I have a problem with installing driver in subject. In reality it is a problem with installing usbser.sys driver. I install many time Librepilot and aparently this program should
install right driver. But it wasn't.  All time I have in right lower corner of program information that com1 is disponible to connect and program don't work. Zadig gave any result. Still I have Com1.
Finally, I have found in Device Manager many CopterControl and in different place. I removed all instance of this CopterControl and after that LibrePilot start working correctly,.

Any question, I will help.  Thanks,

Librepilot can use the com port if FC usb port is configured as VCP.
In most cases you do not need the com driver to be installed and board uses HID by default. (see preferences)
