Curious, either it didn't show the plug-in information, like what I
showed you recently, or you didn't copy it in. No big deal, as the
fdisk results show what we need.

Obviously it's there.

Again, obviously there.

Right. The left hand value (0457) is the manufacturer's ID, which will
be the same for all of the manufaturer's products. The right hand one
(0151) is for the specific product. I think they should have changed
it so their own manufacturing processes could tell them apart, but
that doesn't affect us here.

Anyway, the things are clearly working correctly under FC3. I've seem
other USB devices work on one version of Linux but not another. So my
guess is that there is a bug, either in FC5 or in FC5_64. It would
help to have an FC5_32 machine to narrow things down. We'll see what
lsusb reveals.

Odd. "yum provides lsusb" got no hits. It should have returned
"usbutils", which is the package you want. I wonder if that's a bug in
yum?

BTW, you could have gone to the FC3 box and run "rpm -qf $(which
lsusb)" to get the package name, but you didn't know that.
