So for example on my freebsd system I would dd as follows:
dd if=/path/to/foo/hex-i386-1.0.3.usb.img of=/dev/da0 bs=1M
command is simple... if is the Input File, output is the Output File (in this case it is the da0 device) and bs=1M is setting the block size to 1mb - this helps to speed up the write process.
