Help. Cursor/pointer interference and Z axis randomly raises

I’ve got the crossfire with IHS/THC upgrade. Ive noticed that the cursor on the PC has choppy or no motion while the Crossfire control box is powered up. If I shut off the control box the cursor travels across the screen normally. I’m stuck using the mouse pad thats built into the Laptop because Ive only got 2 working usb ports. one for flash drive and the other to the crossfire. Has anyone had this happen and what is the solution. Also, the Z axis will randomly raise while I’m navigating through Firecontrol. I think the two issues are related.

Is your laptop charger plugged in? That is a known cause of ground loop interference on these machines.

The problem persists even when the charger is unplugged.

get some ferrite chokes and install them on the lines…
