Ah,ok,if you use the 2026.01 there i have this change merging the additional configs to not have a var+check for each specific case (especially for R4Lite and R4pro pcie).
Ok that was only idea i had except builtin driver/firmware. Is it a known bug (so not R4lite specific) where you get the workaround patch? On the other side you’ve said it works with same kernel on R4
