mount ugen0 ENE Flash UB6250 memory card?

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

(Yesterday posted about this to netbsd-users.)

When I insert a memory card, I see:

ugen0 at uhub4 port 5
ugen0: ENE Flash UB6250, rev 2.00/1.00, addr 3

But no umass in the dmesg output nor sd associated with it.

When I boot with "disable ugen*" I get:

ENE Flash UB6250, class 0/0, rev 2.00/1.00, addr 3, uhub 4 port 5 not 
configured

Any ideas? Do I need to have support for it if using ugen0 instead?

This is i386 netbsd-MONOLITHIC built today.

(On a different hardware, also running NetBSD, I can mount it easy using 
sd -- which uses umass.)
