mount issue on FC2.B (no CD, DVD, usb camera)

[Jean-Patrick Pommier]

Dear all,

I installed a fedora FC2.B from DVD. After installation, it is
impossible to mount an amovible device (CD, DVD, usb camera).

When I try to mount a DVD (from KDE or gnome), I get ... n'est pas un
périphérique valide de type bloc (not a valid block device...)

After some googling I tried:

"dmesg | grep hd" which gave

Kernel command line : no root=LABEL /hdc=ide-scsi rhgb
hdc slimtype COMBO LSC-24082, ATAPI CD/DVD-ROM drive

So I tried "mount /dev/hdc /mnt/cdrom", result:

/dev/hdc n'est pas un périphérique valide de type bloc

In fstab, there is
/dev/cdrom /mnt/cdrom cdf, iso 9660 noauto, owner, kudzu, ro 00

kudzu detects (from /etc/sysconfig/hwconf):

CDROM desc slimtype COMBO LSC-24082K
bus SCSI
device scd0
driver ignore
host 0
channel 0
lun 0
generic sg0

So I tried "mount /dev/scd0 /mnt/cdrom"

result ... "/dev/scd0 n'est pas un périphérique valide de type bloc"

Let see the modules : "/sbin/lsmod" gave (at least):
scsi-mod
uhci-hcd

I also tried "eject /dev/sr0",It doesn't eject anything

I have also been told to try "cd /dev" and "./MAKEDEV".  I get a message
regarding the correct way to use MAKEDEV ...

The config:

laptop PCTeck
dual boot XP/fedora FC2.B (kernel 2.6.6)
chipset VIA, CPU nehemia 1GHz, GPU VIA CLE266
DVD/CDRW slimtype COMBO LSC-24082K

Any advice?
    *A simple way to fix the stuff
    *Reinstalling FC1 + upgrading everything but Kernel 2.4?
    *Back to FC1? (It works)
    *Waiting FC3?

Thank you

PS
 No sound too.

Try to remove ide-scsi part from kernel command line and reboot.
ide-scsi is obsolete in kernel 2.6'

Remove 'hdc=ide-scsi' from the command line. You do that by going to
/boor/grub/grub.conf and CAREFULLY erasing that part only.

Then go to /etc/modprobe.conf and comment out by prepending a '#'
symbol any line that has ide-scsi in it. :-)

Thanks a lot. It seems easy.

I think I may get this problem due to a previous install of a FC1
because I did not modify/update grub (I was afraid to loose the dual
boot XP/FC2)
