First to have USB2.0 (Hi-Speed) capable hardware. Only in Windows XP Service Pack 1 (SP1) USB2.0 is not supported and USB2.0 drivers have to be installed manually.
To know is you have USB2.0 drivers & hardware:
In Window XP:"Right click my computer, then "manage", select device manager and scroll down to USB controllers. Click the + then look for the word "Enhanced" in either of the host controller listed. If there's 1 with Enhanced, then you have USB2.0 capable hardware.
See the related link for more info about USB1.1 and USB2.0
A USB host controller is a piece of hardware. It is usually incorporated into the southbridge in your motherboard. As such, it cannot be downloaded. If you want to upgrade a low-speed USB controller to a high speed controller you will have to buy a new high-speed controller. Changes are the old controller is not removeable and not upgradeable.
If you're using older drivers you won't be able to use high speed. Check to see if there are newer drivers available for your USB ports.
you go to your motherboard manufacturer's website and download the propper usb controller for your board.
You can download a driver for a hi-speed USB controller that is already installed. You cannot, however, download any software to make an older USB controller faster.
Host controllers can NOT be downloaded. A host controller for hardware is always going to be a peice of hardware. in your situation, you probably don't have a USB2.0 high speed port. You can always get a USB2.0 PCI adapter.
USB 2.0
NO, because a high speed USB only capable on a 480 and 12 mbits/second while your non hi speed port is only 1.5 mbits/second. but you can use a USB 2.0 because it is capable on a 480, 12 and 1.5 mbits/sec. ok
A high-speed USB (2.0) has a raw data rate at 480Mbps, and it is rated 40 times faster than 1.1.
If you have Windows XP Service Pack 1 (SP1) then you can add USB 2.0 drivers to enable the USB host controller to operate at USB2.0 speeds. Windows XP Service Pack 1 is released with USB1.1 (slow) host controller device drivers. From SP2 and onwards USB2.0 is supported by default. See the related link for more info about why USB 2.0 operate at USB 1.1 (slow) speed.
High Speed usb is 2.0 now some comptuer have a 2.0 speed usb port some are slower. So if it says "You have plugged in a highspeed usb to a slower port" Or w/e then that means it will just be slower. Newer / Old but expensive comptuers have high speed USB ports. Hope this helped
If the controller plugs into a USB port, yes.
Hint hint... high speed
