wow...so someone else is having the same issues.
This is what my cli enumerate is coming out with
localhost office # 4L-cli enumerate
Drive path: /dev/sr0
Full name: ATAPI - DVD A DH16A6L - ZH1A
Model: DVD A DH16A6L
Drive inner radius: 58
Drive outer radius: 0
My cd and dvd burns fine but the light scribe gives me problem. The same communication error which you got.
I'll appreciate if you stumble upon a solution for this, please do post it...even I'll do the same. Even I am hunting for a solution for this.
