Question
Does USB 1.x devices work on USB 2.0?
Answer
Yes, the majority of USB 1.0 or 1.1 devices and hubs are compatible with USB 2.0. However, a USB 1.0 or 1.1 devices are not going to have all of the capabilities and features found USB 2.0. If you are having trouble getting a USB 1.x device working with USB 2.0 it is likely an issue with USB and not a compatibility issue.
In addition a USB 2.0 device will work on a USB 1.1 or 1.0 port unless otherwise stated by the manufacturer of the USB device. It is important to realize that some USB devices not not operate as well in USB 1.x because of the 12Mbps bandwidth.
