[Tfug] USB hang

[erich]

I know,
           I can't test the "bad hard drive" theory because this is the 
only SATA machine
that I have. One would like to drop the drive into another SATA machine 
and see
what happens.
           At this point I can answer only one of your questions: 
Mythdora 12.

Sounds like the answer is "no".  A USB device can't wreck a USB system.

PS: It's USB 2.0, and this Knoppix can handle it.
