Hi,
I've tested ASUS USB2.0 CD-RW 40x/12x/48x under 2.5.53.
The CD-RW device cannot be mounted. but it shows in
/proc/scsi/usb-storage-0/0.
Run "cat /proc/scsi/usb-storage-0/0", I got
***

Attached: Yes
***
Run "dmesg", I got
****

Any idea? Thank in advance.

Are you sure you have all of the scsi modules you need loaded? The
dmesg output looks fine, what happens when you try to mount the drive?
And does this drive work with older 2.5 kernels, or 2.4?
thanks,

I think I've made all scsi modules I need built-in kernel.
(usbcore, ehci-hcd, usb-storage, sr_mod, sd_mod) Do I miss something?
Also, I've tested the ASUS CD-RW under kernel 2.5.45 and it worked.
But in the kernel 2.5.53, the system shows below when I try to mount the
CD-RW.
** #mount /dev/scd0 /mnt/usb-cd
** mount: /dev/scd0 is not a valid block device
There is one thing I forgot to say before.
I've checked the /proc/scsi/scsi file by running "cat" when I pluged the
device, and it shows below.
** Attached devices: none
Thanks in advance.
BR,
Joseph

Check that you actually have /dev/scd0. I think it should be:
# mknod /dev/scd0 b 11 0

I've checked the node as follows.
#ls -l /dec/scd0
brw-r----- 1 root disk 11, 0 Sep 9 13:24 /dev/scd0
Any idea? Thanks in advance.

Ouh, could you post your /proc/devices ?

Yeah, that is shown below.
BTW, the ehci-hcd module seems instable. because the CD-RW can work
sometimes.
But it cannot work sometimes. So curiously. ?_?
