I have done it many times, an I have never had a single problem.  I simply
hooked up my butterfly's uart pins to a 9 pin serial connector, opened up
Bray's Terminal, set it to show me hex  output, tell it to connect, power up
the bfly and then press up on the joystick and you should see a string of
characters (they should be '?' if you have your baud set correctly,
otherwise adjust your baud rate in the terminal.)  If you can see these
characters then you have things setup correctly, if not something is wrong.
Once you can see get to this point, you can move on to having your bfly's
program send you data.  My butterfly works just fine with at least 7
different computers including a Pentium II laptop, an AMD64 laptop, and P4,
P3, AMD64, and AMD sempron based desktops... So either your butterfly has
issues or you have something setup incorrectly.  Check out AVRfreaks, there
are tons of people using butterflies, and there are numerous link on getting
them to communicate with the PC.
	As it is, how are you programming it without being able to receive
data from it? (not using the bootloader?)
