To resolve issues with , you should use official manufacturer sources:

The most common cause in the wild is hardware spoofing or device emulation . Someone creates a piece of hardware (for research or, less legitimately, for cheating) that impersonates a real device. To make the OS accept it, a custom driver is created that tells the OS, "This device is exactly an Intel SMBus controller" [10†L15-L18]. A telltale sign of such a driver is a log entry marking it as PATCHED [4†L13-L14]. This technique is documented in cybersecurity research on PCIe attacks, where an attacker's device can "mirror the identity of a real, legitimate piece of hardware" to operate under the radar [10†L15-L18].
