USB none of the usb ports on my ze2000 detect anything i plug into them...i looked to see if they were functional in my control panel and it said they were fine...any tips on fixing USB port/ detection? my usb ports will not recognize anything i plug into the ports... including an external hard drive, ipod connection cord, wireless mouse, etc... sometimes when i plug it in to the computer, it will read the usb for about 5 minutes and then i get a message that says "this usb device can perform faster if you connect it to a hi-speed usb 2.0 port." but it doesnt work in any of my 4 usb ports... what should i do?

First of all, I recommend you to Uninstall the USB Devices from the Device Manager and reinstall the Chipset Drivers as per the instructions below :
Click on Start and then on Run.
Type devmgmt.msc in the Run Command box and click on OK.
This will open the Device Manager window.
In this, click on the + mark next to Universal Serial Bus Controllers which will display additional USB Entries.
Right click on each of the entry and select Uninstall.
Click on OK if you get any confirmation window. Repeate the same process untill there are no entries left under Universal Serial Bus Controllers in the Device Manager window.
We are done with uninstalling the USB Drivers from the Notebook.

Now, restart the Notebook and close any window which says 'Found new hardware'

Now, download and install the Chipset Driver in your Notebook from the link below :
http://downloadmirror.intel.com/8178/a08/infinst_autol.exe

Save the file in the Notebook and double click to install the Chipset Drivers.
However, if the issue with the USB Ports persists, I recommend you to check again with different devices to confirm if the issue is with the USB Ports of the Notebook itself.
If the Notebook doesnot recognize any of the USB Devices after installing the Chipset Drivers, you may need to get the USB Ports of the Notebook replaced or go with a PCMCIA USB Card.
Hope this helps....

Why won't the right USB port recognize when I plug in my mouse?


Your USB ports on your computer are plug and play. If you have issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.
To Identify a Working USB Port
Begin troubleshooting your USB ports by checking Device Manager to see if your USB ports or hubs are working properly.
  1. Click the Start button. ClickControl Panel.
  2. ClickSystem and Maintenance.
  3. ClickDevice Manager.
  4. Double-clickUniversal Serial Bus controllersand check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
  5. If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.

To Update the USB Port Driver

An out-of-date BIOS driver can create issues with your system recognizing the USB port.
  • Watch a Video on Steps to Update Bios on Your Computer.
    1. When the update process is complete, your computer will restart again to load the operating system with the new driver version installed.

Usb ports not recognized


Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.

USB not working


if the usb detects other devices and not your drive,the drive itself may be faulty.If you plug in other devices in the usb and it detects them the usb drive or its connector is most likely bad.If it won't detect any devices the port is bad and drivers won't help.Possibly a motherboard issue.

My Panasonic CF-74 doesn't seem to be detecting anything I am plugging into the USB ports or the COM port.


Some motherboard BIOS's allow you to specify how many USB ports you want enabled
go to your Control Panel, System, Device Manager.

go down to where it says Universal Serial Bus Controllers, click the + sign,
you will see a list of devices, probably something like this
via rev5 usb host controller
via rev5 usb host controller
usb printing support
usb mass storage controller
usb root hub
usb root hub

right click on the ones that say via or intel or SIS, or ALI, or Standard open host controller, and choose uninstall.

you will be asked if your sure, and you will see some of the USB root hubs disappear.

If you are asked to restart, choose no, and remove the other via/sis/intel/etc open host controller (s) from your system, when they have all been removed restart your computer.

when the computer restarts, it will detect the USB controller and connected devices, reinstall the drivers/software

USB not working


If none of your USB ports work, there could be a problem with your USB controllers. Uninstall the USB controllers via Control Panel - System ... and reboot your laptop. They will reinstall upon bootup. Good luck.

USB ports wont recognize anything I plug in


Are you using XP? If so:
Here is what you can do to refresh the USB ports:
1. Right click MY COMPUTER
2. Select PROPERTIES
3. Select HARDWARE
4. Select DEVICE MANAGER
5. Select UNIVERSAL SERIAL BUS CONTROLLERS
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB device.


If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

USB PORTS


does your usb mem stick have any light indicators? if yes , whenever you put you usb stick, does it light? if it lights are USB ports is still ok,  You just have to reformat or partition you USB stick.
(you can also try other devices like usb mouse or any usb devices that lights up when you connect it)

if there are no lights if you plug, or no indication that a power goes to your stick, its possible that your usb your are busted. if this is the case, if your laptop has a PCMIA slot, you can find a pcmia USB card, if you dont have. your only option is replace the  motherboard.

Thinkpad T20 won't recognize usb port


You can get a PCMCIA adapter with 4 USB v.2.0 slots on eBay. It requires power from the USB port on the laptop, but the pigtail connector is included. Works like a charm! Comes from China just like everything else in this country.

USB


I had a similar problem, with no help from HP support. A USB hard drive would be recognized, and work, but a Sandisk flash drive and a Fujifilm camera would not. All drivers were uninstalled/reinstalled/updated numerous times. HP finally concluded a hardware problem. However, I noticed an updated BIOS on HP's web site to fix "USB problems" with some equipment. I flashed my BIOS with the new version, and USB now works. Some minor glitches, but acceptable..
