There is no flash onboard, just a small serial eeprom.  Is the LED
flashing?

The most common problem is blown fuses.  A number of people have
reported them.  I personally have only had one blown fuse in the entire
3 years I've been doing this, and that was when I plugged in a
daughterboard with power on.

The only other thing I've seen is that your computer getting hit by
lightning will kill the USB interface on the FX2 chip, but it will still
flash the LEDs.
