you have to restart usbd.  usbd doesn't handle device ejection as far
as i can tell.

this is because rio puts each window in a sepeate namespace.  there are
two ways around this.  first, start this before you start rio.  (alternatively
use the plumber to give all new windows access.  plumb a string like
	Local 'cmd for everyone to see'
) alternatively, you can use /srv to post the fd.
