usb harddisk not working

[tech-lists]

Hi,

I've found that it can take a little time for the usb/usb3 
subsytem to finish its hw probing after boot. This causes 
problems if there's attached usb3/zfs storage you want 
automatically started on boot. The following lines in 
/boot/loader.conf helped me:

kern.cam.boot_delay="20000" # 20s delay for usb3 to wake up
vfs.root_mount_always_wait=1 # give usb time to settle before zfs
