hi everybody, maybe somebody can help with the drivers I have bought a stm32f407 board, loaded i firmware, but when i tried to installing drivers, and connected micro usb it looks that drivers not is not good or something is wrong, I can lad firmware but not connect to console

Have you checked http://rusefi.com/wiki/index.php?title=Manual:Software:User/en ? It has a link to http://www.st.com/web/en/catalog/tools/PF257938

If this still does not help, them more details are needed what OS are you using, what do you see in Device Manager. Screen shots are best, http://www.softpedia.com/get/Multimedia/Graphic/Graphic-Capture/Hyperdesktop.shtml is a good tool for that

thanks for a good link but stil I not works maybe I got wrong board tried with windows7 32 bit and 64 bit

try another computer if you can. I did have issues installing serial driver on some of my laptops, took some plugging/unplugging.

just to confirm, do you have any of the four center LEDs on the board blinking or turned on?

As plan B you can get a 'usb ttl' device and connect to the firmware using that port,

when I reset the boar with te button it blinks one time red an orange led, then it blinks blue all the time

this looks right, so the firmware is in fact running.

Can you un-install those devices with warnings? It appears you have some other hardware that could be a problem. Can you remove the Broadcom USH warning?

I tried to unistall those things and tried other laptop but same thing maybe somebody know which pins I must use for conecting TTL?

Perhaps you need to install the drivers then plug in the STM. Did you happen to plug in the STM then install the drivers? The sequence may be important, but I'm mostly guessing. Did you install the drivers first or plug in the STM first?

fist I installed drivers, then only plugged in

and yes, sometimes it helps to plug the device and only install driver later. you need to just struggle long enough and it would work eventually try removing driver, installing driver, etc
