Firmware version with driver

I was wondering if someone could help me make sure that the firmware version is up to date LimeSDR-USB FW:4 HW:4 Protocol:1 GW:2.21 Ref Clk: 30.72 MHz
Limesdr-usb driver installation complete, management list displayed correctlyimage

Depends what version of Lime Suite you have installed, as the firmware/gateware version corresponds to this. Obviously the best strategy is to have the latest version of Lime Suite installed.

My Lime Suite is the latest version I downloaded online

If you run LimeUtil --update it should update the board if this is needed.
