As a workaround, you should drop cardreader.conf into /usr/local/etc/devd/ (create directory if it does not exist) with contents like: attach 1000 { device-name "umass[0-9]+"; action "/usr/local/libexec/umass/attach-umass $device-name"; }; Script /usr/local/libexec/umass/attach-umass is invoked when umassX appears: #!/bin/sh PATH=/bin:/sbin:/usr/bin:/usr/sbin DEV=/dev p=`dirname $0` [ -z "$1" ] && exit 1 u="$1" # wait until dust settles i=1; while [ $i -le 10 ] do sleep 1 device=`$p/umass2da $u` if [ $? = 0 ]; then : > $DEV/${device} break fi i=$(($i+1)) done This script calls /usr/local/libexec/umass/umass2da helper to translate umassX to daY (in hope this translation is possible): #!/bin/sh PATH=/sbin:/usr/bin camcontrol devlist -v | awk -v u=$1 '\ BEGIN { s = ""; e = 1; } $3 ~ /umass-sim[0-9]+/ { s = $3; sub("-sim","",s); } /[,(]da[0-9]+.*\)$/ { if(s == u) { match($NF, /da[0-9]+/); print substr($NF, RSTART, RLENGTH); e=0; exit 0; } } END { exit e; }' Eugene Grosbein
