Yes I cannot reproduce with your script or with the script i use; though.
However I do recall before in openbsd if your model has the 'usb features
setting' for 'automatic or MSC, perhaps try changing from auto to MSC or
vice versa whatever your setting may be, autodetect on mine never worked
very well not just on OpenBSD, Issues arises in W2K3/XP as well.
Here's the attach/detach script i use.
#!/bin/sh
DEVCLASS=$1
DEVNAME=$2
MOUNTDIR=/mnt
XUSER=`ps -axwwo user,command|grep Xsession|grep -v grep|tail -n1|cut -f1 -d" "`
function mountdisk
{
I=0
for l in `disklabel ${DEVNAME}|sed -e "s/^ *//"|cut -f1 -d" "`; do
if [ ${I} -ne 2 ]; then
# ignore the two first lines of disklabel
if [ "$l" = "#" ]; then
I=${I}+1
fi
else
PART=`echo $l|sed -e "s/://"`
if [ ${PART} != "c" ]; then
DIR=${MOUNTDIR}/${DEVNAME}${PART}
if [ ! -d "${DIR}" ]; then
mkdir -p ${DIR}
elif [ -n "`mount|grep ${DIR}`" ]; then
umount ${DIR}
fi
if [ -n "${XUSER}" ]; then
chown ${XUSER} ${DIR}
chmod 700 ${DIR}
else
chown root ${DIR}
chmod 755 ${DIR}
fi
mount -o nodev,nosuid /dev/${DEVNAME}${PART}
${DIR}
if [ $? -ne 0 ]; then
rmdir ${DIR}
fi
fi
fi
done
}
case $DEVCLASS in
2)
# disk devices
mountdisk $DEVNAME
;;
esac
#detach
#!/bin/sh
DEVCLASS=$1
DEVNAME=$2
case $DEVCLASS in
2)
# disk devices
rmdir /mnt/${DEVNAME}*

Doubt this may be of any use the only sysctl knobs i have adjusted are
net.inet.tcp.ecn=1 # 1=Enable the TCP ECN extension
ddb.console=1 # 1=Permit entry of ddb from the console
kern.usercrypto=0 # 0=Disable userland use of /dev/crypto
kern.splassert=2 # 2=Enable with verbose error messages
kern.emul.linux=1 # enable running Linux binaries
kern.bufcachepercent=80
Apologies for the noise, Feel free to contact me off list if there's
anything else I can help with, Unfortunately I do not have te m250 model.
I will read up on the diff between yours and mine, sometime this afternoon,
evening when time permits.
Note: the attach/detach hotplug was not written by me.
Cheers
