/dev? for USB dvdrw drive?
On my backup 2.4.26 kernel the mount point for my Sony dvdrw drive is
/dev/sr1.
When I boot to my 2.6.8 kernel /dev/sr1 does not exist. The drive is
recognized by lsusb but this just gives the bus # and device #.
This must be because scsi emulation is on for the 2.4.26 kernel but not
for the 2.6.8 kernel. When I compile a 2.6.8 kernel with scsi emulation
hotplug crashes the system when a usb device is unplugged.
I understand that scsi emulation should not be needed with a 2.6.8
kernel and, indeed, I can access my cdrw drive at /dev/hdd with cdrecord
with dev="ATA:1,1,0"
I don't remember how I determined that the dvdrw drive was located at
/dev/sr1 when running with the 2.4.26 kernel. When I connect a USB
jumpdrive while the 2.4.26 kernel is running, the /dev/ mount point is
reported. This does not work with the 2.6.8 kernel and neither kernel
shows the mount point of dvdrw drive when it is connected.
I'm sure there is some elementary way to determine the mount point but
it escapes me. I would appreciate being pointed in the right direction.
