Hog4Pc + Hog 3 Playbackwing: 'Ghost Fader' / Faders changing value

Hello,

I've the following setup: Hog 3 Playback Wing + Hog 3 Programmer Wing + Hog 3 Superwidget connected to a Laptop running Hog4PC (latest Version). 

When connecting the hardware to the software everythings works as expected beside the fact that all Faders start to 'shake'. They jump +-1% around the value they are set to. Eg if I set INT to lets say 58% the value will flip between 57-59%. This jumps between values happen on all faders simultaneously and appear to be somehow random. The problem is also visible: the Faders visualized by the software shake. 

I have to admit that I modified the Hardware: I just use the front panels and the interfacing PCB's of the playback and programmer wing built into a Peli Gun case with a Dell touchscreen. Widget + Wings are powered by one industrial quality PSU.

However: This Setup worked great in the past so I wonder if somebody had similar problems once...

- I double checked all USB cables
- I tried different versions of HOG 4 PC
- I checked the cables from the front panels to the interfacing PCB's 
- I appears that the faders get more 'shaky' when I apply pressure to the front panel

Any thoughts how to solve this problem are very appreciated.

Thanks & Regards,
Georg
