Amazing! Less than three hours after I posted you have USB working! Is that USB 2.0 and 3.0?
I presume the visionfive 2 HDMI doesn’t support audio yet does it? I’ve got some dirt cheap USB C headphone adapters (“sounds cards”) I’ll have to see if they work with haiku x86 then maybe I can use it on RV for audio? I presume the onboard audio isn’t supported yet?
