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....
