--- Comment #24 from Alan Stern (stern@rowland.harvard.edu) ---
In view of comment #17 plus the fact that the entire system freezes, this looks
more likely to be a PCI issue rather than a USB problem. A broken USB host
controller isn't the sort of thing you expect to take down the whole computer,
but a broken PCI bus or controller could easily do so.
