MITSUMI USB FDD with USB4BSD does not work, neither

I have a MITSUMI USB fdd and pluged in to 8-CURRENT.
FreeBSD 8.0-CURRENT #5 r189058M: Thu Feb 26 11:29:13 EST 2009

It printed as following but nothing happened there after.

ugen0.3: <MITSUMI> at usbus0
umass0: <MITSUMI MITSUMI USB FDD, class 0/0, rev 1.10/1.00, addr 3> on usbus0
umass0:  SCSI over Bulk-Only; quirks = 0x0100
umass0:0:0:-1: Attached to scbus0


Actually, this device stopped working from 7.0-REELASE.
