Board shows up as unrecognized

Pretty much what the title says. My board used to show up in windows as a webFPGA device, but after sitting alone in a drawer for a few months it’s now showing up as unrecognized in Windows, and doesn’t work in Linux either anymore. Is there a way we can flash the firmware onto the USB chip to get the device to show up as a proper USB chip again? Is this a thing that happens normally?
