You did not say what release of Freebsd you are running.
Pick one pc to test on and report results from that one only.
Are you saying you have all those devices plugged into individual
USB ports at boot time?
Are all your USB devices coded in /etc/fstab
What version of USB (1, 2, 3) is your flash drive designed for?
Have you tried different manufactures of flash drives?
Post your /etc/fstab dmesg for usb, output of usbconfig command, draw
diagram of your usb device configuration.
