Usb ports do not recognize peripheral devices such as printers or memory sticks.

    Hi yes! Today had 4 power failures. I use a laptop with 2 4 port usb hubs; but it seems that the ports itself is the problem. When pluggin in the hubs or my mobile usb cable directly to the ports it gets power but no recognition. A memory stick or my USB external drives - no luck at all. I have uninstalled drivers, rebooted, etc.

    Do not know what to try next and this is my income generator that we are talking about - I am a Virtual Assistant

Even usb devices have to have drivers installed. Most printers and the like should be installed before you plug them in or it gives the os problems

Set-up won't recognize that the USB cable is connected to both printer and computer and therefore printer won't work. What's up with that??


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

I used this memory stick on my old PC at home and it was wrking okay. When i put it into the usb port it showed up ad removable E. Now I have upgraded my pc to a laptop it doesent recognise the stick....


I assume when you say "memory stick" that you mean a USB memory stick rather than a Sony memory stick.

You should try it in another USB port (if ther is one on your laptop). If that doesn't work, then try it in another PC - if it doesn't work in another PC either, then it is likely that the memory device is at fault, otherwise. If it works fine on another PC, then it is likely that it is the USB port on your new laptop that is at fault in some manner.

If you have another USB device you can use (anything will do - a mouse, webcam, etc), try it in the port you tried the memory stick in. If nothing happens, then in all likeleyhood, the USB port is at fault. If the other device works, then it is probably the USB memory device that is faulty.

If the device works in another PC, try reformatting it as FAT file system on that PC, and see if you can then see it in your new laptop.

Try disconnecting all external devices and reboot your laptop.
You must have all USB devices disconnected, memory stick, USB mouse or keyboard, Hard drives, flash cards ect.
After a reboot check your device manager for flags or exclamation marks and remove if present.
Again, re-boot your laptop and check your device manager.
Ounce you have cleared all marks from device manager and all is clear,
plugin your first USB device and check operation.
Please check your equipment manual for details on what USB ports and speeds are available for your required devices.
Hope this works for you.
Please rate ASAP
Thanks

My d610 does not recognize my cd drive


Is the USB-compatible drive recognized when connected to some other computer? If OK, then the drive is OK.

Is _ANY_ USB device (memory-stick, camera, mouse, keyboard, printer) recognized when connected to any of the USB ports on your computer?
If not, then the USB device-drivers for Windows have not been loaded.

Drastic: backup all your data files, bookmarks, and music, to an external hard-drive, and reinstall Windows from the Dell-provided "System Restore" set of CD-ROMs.

Computer won't recognize printer


Try each of the USB ports on your computer.

Assuming that you have a USB-cable between the computer and the printer, unplug the USB-cable from the computer, and connect some other USB device (iPod or memory-stick). Does Windows detect that other device? If not, then you need to install the correct software device-drivers for your USB ports.

Is the printer properly detected when connected to some other laptop/desktop computer?

Try a different USB port on your computer.

The problem is that some usb hub devices are not powered enough to recognise peripherals, i always recommend buying a mains powered usb hub as the pc's supply can find it difficult to power the usb ports enough as well as powering other components in your pc.

Trying to install printer but usb ports are not being recognized. How can i fix this?


go to control panel/system/hardware/device manager

look for the Usb ports at bottom. any of them that are marked with question mark, will need to be uninstalled, then scan for hardware changes(actions)

that should do the trick.

otherwise, you may need new drivers..see here possibly, depending on what printer you have.
