USB 6008 Digital output high is only 0.07 V

My USB 6008 Digital Output high is limited at 0.07 v and it is consistent.

I tested all digital lines, analog input reads them at same voltage. Compared the voltages on multimeter to see if ai pins are alright. The voltage reading matched measured ai values. If I disconnected ai- from gnd, the voltage floats by 1.4v, as mentioned in the manual. The output sources 5v and 2.5v are also not showing their rated voltage.

I tried disabling "USB selective standby". Observed no change in output.

I want to know if there is anything else I can do to verify if its working... or is it broken?

Thanks
