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

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?
