Taking a closer look at this I realised that your device is actually an HX for which bcdDevice is configurable in EEPROM/OTPROM unlike for HXD and later types. (The default HXD product string also has a "D" in it: "USB-Serial Controller D"). So we need to assume any device with bcdUSB 1.10 and unknown bcdDevice to be an HX. Johan
