The port to which the printer is connected is not supported. Check the port


I'm assuming you are using a USB connection, not a Ethernet connection.

Try a different USB port (preferably in the REAR of the computer, not the front). It's not unusual to have 1 or 2 poorly-performing (low power) ports on a PC; some printers don't like those.

If you have a really old computer, it may have ancient USB type "1" (slow) ports instead of the newer 2.0 or 3.0 USB type. Some printers don't like old USB 1 ports, but it is not supposed to matter.

If all else fails, try another USB cord, or a shorter one. Some printers don't work well with cords longer than 4 feet, and USB cords can go bad.

Or, try the printer on another computer. If the same USB cord works fine there, YOUR computer has the problem (probably a USB port or USB driver issue).

Are you having issues with other USB devices? If so, it may be a Windows driver issue.

Good luck. If no help, post your exact printer model # here, or try contacting Lexmark.com support

Usb port not working


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.

1 usb port on toshiba satellite c660 doesn't recognize mouse


If is just a USB port, then it could be a driver problem, or that USB hub is turn off, or is a fried/bad USB port. Try another USB device on that port too.

I got a new transcend USB jetflash drive 16GB, but my system not showing any response towards it, what shall i do..??? is to download a software for it...??


Flash drives do not need a drivers (plug and play). There are several possibilities:

1. Assumptions: USB port error, computer drivers normal, normal flash drive.
Solution: insert a flash drive into another USB port. If the USB port 1 is not detected, insert flash drive into a USB 2, USB 3 or USB 4.
2. Assumption: normal USB ports, computer driver error, a normal flash drive
Solution: reinstall the chipset drivers, or USB.
3. Assumption: normal USB port,
computer driver normal, flash drive is broken
Solution: try to insert the flash drive into another computer. If the flash drive is not detected, it means your flash drive is damaged.

Solution to determine the cause of damage:
1. If you have a USB mouse, use the mouse to check the damage to the USB port. Example: connect the mouse to the USB 1, USB 2, USB 3 or USB 4. If every USB port, mouse is detected, the conclusion normal USB port
2. To check your computer's drivers, right-click My Computer - Properties - Hardware - Device Manager

3. If points 1 and 2 are normal, the possibility of flash drive damaged.
Because the new flash drive, flash drive is most likely normal. Based on experience, cause damage to the flash drive is a USB port is dirty. The USB port is dirty, can cause short-circuit flash drive. The characteristics of short-circuit flash drive. When inserted into a USB flash drive (about 5 seconds), the temperature of the flash drive become extremely hot. If there are problems like this, immediately unplug the flash drive, to prevent permanent damage.

I hope this information helps.

I have (2) 1.1 USB ports that says they do not reconise the divice when i plug a divice in , and (1) 2.0 USB port that does nothing but when i go into device managment and check the USB controllers it...


I would suggest two things:

1) Get a different USB device and make sure it works in the ports.

2) Make sure the USB device you want to use is recongnized on another computer. (If possible)

If you have the Vista OS that came on a USB then it is not designed to work on 1.1 USB ports but it should work on the 2.0 port.

My netgear wireless-n150 USB adapter wna1100 can't detect adapter.


First determine that the USB port isn't dead. Do other things work in that USB port? If the answer is yes we know it's not the port. Have you tried another USP port? If it doesn't work in another port (or on another computer's USB port) then it's the adapter itself.

Adapters can go bad. USB ports usually work and don't go out. The exception is that many laptops that come with several USB ports sometimes have one (or more) that never did work.

Try it on another computer. This is one last step to determine if the adapter itself is dead and that it isn't something on/with your computer.

It also could be that the computer has the old USB 1 port and the adapter needs USB 2. (USB 1 was slower).

Why don't my USB ports on my monitor work


1) good USB cable from Monitor USB input port to PC USB port?

2) Check pin 1 of the USB port, you should have 5vdc.

3) Your monitor's USB ports are basically the powered USB hub, but it must be connected to the PC USB port.

ASUS P4SDX USB Ports not recognized as USB2 HS Ports


The message comes up when a USB 2 device is connected to a slower USB 1 or 1.1 port. It is only to advise you that the devise will operate faster on a USB 2 port. If your computer has only USB 1 or 1.1 ports, you will always see the message. You can buy and install a card with USB 2 ports and install it. It will come with the USB 2 drivers. Install the card and the drivers and then connect your USB 2 device to the new hardware and you should not see the message anymore.

Good luck, And let me know ho it works out for you.
