Just unpacked my Eachine Wizard X220S and followed the setup procedures to the letter. The motors were unresponsive to unlock and arming so I tried to connect to Betaflight to see what switches were suppose to be on (I set SWB to Channel 5).

When I connected the quad to the micro-USB the Betaflight app was unresponsive (Serial Port Open then Serial Port closed) and my computer did not recognize it at all..no beep..no nothing. I downloaded Zadig, the STM32 drivers and tried again and still nothing when I plugged into the FC. I took the FC out of the brick stack and held down the bootloader button while I connected the micro-USB and still nothing.

I have watched so many videos and tried many different things but I can not get the FC to recognize as a USB device. I tried on a WIN7 machine and a WIN10 machine and tried several different USB ports and cables. At this point I think I got a DOA FC in my quad.

Am I missing something here?

Have you restarted the PC for the drivers to take effect? That was my problem!

Several times. I even uninstalled the USB drivers that were there and restarted.

Try the ImpulseRC Driver Fixer

I believe the wizard uses spf3. You just need the cp210x driver.

hi Eageleye, welcome to IntoFPV.

I had a similar problem with a FC, but eventually realized I was flashing the wrong firmware. Ultimately though I was still able to get it to connect in DFU mode.

Do you happen to have any other quads or FCs around that you can connect to your computer? If you do, do they connect just fine? If they do then it might just be the board, especially if it's not connecting in DFU mode.
