platform is x86 with RTOS, probably WindowsCE . One of possibility is to use FTDI chip but they probably do not provide 'real-time stack' drivers. I have heard that in USB2.0 EHCI it is possible to send data with 125micro seconds, how to achieve that?
