I cannot support other USB devices when the printer is plugged in
My computer was giving me an error message on my USB devices. I went into Dell Computer troubleshooting and they said try unplugging other devices that might be draining the computer. When I unplugged the printer the other device worked. I still have the keyboard plugged in with no problem. This just started happening. We have enjoyed the printer with no other problems for almost a year. It is so much better than HP, which we have had for years. I wish I had tried a Canon before.
I hope you can solve this problem. The computer says I would need an external USB Device. But I have had this computer for 4 years with no problems of this sort before. Thanks!

The driver for the canon printer may have corrupted. Unplug the printer. Uninstalled all existence of the canon printer driver. Restart you computer. Turn on the printer and then plug the USB cable to the computer. The drivers will get installed automatically and your printer will work fine.

While at this message remove any USB storage devices plugged into the computer (Cell phones, USB thumb drives, external hard drives) also eject any CDs and Floppies. Turn the computer off and back on. If the issue persists then it is possible that the power failure damaged a physical component of the computer.
This is because you are plugging in a USB 2 device to a standard USB port, or a USB 3 device into a USB 2 port. The computer is just telling you that if you upgrade the hardware, the device will work faster. Its more of an information message than an error. Your device should still function fine.
The USB device could be drawing more current than the USB port can supply or the USB port may be faulty.
Get a powered USB hub and plug it into your computer's USB port and then plug the USB devices into the powered USB hub.
