EOS R not detected by PC via USB

[dhammab]

Hello,

I've been trying to set up my camera for tethering, but when it's plugged into my PC (a windows 11 machine), via either a usb-c cable or a usb-c -> usb-3 cable, the camera doesn't even show up in the device manager. Usually in a situation like this I'd download a driver, but there are none available as far as I can tell. Needless to say, the camera also doesn't show up in either EOS Utility or Capture One. 

I've tried disconnected, reconnecting, restarting both the camera and the pc. Have tried it with the memory card both in and out of the camera. Have tried different USB ports. I'm using a direct connection to the PC. 

Any ideas what could be going wrong? I have a number of paid gigs coming up and need to be able to tether.

UPDATE:

After trying another usb-c cable, it immediately detected the camera. I have a feeling this may be related to power draw as someone posted below. Thank you for your help and advice, everyone. Gonna go pick up a new 15' cable and hope that's the end of this particular headache!

Hi, and welcome to the forum.

Can you please advise if you have successfully used this particular USB cable to tether before?

Is WiFi turned off?

I've used both of these USB cables and ports successfully, as of a couple of weeks ago.

I've tried with wifi turned both on and off.

Do you have access to a different computer or camera that would use the same cables? That would eliminate one variable. 

I had some strange (but different) behavior with my 1D X III that I resolved by removing the battery and actuating the shutter a few times to drain any charge. Put the battery back in and problem gone. May not work for you but free to try. 

You could also clear all camera settings.

What did you use the cables to do?  Did you use the cables to connect a Canon cameras to your Windows 11 PC?  

Is your Windows 11 PC based on an Intel chipset?  What brand is it?

I'm using a dell xps 7590 with an intel i7 chipset. I used these cables and ports to tether with my fujifilm gear just a couple of weeks ago without issue.

Can you try your Fuji today?

I sold my fuji kit for this EOS R, haha.
