Relevant line in output of 'usbconfig show_ifdrv' command is ugen1.3: <Microchip Inc PolarFireSoc-FlashDrive> at usbus1, cfg=255 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA) which does not tell much, I think. Anything else I can try to get something meaningfull? Note, my FreeBSD box is rather old, 11.4-STABLE, test done on 12.2-STABLE was basically the same. Regards, Milan
