Firewire / PCI-E Problems / Big Sur

Successful BIG SUR - New Installation Open Core 0.6.3

Only two things do not work: Thunderbolt and Firewire PCI-E Cart.

I will be very grateful for help / Info / opportunities.

Hi,

I don't have a solution, but I'm experiencing something similar. My Firewire is recognized but the device, an audio interface, isn't visible in my sound preferences. It was working in the first few days of the install but stopped recently.

I have a post HERE with my build.
