Most recent kernel where this bug did not occur:version 2.6.8 or (maybe!!)2.6.10
Distribution:Slackware_10.2, REDHAT_9, ASPLinux10 and probably all the others
Hardware Environment:HP CD WRITER 82xx series / Pentium MMX
Software Environment:Slackware 10.2
If I'm not wrong , since version 2.6.11 the driver for USB CD WRITER doesn't
exist. Now there is only USBAT/USBAT2 driver that detects this device not
as /dev/sr0 and not as /dev/scd0. Now it is /dev/sda and driver can not
understand that it is a cdrom. When you try to mount it or detect it
with "hotplug" CD-WRITER starts some silent knocking (?!!). I'm not a
programmer but I think that it tries to use the wrong protocol and tries to
enable writing function like on an usual SCSI Hard Disk.
Steps to reproduce: maybe there is a reason to return the old good v.2.6.8/2.4
Please reproduce this on 2.6.18-rc5 or newer
Please reopen this bug if it's still present in kernel 2.6.19.
