描述：
1.從ports安裝 k3b
2.啟動 k3b, Settings -> Configure k3b -> Devices -> Readonly Drives & Writer Drives 全部為none
3.點擊“Add Devices”，輸入/dev/acd0, 系統提示錯誤信息：Could not find an additional device at /dev/acd0
解決辦法：
1.重新編譯內核, 確認添加了最後一行
> > device scbus # SCSI bus (required for SCSI)
> > device ch # SCSI media changers
> > device da # Direct Access (disks)
> > device sa # Sequential Access (tape etc)
> > device cd # CD
> > device pass # Passthrough device (direct SCSI access)
> > device ses # SCSI Environmental Services (and SAF-TE)
device atapicam
perm acd0 0666
link acd0 cdrom
link acd0 dvd
perm pass0 0666
perm cd0 0666
perm xpt0 0666
devd_enable="YES"
4.以root賬號執行
#cd /usr/local/bin
#chmod u+s cdrdao
5.重啟以後, k3b就會提示找到了刻錄機。
