Specs: Windows 10
For several years have had an acer desktop/Windows 10 with HP Officejet Pro 8620. Suddenly I can't send/receive faxes. Troubleshooter "USB Composit device might not work with USB 3.0" What does this mean?

Did you make any changes to your hardware or settings. Did you update any drivers or software for the Officejet? Is your Officejet connected using USB? If so, did you move the cable to a different port?

✔ Best Answer
Yeah, if you have a USB 2.0 port try plugging it in there. The message is about a possible conflict between what windows sees as an older device and USB 3.0. Also check the HP support site for a possible driver update.
