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
