Another xbit sucker, same exact issue for me. I have tried xp sp1, xp sp2, win 98se, using all versions of xbit software and still have the same issues as described above. NO OTHER USB devices are plugged in any of the pc's that I have tested. There is definately something we are missing here. I have installed the old xbit 1.0 version without any issues, the new 1.5 is jacked up. Any idea where we can buy the old version? Thanks
