For the record; I can confirm that the solution posted by Kent Tenney also works for me in Hardy Heron 8.04.
I have a generic no-name external USB case for ATA drives. When trying to mount an IBM DeskStar 40GB disk (IC35L040 AVER07-0) I first got the following messages in /var/log/messages: [ 1155.095613] usb 3-1.3: new high speed USB device using ehci_hcd and address 11 [ 1155.216151] usb 3-1.3: configuration #1 chosen from 1 choice [ 1155.229398] scsi4 : SCSI emulation for USB Mass Storage devices [ 1165.750265] scsi 4:0:0:0: Device offlined - not ready after error recovery [ 1165.750989] usb 3-1.3: USB disconnect, address 11 The adapter was not visible through lsusb and the drive could not be mounted. Switching the drive jumpers from CS/Cable Select to drive 0 primary master made auto-mounting work with the following output: [ 1929.136861] usb 3-4: new high speed USB device using ehci_hcd and address 13 [ 1929.281381] usb 3-4: configuration #1 chosen from 1 choice [ 1929.297936] scsi6 : SCSI emulation for USB Mass Storage devices [ 1934.303006] scsi 6:0:0:0: Direct-Access IC35L040 AVER07-0 0811 PQ: 0 ANSI: 0 [ 1934.318784] sd 6:0:0:0: [sdc] 80418240 512-byte hardware sectors (41174 MB) [ 1934.320664] sd 6:0:0:0: [sdc] Test WP failed, assume Write Enabled [ 1934.322581] sd 6:0:0:0: [sdc] 80418240 512-byte hardware sectors (41174 MB) [ 1934.326566] sd 6:0:0:0: [sdc] Test WP failed, assume Write Enabled [ 1934.326585] sdc: sdc1 [ 1934.347731] sd 6:0:0:0: [sdc] Attached SCSI disk [ 1934.347873] sd 6:0:0:0: Attached scsi generic sg3 type 0 The adapter now appears correctly as a USB device: $ lsusb Bus 003 Device 013: ID 05e3:0702 Genesys Logic, Inc.
