That worked, with a bit of fiddling.

I had in the original config file:

device "USB Stick"
        devname "umass0"
        attach "echo foo >/dev/console"
        detach "echo bar >/dev/console"

This didn't cause the detach event script to be run. Figuring that the
vendor/product/release IDs would be more helpful, I rewrote it thus:

device "USB Stick"
        devname "umass0"
        vendor 0x08ec
        product 0x0834
        release 0x0100
        attach "echo foo >/dev/console"
        detach "echo bar >/dev/console"

But that didn't work, either. Only with this entry does the detach
event run:

device "USB Stick"
        vendor 0x08ec
        product 0x0834
        release 0x0100
        attach "echo foo >/dev/console"
        detach "echo bar >/dev/console"

i.e. without the "devname" clause. Perhaps that messed up usbd's
match-seeking algorithm? Anyway, it works for me now, so I'm happy.
