Hi!

I recently acquired an mp3 player and, of course, tried to use
it with NetBSD.

I didn't have much luck on my main work station running 3.99.15/i386
-- very quickly after I start copying files to it, there is a umass
error and the transfer hangs. Usually, umount -f doesn't work and
I can't shutdown cleanly.

Relevant lines from dmesg:

Another time the error was

umass0: at uhub4 port 5 (addr 2) disconnected

The same mp3 player works fine at an ohci I have in another machine,
running 3.99.9/macppc.

Ideas?
