Troubleshooting

Hubs

The following figure shows the recommended configuration for

connecting USB 1.1 and USB 2.0 devices. Note that you could

connect USB 2.0 devices to a USB 1.1 hub, but the USB 2.0 devices

would run at slower USB 1.1 speeds.

Troubleshooting

If you encounter difficulties installing or using your USB2connect

adapter, check the following:

■ Is the card seated evenly in the PCI slot?

■ Did the driver fail to load? If so, try moving the card to a

different PCI slot.

■ Is bus mastering support provided and enabled for the PCI slot

containing USB2connect? Check your motherboard

documentation for information.

■ Did you encounter problems with a USB device when it is

connected to a hub? If so, connect the affected device directly to

the USB2connect adapter.

■ AUA-5100 only—Did you attach a device to a disabled

connector? See Installing Jumpers – AUA-5100 only on page 3 for

details on enabling and disabling connectors.

■ Did you encounter problems loading the drivers on your

Windows 2000 operating system? If so, refer to the

Readme file

on the USB2connect CD. Also, check the Windows 2000 event

log and the troubleshooting section of your operating system

user’s guide.
