Playing around with debug flags, I found out that I/O doesn't hang at all
when I set hw.usb.ehci.debug=15. The transfer seems slower than it could
be, though, and the machine becomes almost unresponsible until it's done
(i.e. switching from one window to another in X or typing a command in an
xterm takes a while).
