I'm not sure that any echo has ever supported special escape chars.  
Maybe it's some Gnu/Linuxism?  /bin/echo does the same as csh echo and 
the man page mentions no -e flag.

Try printf.

printf %b "/dev/da0s1\t /mnt/usb\t msdos\t rw,noauto\t 0\t 0"

Why aren't you adding a newline?  Do your command twice and you have a 
broken fstab :-(

printf %b "/dev/da0s1\t /mnt/usb\t msdos\t rw,noauto\t 0\t 0\n"

would, imho, be the right incantation.
