[nvda] no braille on my display, please help

Hi Jamie and others,
I installed the following:
libusb 0.1.12
brltty
the newest snapshot today. I can select brltty but my brailledisplay still acts as dead. 
What to do?
Can theproblem be that it's original manifucturerdrives are also installed? But if they're not a cannot add it with the nw hardware wizzard. 
it's a tieman voyager.
when runnig the libusb test program i don't see anything with nvda no liss i can scroll with cursor or tab key only silence. 
Hope you can help me to make braille work on my side.
Dick
