I have a Canon 7D and 7D MkII and my Dell XPS desktop and laptop will not recognize either of my cameras which are connected with the USB cable. I get the 4 beeps when it's connected but that's all. They both worked fine a couple of months ago, now nothing. I use the laptop for tethered shooting.
My wife's HP desktop and son's old Dell inspiron, both running Win 10, does recognize both.
Can you read the memory card in Windows Explorer?
If you are implying that the EOS Utility does not automatically start, I suggest that you go into the C:\Programs folder and start it up manually after you get the four beeps. I think those two cameras use different versions of the EOS Utility, too. Might have to do it for each camera.

I understand your frustration! I have been to Microsoft with this problem and and had no success. I reckon the problem lies in the Windows updates but of course they won't hear of any such thing. Good luck with it. I was thinking of rolling back the Windows upgrades but this is the only thing that's annoying me, so I'm considering myself lucky.

I'm not implying anything about the EOS utility. I'm saying my computer and software, Lightroom, Windows Explorer and EOS Utility will not recognize either of my cameras. I use my laptop with Lightroom for tether shooting
I can and do use a card reader on my desktop

I was having the same problem on my HP Envy 17 i7 laptop from 2016, but NOT my new Dell g7 17 i7 from 2020.
I would get the 'USB PLUGGED IN' sound (with supplied cable, and 4 other micro usb cables) but nothing would show up on the windows end.
However....when I plugged in my Canon 90d, EOS Utility opened right away and my computer asked me "what to do with 90d", AND it showed up in "This PC"
In device manager I noticed that my 7d mkii was being seen 14 devices down in alphabetical order under "libusb-win32 devices" as "CANON EOS 7D MARK II"
Step1. UNINSTALL THAT DEVICE.
Step 2. Shut off Canon 7d mkii
Step 3. Turn Canon 7d mkii.
You will now again hear the USB Recognized sound.....
AND you should also immediately see the EOS Utility software open up on screen....
As well as be asked by windows what do to with Canon 7d mkii, as well as see the device in "THIS PC"...
And finally, in device manager you will no longer see "libusb-win32 devices", but instead 18 options down in alphabetical order as "portable devices" "CANON EOS 7D MARK II".
In my case, to use the new "Canon webcam utility", you must exit out of "EOS Utility" first, to use your Canon 7d MKII with webcam utility in software such as OBS.
