Trouble connecting to update firmware. Ihave found that when I connect my board to my computer I only see Usb serial device (com 4) under Ports in Device Manager.  I do not gain a USB composite device, Under USB header, when I connect or lose one when I disconnect and am completely unable to update firmware or use board. One weird thing is that if I go in and set to COM 4 and select connect in LibrePilot (lower right corner of screen) it almost seems like it does connect, Tx goes to 24, but I am still unable to do anything with it.

Hi,

You do not need to use the serial port, except if you configured the VCP as Telemetry.

Try a Manual update:
- Disconnect board
- Firmware tab, click "Upgrade&Erase"
- Connect board
