For A&H ZED-R16 on M3, Sonoma 14.7.6, it's not flying. the kext is not loading on boot (or device connect, or whatever), have to manually load w. kmutil. The device shows up in FW device tree (after power-cycling when connected) but nothing in AMS. Kext seems to somehow unload after a while (disappears from kmutil showloaded list). It always shows up w. 0 address. Also tried w. Motu Ultralite FW – it happily starts on bus power but does not show up anywhere (Warning: Unable to list FireWire devices). Any ideas? Thanks.
