There is also a dev-discussion going on about zfs commands hanging
on some long tasks, as it is a problem which annoys (to say the least)
or has annoyed several people including myself, so I'll make a copy
to that list too. "+1" on "this bug bites us" part.

Maybe, at least, it is technically possible for a USB driver to hang -
I've seen that a lot with Solaris 8/9 on some older projects of mine.

I think some people on the zfs-discuss list might help if you give
some more detail (a concise summary of this thread in one post) on
what is going on with the system - what it is, what you did with the
drives, what is the pool busy with until it hangs...
