10k ohms ”insulation” between the USB port and the table (with unit powered on) came directly from Langmuir Systems tech support, Jim.
Screenshot from Austin’s conversations with the same technician I am also working with.
Thomas confirmed to me that I should have the 10k ohm reading as well, but wrote off my readings above 10k ohms as either equipment or user error with my meter.
Since then I have confirmed that my meter is accurate, and I’m still not getting the required 10k resistance value, which seems to point towards a USB shorting to ground issue.
At this point, I’m grasping at straws, but I think there has to be something there.
This also seems to be reinforced by the fact that my table works so much BETTER than it has previously with the USB port now isolated from the electronics enclosure, but there is still an issue with the USB, in my opinion.
