I was trying to troubleshoot my can adapter which has not worked since I bought it, I am using it with 2 Odrive S1 units. The adapter wont show up in device manager, I am extremely confused with this.
Hi! Do the LEDs on the CAN adapter come on when you plug it in?
Yes, but no flashing
That’s fine – that just means uninitialized. Do you have a different USB cable and/or computer to test with?
In case this is an issue with the USB connector, I’d be happy to toss another unit in the mail for you; if you wouldn’t mind, could you shoot an email to info@odriverobotics.com with your original order number and best shipping address, referencing this thread?
I did try many cables ( i test every cable, and i throw out every power-only cable) and 3 computers, I can reach out via email. Would you like me to ship the one I have back for inspection?
The new adapter won’t connect to the odrives, it is giving errors like memory out of bounds, cannot claim port, am I doing something wrong? I am on a windows 11 laptop, I tried the USB-C port and USB-A ports. The adapter shows up in device manager, but the web gui won’t recognize it.
Can you show the driver that’s set in device manager? Also, would you mind collecting the data as shown here? Web GUI — ODrive Documentation 0.6.12 documentation
Sorry for the delayed response, had some family stuff, here is the files, I have the odrive powered, with the can bus plugged in with a known good cable

Thanks!
Can you try this exact sequence:
- Unplug the adapter
- Refresh the GUI page
- Plug the adapter back in
- Wait a few seconds, and it should show up in the GUI’s device list on its own. Connect from there.
Don’t go through the browser’s “pair device” popup this time, that’s only needed the very first time an adapter is used.
Let me know how that goes!
The odrives still do not show up via Can bus, even with that sequence
Im considering having an isolated USB hub and connect via usb, would that be a better idea? My goal is to have both odrives showing up on my computer at once for easy programing.
If you put both ODrives on their own isolators, that should be just fine.
That being said, CAN is still recommended – seems like some really bizarre quirk of your system though. Would you mind sharing what computer model this is?
One last thing to try – in case for some reason a really weird driver got set, you could try uninstalling the driver for the USB-CAN adapter, then plugging it in again, which should force a refresh of the driver used:
