Hi Roland,

I had to rebuild the kernel without umass in it first, but here's the 
result.

It attaches the device as an ata rather than umass - but no devices are 
created for the slices/partitions on the disk.

atausb0: using SCSI over Bulk-Only
ata2: <USB lun 0> on atausb0
/boot/kernel{105}# ls /dev/ata*
/dev/ata
/boot/kernel{106}# ls /dev/ad*
ls: No match.
/boot/kernel{107}# kldstat
Id Refs Address    Size     Name
  1   10 0xc0400000 4e1cb8   kernel
  2    1 0xc08e2000 21ef8    linux.ko
  3    1 0xc0904000 65de0    acpi.ko
  4    1 0xc5898000 5000     atausb.ko
  5    1 0xc589d000 d000     ata.ko
/boot/kernel{108}#

I've only tried it on 6.3 at the moment and atausb/Makefile didn't 
exist, so I copied it from 7.0, it built and installed without error, 
the module kldload'd without error, and it finds the device so I assume 
it should be OK in 6.3 even though the Makefile doesn't get cvsup'd?

Regards,

Mark
