I have a P3advanced with no camera used for other things. Is it possible to update the firmware via the usb port as the machine has no sd card reader?

Why do you need to update? And my guess is no it won't be possible but i could be wrong. If you still have the gimbal you could reattach and update normally.

If you put it this way - discussing possibilities - then yes, it is possible.

The camera updates firmware in all other modules by sending DUML commands to them:
- enter bootloader mode
- start firmware binary transfer
- send binary firmware chunk (repeated until whole firmware is sent)
- confirm uploaded firmware validity
- store the new firmware
- reboot

So - all you need to do is to capture the communication between modules, learn details about the protocol and write your own firmware updater which would send the DUML commands via virtual serial port which you get after connecting the USB cable.

Or you can reverse-engineer camera firmware and get the detailed update procedure from there.

Completely possible.
