I had experience to the contrary with 5.2.1:

http://www.freebsd.org/cgi/getmsg.cgi?fetch=24565+28404+/usr/local/www/db/text/2004/freebsd-hardware/20040926.freebsd-hardware

Btw, I had actually tried to use the latest sys/dev/usb/ehci* files from
CVS with the rest of 5.2.1 files (backing out only
bus_alloc_resource_any() change) and I had exactly the same problem, so
it seems that either this problem is not fixed in CURRENT or the problem
is not local to ehci code e.g. it is in umass/ehci interaction.
