    Hello,

    I've upgraded to 5.4-RC1 and I'd like to access an Mpman MP3 Player
    via USB.

    When I attach the USB device several messages appear and the Mpman
    displays "Starting" but then /dev/da0 is not available.
    The messages look like this:

    11:12:22: umass0: vendor 0x10d6 Generic USB Disk Device, rev 1.10/1.00, addr 2
    11:12:22: da0 at umass-sim0 bus 0 target 0 lun 0

    11:12:24: Opened disk da0 -> 5
    11:12:24: umass0: detached

    For comparison 5.3 calls the kernel debugger and NetBSD waits a
    little longer and then allows access on the Mpman.

    Can I make 5.4-RC1 allow accessing the Mpman?
