Note that here, an indicator is given that a driver is in use. If not, then no driver has claimed responsibility over this hardware. Assuming the driver was built as a module rather than built-in, try modprobe  to attempt loading the right module. If the driver was built-in, consider making it a module, because modules can be loaded with modprobe and unloaded with modprobe -r which saves on number reboots while debugging the issue.
