Hi, the PCI ID (14e4:4315) is stored in the wireless device's serial EEPROM. If the EEPROM is corrupted, you need to find out which PCI ID it uses now. You can do that with lspci -nn. Once you found out which corrupted PCI ID your device uses, you can registe= r this new PCI ID to the b43 driver via sysfs to recognize (see PCI/sysfs document= ation). Then the driver will recognize your device again and you can flash the orig= inal serial EEPROM to the device. See b43-tools/ssb_sprom documentation [1].
