I'm trying to get a Addronics 5-Port HPM-XU (USB/ESATA) port multiplier to

device while in non-RAID mode.

Since my crashbox is a notebook without SATA, I tried to get USB to work
first.  The thread on that is at:

     http://marc.info/?l=linux-usb&w=2&r=1&s=addronics&q=b

(note the misspelling of addonics).

My interpretation of what was going on there is that the second disk is
assigned a SCSI LUN of 1, but that's not handled properly.

Now I'm trying to get it to work via ESATA, and I'm having a similar experience
(before I got errors, but now nothing).  I'm assuming a similar thing is going on
here, except that my (weak) reading  of the source has it not sending LUN's
at all.  So the second disk isn't seen at all.

What information do you need to help me out?

Well, there's not really such a thing as LUNs with SATA - for it to show 
up as multiple drives it would have be identified as a port multiplier 
instead of a single drive. What shows up in dmesg when the device is 
connected?
