There should'nt bre any problem with the CD-RW. To set it as master first, set the jumpers to the master position (usually there's a little diagram on the drive, failing that, take a look on the manufacturer's website), then, plug the IDE cable in so that the CD takes either of the end plugs (there will be 3 on the cable -- the middle one must be used for the slave device or left empty).

To run lsusb, just open a terminal (the TV screen icon at the bottom left) and type

lsusb <enter>

and it should show you (albeit in rather too much detail) all the usb devices found.
