I have a 128 MB USB 2.0 Drive.
When i plug into my Computer i get the message.

The "Pine" is High Speed Device USB Device and will function at a reduced speed when plugged into a non High Speed Port.

There are no High Speed USB Conrollers installed on this computer ?

Recommendtaion
The Pine USB Drive will function at a reduced speed. You must add a High Speed USB Host Controller to this computer to obtain maximum performance.

----------------------------------------------------------------------------------------------------------------I am using windows XP Home Edition and would like to know how can i install High Speed USB Controllers to my Windows XP.

Thanks in advance.

It may just be a case of installing newer drivers for your usb, providing it is capable of supporting the usb 2.0 standard.  USB 2.0 support was added in XP service pack 1.  You can get the servicepack by going to www.windowsupdate.com.

If for some reason your USB ports are not capable of supporting 2.0 (older chipset), sunray_2003's suggestion of adding a PCI card that supports it is good, and newegg sells combination USB/Firewire cards for relatively cheap ($30): http://secure.newegg.com/app/specification.asp?item=15-102-003

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You may not have USB 2.0 ports on your mainboard as standard - you can check this by going to device manager (right click My Computer > Hardware tab) and clicking the + next to Universal Serial Bus Controllers. You may also potentially need a chipset update for your particular USB chipset http://www.usbman.com is useful for such matters

If you're running Windows XP you'll need Service Pack 1 to support USB 2.0 but I suspect you problem is a lack of USB 2.0 hardware on your mainboard in which case you will need a PCI to USB 2.0 card.
