Page 6: Introducing The Usb-2020
The USB-2020 is compatible with both USB 1.1 and USB 2.0 ports. The speed of the device may be limited when using a USB 1.1 port due to the difference in transfer rates on the USB 1.1 versions of the protocol (low- speed and full-speed). -

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the USB-2020 from its packaging, ground yourself using a wrist strap or by simply touching the computer chassis or other grounded object to eliminate any stored static charge. -
