Yes! It seems that this time you hit the nail in the head. I booted my
system (7 boots in a row, both cold and warm boots) with the new patch
applied and, for each boot, I plugged the drive and it was promptly
recognized after I loaded uhci-hcd and usb-storage.
I think that the probability of this being just sheer luck is so low,
given the probability of success of it working that I can say that now I
think that it is working for good with your newest patch. :-)

The Sindows logs are wrong here, because the drive doesn't have an
external power source. It is just a "keychain" USB Drive that gets its
power from the USB bus.
But the patch had a side effect, which I have not yet identified
completely. It seems that if I plug the drive, without having X started,
and then start X, my psaux mouse doesn't work.
It also seems that a cold boot with starting X and *then* loading the
drive cures the problem, but I am not sure of what I am saying here.
The logs of one of the successful sessions are here:
