Any other information that may be helpful

only ever seen the coral listed under lsusb as: Bus 003 Device 006: ID 1a6e:089a Global Unichip Corp. Could it be faulty?

I’m also struggling with HW Accel although my gpu won’t be up to much intel hd 6000. both of these symptoms seem to be mentioned in reference to a protection mode which needs to be turned off but I’m unsure if this is relevant if not installed on hassos.

I don’t really know linux but i’ve read and tried most of the advice mentioned in reference to issues similar to this. cheers
