Greetings @Affiinity.

Sorry to read that your fifine USB microphone is not working with the USB port.

Here are some other troubleshooting steps I think may perform and then see how it goes.

Perform a static discharge/power cycle
- Remove all cables connected to the device (power cable, hdmi, external mouse, external keyboard, etc)
- Be sure device is switched off / powered off
- Press and hold down the power button for 60 seconds
- When done, re-attach all cables
- Attach the  ac adapter and let the unit charge for about couple of minutes

BIOS Load Default Settings
- Press the Novo Button: https://support.lenovo.com/ph/en/solutions/ht062552-introduction-to-novo-button-ideapad
- The button can be reached/clicked by an unfolded paperclip or similar. The machine will power up to BIOS.
- Choose the BIOS setup.
- If you do not have a Novo Button, then repeatedly pressing F1 of F2 or Shift + Power button (FN+F1 or F2) on startup will take you to the BIOS.
- Inside the BIOS Set Up, navigate to the Exit Menu.
- Select Load Setup Default - click Enter, select YES and click Enter.
- Select Exit and Save Changes then click Enter, select YES and click Enter.
- Laptop should boot back to Windows.
- Check if the USB's are now working, if no, then continue below:

System Board/Motherboard Update
Download and Install the newest BIOS, Chipset drivers for your device:  
You can find and install the newest drivers from the Lenovo Support Page: https://pcsupport.lenovo.com/ 
 
Just plot in the serial number of the device and hit enter, might have to press it twice, then head to Drivers & Software, select Manual Update, then select the BIOS and Chipset section
**Note: Make sure the AC adapter is connected and that you have at least 30% battery charge when performing system board updates.

Re-install USB Root Hub and Host Controller
Try right clicking the USB Root Hub and/or the Host Controller, select disable, then re-enable it. If unsuccessful, right click and uninstall both + drivers, then restart the device and have Windows install the generic drivers for the devices.

Try testing the specified USB mic to the affected USB ports.
