When connecting a USB 2.0 device, Windows displays the following message:
Install a high speed USB host controller
This device will function at reduced speed if you do not have high-speed controller installed on your computer
The mass storage device is a USB broadband device, which operates at a reduced speed if it is connected to a port with reduced flow. There is no USB host controller broadband installed on this computer. You must add a high speed USB host controller on this computer to benefit from increased performance
This message indicates that the USB port on your computer is recognized as a USB 1.0 or 1.1 . However, many devices need to be connected to a high-speed port to work properly.
Identify the type of USB port
First, it is necessary to identify the type of USB port on this machine.
- Open the Control Panel, double-click System, then the Hardware tab click "Device Manager".
- Expand "Serial Bus Controller" (possibly also "USB Root Hub").
- If the words "USB 2.0" or "advanced USB Controller" is specified, then it is USB 2.0. If "USB Standard" is started, then it's USB 1.0 or USB 1.1.
Another solution is to use a software: Everest or SIW:
If it is a USB 2.0, make sure you have installed the latest drivers from the motherboard. Check if a BIOS update is available for your motherboard. Also check if drivers for the chipset on the motherboard are up-to-date. For Windows OS prior to Service Pack 2, there is also a patch to integrate the USB 2.0 support:
Modify parameters of root controller
In the Device Manager, double-click on the "USB Root Hub", and uncheck "Allow the computer to turn off this device to save power"
Using a powered hub
Installing a USB Hub with its own power supply allows you to connect multiple devices with a single cable, but it can also amplify the signal.
Add a USB broadband
If there are low-speed USB ports, it is necessary to buy an additional card with USB 2.0. For laptops PCMCIA cards can be added and for desktop PCs, PCI cards can be added.
