Please, if you're going to post to the lists at least take the time to read any responses before repeat posting. I refer you to my previous post here... http://ecos.sourceware.org/ml/ecos-devel/2009-06/msg00001.html > I got output on hyper terminal and program run on stm32 evel board like > this, > STM32 USB : Setting USB device address = 1 The fact that Windows is recognizing the device and asking for a driver, and a valid USB device address is being assigned means that the STM32 driver is basically working. If you must use Windows as your USB host, you'll now need to put together a USB class driver for a standard device type which it will recognize. You could try a simple HID, for example. Chris.
