As of 2025-2026, CoreChip has been slowly pivoting toward USB 3.0 to Gigabit Ethernet chips (e.g., SR99xx series). However, the majority of devices in circulation still use the legacy USB 2.0 SR9900.
Apple is notorious for breaking third-party Ethernet drivers with every major update (e.g., Catalina, Big Sur, Monterey, Ventura, Sonoma). While some CoreChip chips use Apple's native CDC Ethernet class, many require a specific .pkg installer. If you see "Not Configured" in Network Preferences, you need the driver.
It looks like you’re searching for the driver for a Corechip Semiconductor USB to Ethernet adapter (often labeled with the model ). These are very common in budget USB-to-LAN dongles.
