I had same problem had to send it back for warranty. Be warned shipping cost is on your dime, they will only reimburse a small amount and what they do reimburse is store credit only. I was not informed of that when I sent mine in
What is the repair they do on your motherboard?
I think they replaced the USB port but I’m not 100% sure

have a nice day,
Does this material affect the USB 2.0's on the device not working?
What is the purpose of using this material?

It is a high-side MOSFET switch (I am guessing) to turn ON/OFF the USB port's DC power.
BTW, if ONLY that MOSFET is defective and everything else is okay, then the USB port will still work, if the USB peripheral device(s) is connected to a POWERED USB Hub, while that hub's upstream port is connecting to that (affected) USB port on the LattePanda side.
