Is the device fused to reject standard qcs6490 firmware? If not, can we
point it to the existing files (maybe except the ADSP)? Anyway, could
you please submit the required set of files to the linux-firmware repo?

As Konrad has asked, please describe the onboard hub and the USB ports.
This will ensure that corresponding ports are correctly marked as
hotplug in sysfs.

No, the device is not fused. So it can use firmware from linux-firmware
repo, except ADSP and Audioreach topology.
Sure, I can submit the ADSP firmware and Audioreach topology file to
linux-firmware.> >> +

Yes, please. Also please consider adding ADSP fastrpc shell and modules
