I have a E6320 with a swappable DVD/CD reader/writer (swaps with the second battery). Under precise it's not recognized when it's hot plugged it's not recognized. The computer needs to be restarted for it to be recognized. If it's in place when the system is booted, then it's recognized fine.
Hot plugging worked unter natty and oneiric (I didn't have this system before that).
WORKAROUND: If I unplug and replug the device once it's been booted with it, then it works.
