The 17aa:3820 is the Duet 7 ITL6's PCI SSID, so I don't think it's a
mistake. It is just a PCI SSID - codec SSID collision.

Here is an ITL6 probe:

There are some similar collisions with Lenovo laptops.
Please see commit 0ac32a396e4f41e88df76ce2282423188a2d2ed0 for an
example how to handle one.

Best regards,
Gergo
