Error -28 is -ENOSPC, which means the USB bandwidth was exhausted. Too many devices were plugged into the same controller. Unplugging some of the other devices ought to help. Or even plugging the BT controller into one of the other ports rather than the external high-speed hub, since it is only a full-speed device.
