cmdline_launcher  -device question
hi i am running nanominer with cmdline_launcher

"cmdline_launcher.bat -mport -4068 -algo cryptonightr -wallet 1QGADhdMRpp9Pk5u5zG1TrHKRrdK5R81TE.1070 -rigName x -pool1 cryptonightr.jp.nicehash.com:3375"

what would i need to add to this if i have a 4 card rig and would like to disable device 0?

eg.
have tried adding -devices 1,2,3  -devices=1,2,3

any help be very much appreciated
