I changed US_SC_SCSI to US_SC_RBC but it doesn't help. I found the Windows driver of LaCie is the same for both LaCie USB Hard Disk 0x059f/0x601 and 0x059f/0x602 Mass STORAGE product. FYI with Windows ME and LaCie driver, the device works without problems on the same machine. I have a Toschiba IDE DVD ROM drive with ide-scsi emulation and the LaCie USB CDRW. uname -a Linux jungle 2.4.19-pre3-jp8 #2 Mon Mär 18 21:08:18 CET 2002 i686 unknown After booting, I get a wrong ANSI SCSI revision. jungle:/home/joerg # cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: TOSHIBA Model: DVD-ROM SD-C2502 Rev: 1D13 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: IDE-CD Model: ReWritable-2x2x6 Rev: 3.01 Type: CD-ROM ANSI SCSI revision: ffffffff I don't know if this is correct behavior, but the USB device is *not* recognized as an SCSI device when it is attached *after* booting. I have to power down the machine and do a cold restart before it got attached as SCSI emulated device. A warm restart (reboot) does not help. Using cdrecord to create an audio cd gives an 'illegal request', followed by 'media' and 'hardware errors' reported by the SCSI subsystem. The drive is powered and filled with a writable CD-R. jungle:/home/joerg # cdrecord -v dev=1,0,0 speed=2 -audio -pad -dummy /tmp/01\ -\ Jose\ Padila\ -\ Que\ Bonito.wav Cdrecord 1.11a05 (i686-suse-linux) Copyright (C) 1995-2001 Jörg Schilling TOC Type: 0 = CD-DA scsidev: '1,0,0' scsibus: 1 target: 0 lun: 0 Linux sg driver version: 3.1.22 Using libscg version 'schily-0.5' atapi: 1 Device type : Removable CD-ROM Version : 2 Response Format: 1 Vendor_info : 'IDE-CD ' Identifikation : 'ReWritable-2x2x6' Revision : '3.01' Device seems to be: Generic mmc CD-RW.
