    Hi Folks

    Have recently got an HP-7200 external CD-RW drive...and can't
    get it to work! I have read all the archives of this list...but
    none seem to be having the kind of problem which I face.

    I have an AMD-K6-500 running RH 7.0. I have an internal Creative
    CD-ROM drive also. I have NO SCSI controllers/devices.

    I started with the usual setup, loading paride, epat and pg.
    got the following dmesg output
    ---------------------------------------------------------------
    [root@gh-1194 /root]# insmod paride
    Using /lib/modules/2.2.16-22/misc/paride.o
    paride: version 1.04 installed
    [root@gh-1194 /root]# insmod epat
    Using /lib/modules/2.2.16-22/misc/epat.o
    paride: epat registered as protocol 0
    [root@gh-1194 /root]# insmod pg
    Using /lib/modules/2.2.16-22/misc/pg.o
    pg: pg version 1.02, major 97
    pg0: Sharing parport0 at 0x378
    pg0: epat 1.01, Shuttle EPAT chip c6 at 0x378, mode 5 (EPP-32), delay 1
    pg0: HP CD-Writer+ 7200, slave
    [root@gh-1194 /root]#
    ----------------------------------------------------------------

    So far so good? Then cdrecord -scanbus still does not help.

    ----------------------------------------------------------------
    [root@gh-1194 /root]# cdrecord -scanbus
    Cdrecord 1.9 (i686-pc-linux-gnu) Copyright (C) 1995-2000 Jrg Schilling

    scsibus0:
    cdrecord: Inappropriate ioctl for device. Cannot send SCSI cmd via ioctl
    ----------------------------------------------------------------

    So I load the ide-scsi module.

    --------------------------------------------------------------------
    [root@gh-1194 /root]# insmod ide-scsi
    Using /lib/modules/2.2.16-22/scsi/ide-scsi.o

    sr0: scsi3-mmc drive: 0x/52x cd/rw xa/form2 cdda tray
    ----------------------------------------------------------------------

    Note that there is no mention of the CD-RW here. But cdrecord -scanbus
    seems to work!

    --------------------------------------------------------------------

    But try running cdrecord...and see what happens

    ------------------------------------------------------------------
    [root@gh-1194 /root]# cdrecord -dev=1,0,0 -inq

    ------------------------------------------------------------------

    Am I missing something...forgot to load some module, maybe?
    Please assist me.
