Any chance these speakers need a USB 2.0 port, and all the ports
on your FreeBSD box are 1.x? I don't remember the USB power spec
offhand, but 2.5W may exceed what a USB 1.x port can supply --
a limit that applies regardless of the system's overall power
provisioning.
500 mA is 5 unit loads for USB 2.0, or powered hub territory. The
device has to request that high power mode, and the system can say no
and disable the port. That should show in /var/log/messages.
