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
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.
USB 2.0
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.
A high-speed USB (2.0) has a raw data rate at 480Mbps, and it is rated 40 times faster than 1.1.
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
Hint hint... high speed
It is USB 2.0, the standard external data and power connection.
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.
12 Mbps for original and 480 Mbps for high speed.Darryl Erickson
Super Speed USB is faster and is usually identified by a blue port or wire. Basically USB 2.0 is High Speed (480Mbps) and USB 3.0 Super Speed (5Gbps).
Up to 480Mbits/second, and being increased over time with improvements.
