Dosent recognize the usb port

1. Confirm the USB port on the computer you are connecting your printer to is being recognized by your computer. The easiest way to do this would be to plug a known good USB Memory stick into the USB port you want to use. If you can read the contents of the USB Memory stick then the port should work. Remove the Memory stick, start the printer installation program (Make sure you don't the printer connected), want until the setup program tells you to connect the printer before you attach the Printer's USB cable.
If the printer isn't recognized try a different USB port, when picking a new USB port to try select a higher priority port, for example in increasing priority from, an external USB hub, a powered external hub, a monitor based hub, USB ports on the front of the computer, up to the USB ports at the computer rear. For USB ports on the same circuit select an USB 2.0 before an USB 3.0 port

Usually usb device not recognized is due to damaged usb cable or usb port..use a different usb cable and connect it to your pc, if your usb cable is ok then connect it to a different usb port. if the problem in not with the usb cable or port install driver from the cd you got with camera. if you dont have that cd download driver from the device manufacturer site.

There can be following 3 problems.
1. USB driver on your laptop. If the driver on your laptop is not installed then it won't work. Confirm by putting any other usb peripheral.
2. USB cable is U/S. try change it.
3. Communication port on your mobile is U/S try to attach another mobile through same cable and check. If faulty then you have to replace the connector.

there might be a connection issue here. if it is connected using a usb cable, check if your printer is talking to the computer, that means you will check if the computer can recognize the printer when connected using a cable,
i hope you state the os of your computer, anyways,

if XP click start--control panel--classic view--system--hardware--device manager--universal serial bus controller--look for usb printing support
(if you found it, connection is good)
if it is not there, unplug and replug the usb and try again, try another port on the computer, if still not, try another usb cable, if both usb are not recognized, it might be the port of the printer or computer, ti=o isolate that, try another computer if thats possible.

Make sure that the parallel port is enabled in the bios and is in standard mode.

Try a other usb cable had same problem new cable fixed it of other device

it's not likely the cable went bad.  Do you have more than one USB port you can try? do you have other USB devices to test the port? did you reboot?
