Has anyone out there actually got a drive > 2TB working via USB on
an illumos distribution? My attempts so far have failed (oi151a7, oi151a9,
and XStreamOS), with my 3TB drive in a USB-SATA enclosure appearing as
a 2TB drive. The same drive/enclosure works perfectly when attached
to MacOS-X via USB, and the same drive/enclosure works fine when attached
by its eSATA connection to my illumos-based systems.

[2nd attempt - first vanished into a black hole]
I had a quick look through scsa2usb.c (not that it's an area I know),
and I can only see it using Group 5 (12 byte) SCSI commands. This will
limit the addressing to 2^32 blocks, which is 2TB for a 512byte/sector disk.
So if I'm right, this is a limitation of USB-connected drives on Illumos.
