io-graphics

Good Afternoon, I need Your help in resolving next question : for starting qt(photon) I have to start io-graphics utility, I’m trying start it in next way (QNX 6.5.0 Neutrino):
io-graphics -d vid=0x1022 did=0x2081 deviceindex=0
And get message :

Process <process_id> io-graphics exited status=1

What I do wrong with it? Any help is appriciated.
Thank you in advance.
