Description: For many embedded systems USB seems to be a good solution for data acquisitionmodules- as USB supports a frame rate of 1 ms which is fast enough for manyfeedback control applications. The problem now is that USB is currently onlysupported by Windows 98 and updates of Windows 95 . The design of the USB hostcontroller again emphasizes the possibilities using USB in an embedded System: Once the USB communication is established, the host controller can work in thebackground using DMA-memory transfers- accompanied with a synchronousinterrupt every millisecond, a real time feedback control system is easilyestablished.
