Still no fix.  OS is as follows:

FreeBSD localhost.my.domain 4.5-PRERELEASE FreeBSD 4.5-PRERELEASE #0: Wed Jan  9 09:37:46 CST 2002     root@localhost.my.domain:/usr/obj/usr/src/sys/LOCAL  i386

Which includes that "E-series" update.

Camera is recognized by usbd, but if I try to mount() it I get
a panic-message viz:
Fatal trap 18: integer divide fault while in kernel mode.
(And what appears to be a register scoreboard or a stack-trace
or something; is there a way to capture this?)

Then a panic & reboot.  I guess it's better than "before" -
previously I got no message whatsoever; the OS just froze &
rebooted.  At the same time I'd think a panic/reboot is Very
Very Bad; at least if something is "wrong" shouldn't the OS
"just say no?"

Here are the related pices of the kernel config:

# SCSI peripherals
device		scbus		# SCSI bus (required)
device		da		# Direct Access (disks)
device		sa		# Sequential Access (tape etc)
device		cd		# CD
device		pass		# Passthrough device (direct SCSI access)
.
.
.
# USB support
device		uhci		# UHCI PCI->USB interface
# device	ohci		# OHCI PCI->USB interface
device		usb		# USB Bus (required)
# device	ugen		# Generic
# device	uhid		# "Human Interface Devices"
# device	ukbd		# Keyboard
# device	ulpt		# Printer
device		umass		# Disks/Mass storage - Requires scbus and da

I think the kernel config is ok, because everything works fine
with a USB Zip drive.  Any other ideas
