why you want to check the firmware of the UMCP2? Currently there is no new firmware for this device. So you don't need to update this firmware. But if you want to see which firmware your UMCP2 has you should see the firmware version at the Audio control panel of the driver or at the device information of the UMCP2 at the hardware manager of your operation system.

Hello Christain, it's just the curiosity of a technician . I thought it was possible to see the firmware by press a combination of keys. Thanks for your reaction.
