Problems caused by use of a USB hub.

Software application not set up to receive MIDI data from Photon controller.

Software application not receiving MIDI data.

Photon's MIDI channel not the same as application's incoming MIDI channel.

Sound source's notes out of range of Photon's keyboard.

Try unplugging the Photon from any USB hubs and connecting directly to the computer.

Ensure that the Photon or "USB" MIDI device is listed as an active MIDI source in your application.

Many software applications have MIDI IN and OUT indicator lights. Play some keys and look for the MIDI IN light to indicate activity.

Be sure that the Photon is sending MIDI data on the channel that the target device expects.

Try using a piano sound as you're first getting connected. Drums and basses and some other instruments may have a limited MIDI note range or other idiosyncracies. Use "easier" instruments like pianos when you're setting up the Photon for the first time.
