FileNotFoundError when using eGPU

[shade-belisar]

I'm running Linux Mint 21.3 on a GPD Win MAX 2 (2024) with a RX 7900 XT attached via Oculink. In this constellation the hdd daemon does not start, instead it throws this error:

This only happens when the eGPU is attached, without it there is no issue. Is this a bug in hhd, or would I need to configure something for this case?

Linked issue: #15

I fixed the crash, but APU detection is still spotty. I will push a release later today.
