That workaround is OK. But can you actually mount the USB CF reader? Mine shows up as da2 umass0: SanDisk Corporation ImageMate CompactFlash USB, rev 1.10/0.09, addr 5 umass0: Get Max Lun not supported (STALLED) da2 at umass-sim0 bus 0 target 0 lun 0 da2: <SanDisk ImageMate II 1.30> Removable Direct Access SCSI-2 device da2: 1.000MB/s transfers da2: 1027MB (2104705 512 byte sectors: 0H 0S/T 0C) but there's only /dev/da2 under /dev, and no entries for the slices. Shouldn't devfs or usbd or something create them automatically, since MAKEDEV is no more?
