What is the VK-QF9700 Chipset? Before diving into drivers, let's clarify what you actually own. The VK-QF9700 is a single-chip USB-to-Ethernet controller manufactured by MosChip Semiconductor (originally by Davicom, later licensed and cloned). Key identifiers:
Vendor ID (VID): 0FE6 Product ID (PID): 9700 Max Speed: 100 Mbps (Fast Ethernet, not Gigabit) Bus Type: USB 2.0
Because this chip is incredibly cheap to produce, it appears in dozens of unbranded adapters. Windows 11 does not include native inbox drivers for this chipset (unlike Windows 10, which sometimes did via legacy updates). Thus, if you plug the adapter into a fresh Windows 11 machine, it will likely fail to install automatically. Here is the quickest way to get your
Does the VK-QF9700 Work Officially on Windows 11? Short answer: No official driver from MosChip or Microsoft exists specifically for Windows 11. However, the Windows 10/8.1 driver works perfectly if installed correctly. Microsoft did not intentionally block the VK-QF9700 in Windows 11, but they deprecated many legacy NDIS 5.1 drivers. The working driver for this chipset is actually a modified version of the DM9601 driver (Davicom DM9601 USB Ethernet adapter). Good news: You can force-install the compatible driver. Bad news: If you rely on Windows Update alone, it will never find it.
