Install my printer, have a message about USB port MALFUNCTION in my printer BROTHER DCP7020 laser


Hello, Jorge.

It would help to know "exactly" what the error message states, such as "The USB Device Not Recognized" or something like that. Here are a couple of things to try in order to narrow down the problem source:
1. Try a different USB connection on the computer. If that one works, the problem is probably that other connection port.
2. If none of the ports work with the printer, try a different USB-powered device, such as a cell phone and charging cable. If it works, the problem lies with the printer/computer connection (more likely the printer).
3. If none of the USB ports work, the problem might be your USB port itself. Go to "Device Manager" (in Control Panel), then look for "Universal Serial Bus controllers." Check to see if any have a disabled symbol. Check under "Properties" that device status is: "This device is working properly." If not, try updating the drivers (under the "Driver" tab).

Printer not being recognized by computer


Sir/Madam

1. Is the printer turned on?
Make sure the printer is turned on.
Make sure the power cord is securely plugged into the electrical outlet.
Test the power by plugging in the power cord of another electrical appliance to an electrical outlet and turn it on. If the power to the other electrical appliance comes on, the printer may be considered to be faulty.
If this product is recognized:
Close this page to return to the installation window.
If this product is not recognized:
Proceed to the next step.
2. Are your computer and the printer correctly connected?
Make sure the USB cable is securely connected to the printer and to your computer and check that the USB cable is not damaged nor badly crimped.
The printer will not be recognized during the driver installation if connected to a printer switch or the printer buffer. If this is the case, try to directly connect the printer to your computer using the USB cable.
If you are connecting the printer to your computer via a USB hub, connect the printer to the first-tier hub from your computer. If the printer driver is still not recognized on your computer, try to directly connect the printer to your computer without the USB hub.
If you are connecting the printer to your computer via a USB hub, make sure the USB hub device is recognized by your computer.
If this product is recognized:
Close this page to return to the installation window.
If this product is not recognized:
Proceed to the next step.
3. Does your computer provide USB or IEEE 1394 support?

Having trouble installing HP Photosmart All in One Printer. Model C5280. Near the end of installation it ask's for printer to be connected via USB cable. Msg comes up on screen 'USB Device not recognized'...


Dear Sir:

It seems that the printer has gone bad because when you get this message 'USB Device not recognized' it means that the usb device connected to the computer is defective however I would suggest you to connect this device to another computer and if you are getting the same error with the other computer.

Please contact hp support they should be able to help you with this.

Please feel free to get back to me If you need any further assistance.
Regards
Mohammed.
