Frequently Asked Questions
1. Can I use my DUB-E100 on a USB 1.1 port?
The DUB-E100 will work on a USB 1.1 port but the transfer speeds will be limited to the
limitations of USB 1.1. If your computer does not have USB 2.0 ports, you can purchase an
add-in USB 2.0 PCI adapter to add USB 2.0 functionality to your computer.
D-Link
®
offers the following USB 2.0 adapters:
• DU-520 (5 Port USB 2.0 PCI Adapter) for desktop computers.
• DUB-A2 (2-Port USB 2.0 PCI Adapter) for desktop computers.
• DUB-C2 (2-Port USB 2.0 Cardbus Adapter) for laptops computers.
2. Do I need to use a crossover cable or straight-through cable?
With most of D-Link’s new switches/routers, the Ethernet ports are Auto MDI-II/MDI-X.
This means the port will auto-sense the cable type. Auto MDI-II/MDI-X ports may react
differently if the Ethernet cable is not properly pinned. If you make your own cables, it is
very important that they follow the industry standard pin-out (568A and 568B).
Computer connections to a hub, switch, or router typically use a straight-through cable.
When connecting a computer to another computer or to an uplink port then a cross-over
cable is typically required. Rule of Thumb: ”If there is a link light, the cable is right.”
3. How do I verify that my DUB-E100 is properly installed?
You can verify that the adapter has been properly installed in Device Manager:

• Go to the Device Manager tab.
