how do you know if it's damaged? there's green light but it doesn't work anymore?
and how do you fix it?
You need to provide a bit more information. What usb hub is it running on and have you tested the hub seperately? What voltage is the core? What freq was it running at? Has windows done any updates and changed the driver back again so may need to do zadig again? Any pictures of the back of the pcb to see any physical damage?
