USB_Analogic potmeter values in sioc

[ronnev]

Hi.
Have this problem trying to get a motorized throttle going:

VAR 2325, name FlapPOT, static, Link USB_ANALOGIC, Device 42, Input 4, PosL 10, PosC 122, PosR 255 (Have also tried another variable number)

The values in IOCP console (FlapPOT=504), differs from the ones in SIOC monitor (#4=178). see attachment. This only when using sioc 7.0.3b which comes whit io4fs. I'm experiencing this with all the potmeters on the USBDCMotor card from OC.
When i run the same script in sioc 8.0 the values are the same and correct (0-255).
Any suggentions?
