PTT (with foot switch) not working on a 6500

Options
I use the FLEX 6500 with a USB microphone. When I press the MOX or VOX button, the transceiver switches to transmit mode, and everything works fine. However, when I press the foot switch, the transceiver switches to TX mode, but there is no actual transmission. I've tried doing a RESET and even upgraded SMARTSDR to 3.4.24, but it didn't help. Can you suggest what I can do to fix this issue?

    This is working as designed.

    When you use a Foot switch plugged into the back of the radio, the Mic must be connected to the radio.
