It is suitable for remote access, retail and industrial applications, data collection and other applications requiring a High speed and or LOW serial communications port.
In addition, depending on the 2.0 device, it's possible, though not guaranteed, that it'll work just fine with your 1.1 interface. The biggest invisible difference is that a USB 2.0 interface requires different hardware - hardware that is capable of the higher speeds that USB 2.0 supports.
So, to "upgrade" from 1.1 to 2.0 typically isn't a software upgrade at all; it's an addition of hardware.
Once you have the details you can search the USB website for your drivers and, if available, download and install these drivers.
If you are unsure of whether or not you need to update your Drivers, or indeed which Drivers may need to be updated, you can run a Drivers scan using a driver update tool (you will need to pay to register this tool but usually the Drivers scan is free).
You can search for USB 2 Drivers on the manufacturers’ website or use a Driver Update Tool to automate the driver updates.
To fix your Drivers problems you will need to know the particular model of the USB device you are having problems with.
Unfortunately, upgrading from USB 1.1 to 2.0 requires more than software; it actually requires new hardware.
The good news is that the hardware is typically inexpensive. The biggest visible difference between USB 1.1 and 2.0 is that 2.0 is faster.
The USB specifications define how the host PC and USB device communicate with each another.
