No mass storage device shows up anymore, BOOTSEL included. Is it bricked or is there a recovery path?

avrdude: stk500_recv(): programmer is not responding — Uno only on this one port
Works fine on a different USB port and a different cable, but consistently fails on the one I actually want to use. Driver issue or something else?
