I recently scavenged a new USB-to-LAN adapter manufactured by Apple Inc. The model of the adapter is A1277. After I plugged it into my Windows PC, the device was recognized correctly in the device mgr but Windows is not able to automatically install the driver for it.AnalysisThe A1277 has the hardware ID VID05AC/PID1402 which indicates it is one of the Apple devices however Apple didn’t provide a Windows driver for it. The A1277 uses the AX88772A IC manufactured by ASIX. This IC provides the cross-platform driver.
