Canonmax310 works fine but creates new problem. Computer has 4 USB ports that work with all devices until I connect Canonmaxz310 to any one port. The screen reads that Windows does not recognize port when I try to use any other device. Disconnecting Canonmax310 clears all ports. Why would this be happening and what might I do to correct this problem?
Local computer shop employee suggested that the USB ports on the front of the computer might be the problem rather than the printer causing havoc. I connected all devices on the back USB ports and the problem was corrected.

If the USB port was fine, the unit would come on regardless if the battery was good or not. This is telling me your USB port is loose. We fix these all the time.
Most issues causing this is a bad charger, dead battery or caused by a
loose USB port in the back. If the port is loose, the battery will not
be charged and won't even work when connected to an external charger.

Printers are particular about which usb port they are plugged into, a virtual printer port is assigned to USB1 in the computer, when you select the printer port for it to use. You may need to plug the printer into each USB port, until you fine the USB port 1 which it works in, remember to always connect it to this same usb port, otherwise it will not work. There is only one USB port number 1.
I've found the same problem - keyboard, touchpad and mouse buttons not responsive - and was almost ordering a new KB/touchpad replacement, thinking they were bad. I searched the internet and found that people had already done that with negative results. Studying the KB/touchpad circuit board I found that the controller was a USB device. So I had an idea, why not test it using one external USB port. I soldered the proper wires to a USB plug and connected it to a side USB port and, voil?!, it worked. Then, I removed 2 inductors from the original D+ and D- lines to isolate the KB/touchpad connector and soldered 2 pieces of wire to one of the side USB ports - in sequence, I covered that port with a small aluminum plate to avoid it being used for another device. Reassembled the computer and everything is working fine, back to normal (with one less USB port, of course).
Try removing all ports from your laptop, then reboot, and then create just one USB port. Also, go to your hardware devices and make sure your usb ports don't have any question marks or yellow warning symbols. Be sure first that the drivers for your USB ports are installed and working first. This sounds either a faulty USB cord, which does happen, or USB drivers issues in your laptop. The printer is probably not the problem here.
What you want is a USB hub. That will allow you to connect more than two USB devices to your computer. There are two types, USB 2.0 and USB 1.1. USB 1.1 will work for most slow speed devices, USB 2.0 is better for cameras and hard disks that have the support. You should confirm which version of USB your computer has, but you should be OK getting a USB 4-port hub, plugging that into your computer, then plugging your keyboard and mouse into the hub and using the other port for the new peripheral that you wish to install. Old PCI cards are problematic because you need the correct drivers. You also need to make sure you plug them into the proper PCI port. It sounds like the device you got from e-bay might be bad, so you shouldn't continue to use it. If you post the make / model of your computer we might be able to suggest a new PCI card that will work if you still want to add more ports to your computer.
As you stated the device works in one slot but not the other , tells you there is problem with that usb port , don't use those ports , best thing to do is purchase a PCI USB card if you need more USB ports .
