This is coming from a Lenovo ThinkPad X1 Yoga Gen 6. I believe this means that the USB controller is simply not identifying itself ? Does this mean we need to contact the mfg to get a firmware patch to have the USB controller(s) identify themselves correctly ?

[beadon (bryant-eadon)]

I have identified this as a RAZER Core X Chroma USB port available across the Thunderbolt 3 connection.

By disconnecting and connecting I see the mfg is set , and this is indeed on the RAZER Core X Chroma, device 8:

I suppose RAZER could tell us what's going on here... or if someone know where LPM profiles are managed, I could possible mock up a LPM profile for this device available across Thunderbolt , but this is likely not a limited case.
