Someone else just reported a similar issue with usb and the 1.11 beta, so there seems to be a bug.
regarding the cv input on 1.05, this can only be a calibration issue. Can you boot into 1.05 and check the settings in MISC->EXPERT->ADC/DAC CAL ?
OR (if you have HW v. 17) you might need to do this:

(but only if you have HW17)
