USB portable drive weirdness

[Peter King]

I put a 2.5" drive in a portable enclosure, for backing up and transferring
files, which connects to and draws power from a USB 2.0 cable. It works just
fine on my laptop. Well, I plugged it into my desktop yesterday, and -- well,
nothing. I mean nothing at all: no sign in dmesg that it even registered. It
just wasn't there.

OK, I thought, somewhere along the line I probably haven't loaded the right
USB modules, or USB_mass_storage, or whatever. Then I plugged in my USB flash
drive. Came right up, recognized by dmesg, mounted just fine as a USB weapon
of mass storage. So the USB subsystem seems to be working.

Tried the portable drive once more. Again, nothing. The drive light comes on
so it *is* drawing power -- but no registration in dmesg. So I plugged it in
my laptop, and there it is, no problem. Back on the desktop, nada.

What is going on here? Any ideas?
