This is a known issue, especially with USB devices and/or newer hardware. 
Search the archives for btx issues if you want the gory details. A fix 
was committed several weeks ago, but still after the release of 7.0. Try 
using a 7.0-STABLE snapshot from 
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/200804. Those images should 
all have the new btx/boot code. You will need to reinstall the boot 
blocks on your usb drive, so starting from scratch with the new CD image 
could be the simplest way to go.

HTH,
