Yes, there is a dmesg error:
ugen4.5: <(null)> at usbus4 (disconnected)
uhub_reattach_port:435: could not allocate new device!
But then just a few lines later, dmesg says:
ugen4.5: <Seagate> at usbus4
umass1: <Seagate Portable, class 0/0, rev 2.00/1.30, addr 5> on usbus4
umass1: SCSI over Bulk-Only; quirks =3D 0x0000
umass1:3:1:-1: Attached to scbus3
da1 at umass-sim1 bus 1 target 0 lun 0
da1: <Seagate Portable 0130> Fixed Direct Access SCSI-4 device=20
da1: 40.000MB/s transfers
da1: 305245MB (625142448 512 byte sectors: 255H 63S/T 38913C)
I'm thinking there's some sort of power management scheme in the=20
Seagate that umass has trouble accommodating.
--=20
