People with home brewed machines always have quirky issues.  Most of the time it is related to USB port hardware and drivers, most especially those who are running AMD chipsets.

Canon does not recommend USB port expanders, and discourages their use.  Are there any USB ports, perhaps on the rear, that connect directly to the motherboard?  Did you try one of those?  A recent user found that to be a solution.

The camera responce does not change when i use a rear panel USB port.

The Machine has been working flawlessly with canon software  upto a month ago.
It is 100% sure not the machine.

If you ask me the service canon wrote is outdated by the W10 1909 updates.
Microsoft is a very unreliable partner. Rejecting working drivers or services just to piss us off is unforgivable.
This is not the first package wich collapses under the wild reckless update strategy of W10
Maybe the MOBO needs a software update or maybe i shouldn't have updated the MOBO at all.

The Dell Laptop i use is the same unreliable house of cards as my home brew PC.
on any given day software may stop working because MS decides to stop accepting the drivers.
It happens on a regular base because my job havely leans on USB tools. 

I do understand Canon does not like USB expanders. It is a house of cards. Fitting Displayport into the USB-C protocol does have its risks towards the rest of the lot.
