The USB 2.0 active extension cable can be used to extend the cable length of any USB 2.0 device. The extension acts as a transparent hub and buffers all upstream and downstream traffic. This is to ensure that the signal meets the electrical and timing specifications. Using passive extension cables can result in timing errors and data loss.
