My guess is that the fob is marginal and takes a while to stabilize after being plugged in. GEOM first tastes it when it is plugged in, it is still funky, and GEOM fails to read the partition table. Then you try to mount /dev/da0, it is opened r/w, which causes GEOM to retaste it once it is closed; by that time, it has settled and the second tasting succeeds.

Also, trying to mount /dev/da0 does produce the MBR entry in the GEOM config: 1 MBR da0s1 255849984 512 i 0 o 2048 ty 11 It also produces a single "READ CAPACITY" CAM error like those produced when the device attaches. I also tested with a known-good USB zip drive plugged into the same USB port. It attached flawlessly: the console showed the normal attach messages, GEOM config shows the appropriate MBR entry and /dev/da0s4 is created. So yeah I gueuss my fob is busted or funky.

Attached as named above. The logs show the da0 DISK class in the GEOM
config, but no MBR class entry.

Yes, it does. When the umassX provider shows up, GEOM immediately
tastes it and creates geoms for the individual slices.
If it really doesn't on your system, try the following:
# /etc/rc.d/devd stop
# logger START
# sysctl debug.bootverbose=1
# sysctl -b kern.geom.conftxt >geom-before
[insert umass device, wait 10 secs]
# sysctl -b kern.geom.conftxt >geom-after
# sysctl debug.bootverbose=0
# logger STOP
# /etc/rc.d/devd start
# awk '/START/{s=1}{if(s)print}/STOP/{s=0}' /var/log/messages >geom-logs
then post the contents of geom-{before,after,logs}.

One could kludge it to send out geom events, but I think that's insufficiently general since it reports too many things that aren't of interest. Of course, you have no way of knowing what entries in /dev really are, apart from pattern matching. As to your second question, GEOM and/or da (it depends on who you ask) need to react to certain events and re-taste the device. This isn't done automatically, especially when da0 changes from a 32MB to a 64MB part, for reasons I've never known.

Determining disk device and kicking GEOM when doing automatic mounting of umass devices
I want to have a devd entry that automatically mounts umass devices when
they get attached. The problem is figuring out which device to mount and
then getting the correct devices created. For example, the entry for my
thumbdrive:
attach 1000 {
device-name "umass[0-9]+";
match "vendor" "0x08ec";
match "product" "0x0015";
match "sernum" "0C50935151F0EA20";
action "$scripts/mount_umass.sh $device-name msdosfs /stickdrive";
};
The mount_umass.sh script is as follows:
---BEGIN FILE---
sleep 10
scsidev="`echo ${1} | sed s/umass/umass-sim/g`"
diskdev="`camcontrol devlist -v | grep -A 1 ${scsidev} | tail -n 1 | \
awk -F "(" '{ print $2 }' | awk -F "," '{ print $1 }'`"
fstype="${2}"
mountpoint="${3}"
mount -t ${fstype} /dev/${diskdev} ${mountpoint} 2>/dev/null
mount -t ${fstype} /dev/${diskdev}s1 ${mountpoint} 2>/dev/null
END FILE
First, the script has to sleep because the device doesn't immediately show
up in the CAM device list. After waiting long enough to be safe, the script
takes the device name passed by devd and uses it to parse the device name
from the output of `camcontrol devlist`. GEOM doesn't automatically read
the partition table and create the slice device, so the script forces it to
do so by trying to mount the base device before mounting the actual
partition.
These tricks are ridiculous, IMO. There has to be a more intelligent means
of going about this. How do I get the scsi disk device name created for a
umass device as soon as it's created? How do I inform GEOM that it needs to
add a new MBR to it's configuration and create the appropriate /dev/da?s*
devices?
