Is it possible for OSDK 4.x to connect to the drone only via USB or only via serial?

Keywords: OSDK USB communication, serial communication

No,

OSDK must use a serial port to communicate with the UAV, so a serial port connection is necessary.

In addition, the OSDK 4.x version will use USB communication for many functions. It is necessary to connect the USB and serial cable at the same time and ensure that the communication is normal.

If you don't connect USB, the related functions of USB communication will not work,

such as: waypoint v2, advanced sensing, gimbal manager, camera manager, MOP etc.
