Thanks for getting back to us, 98010.

Since you're still having issues with the card reader, I highly recommend contacting our QuickBooks Desktop Team. They can investigate further what's causing the error to appear even if the computer still recognizes the device.

Here's how to get in touch with them:

1. Open QuickBooks.
2. Go to Help, then select QuickBooks Desktop Help.
3. Select Contact Us.
   
4. We’ll provide you a few support options. Select which one is best for you.

You can also refer to the Support hours and types link to contact us at a time convenient to you.

I've also added this article for other troubleshooting steps with connecting your reader: Fix issues with the GoPayment and QuickBooks mobile app card reader.

Let me know how the call goes by leaving a comment below. I'm always around to help you out.
