I'm having the same issue with my Asus Q534UX. I reinstalled the driver, even reinstalled Windows (to fix other issues), but the Windows Hello functionality is still not working for me.

I'm getting stuck at this step. I'm not seeing the LPC on the other computer (ASUS laptop running Linux Mint). I've looked for it with lsblk to check for block devices and lsusb. Nothing shows up that wasn't there before I plugged in the Reform.

I've tried 2 USB Micro-B to USB-A Cables (in case the first one I grabbed was power only) and two different USB ports on the laptop. I've also tried switching the LPCP switch back off and on again and pressing the LPCRESET button again.

Help would be appreciated.
