Hmm, ok, looks fine... I've never used the /proc/scsi filesystem (the current
kernel config says it's deprecated, don't know what the 2.4 kernels said),
so I'm not used to its output; you could have a look at

/sys/bus/scsi/devices

and, even more interesting,

/sys/bus/scsi/drivers/sd/

and look if your HP Drive is listed there (there should be a symlink to
/sys/devices/(pci bus and device)/(usb bus and device)/(target id)).

Besides that, I haven't got any more clues at the moment... maybe someone
more knowledgeable can help here.

Oh, one last thing I was wondering about: Here's my syslog output
(2.6.10, SCSI generic compiled in, SCSI disk (sd) as module, usb-storage
as module, no hotplug at all, no devfs/udev):

You only showed us an excerpt from /var/log/messages, and what goes there
is dependant on /etc/syslog.conf, but here's the comparison between your
and my /var/log/messages:

Note that my SCSI layer is reporting the drive back, including the
calculated size (it's doing it twice, probably because usb-storage's
"waiting for device", but never mind)... do you get this type of message
("SCSI device sda: ...") when your SATA drive is recognized? Maybe the
USB drive isn't detected as a true disk by the SCSI driver...
