I would definitely try other cables, as mentioned, just to rule it out.
Check device manager and see what it's showing up as. If it's under "portable devices" as an mpt device, you're having a similar issue as me. You could try to update the drivers manually, as that seems to have helped some people. There's a YouTube video outlining this process if you search for "canon no connection mtp update". Maybe that will help.
You can also go to start/settings/devices & printers, and see if it shows up as the generic "Canon camera" or of it actually shows the model. That might reveal something to help get you in the right direction.
You can try removing the device by opening start and searching device manager and see if it reinitializes properly once it's removed.
Another thing to make sure of is that you're running the right version of EOS Utility. Version 3 doesn't add a shortcut or start menu item. You have to manually find it in the folder and create a shortcut (Idk why). There are videos for that too! My R won't connect through the older versions that are default.
A wild guess of something that might help if all else fails is to try a USB "on the go" aka USB OTG adapter. Idk why this would help, but neither do I know why thr hub worked for me. Seems altering the USB protocol did something in my case, and might for others such as yourself. Unlikely, but I would have said the same of the usb hub.
