6.1. User Advice When Using USB 2.0
The following technical information relates to your LaCie Dupli Disc CD121 and gives some practical advice:
6.1.1. USB 2.0 Host Bus Adapters and Performance
To utilize the newly-enhanced USB 2.0 performances, your computer must be equipped with a USB 2.0 host bus adapter card
(sold separately, such as the LaCie USB 2.0 PCI Card, or integrated by your PC manufacturer) and the appropriate drivers.
These host bus adapter cards, which include one or more USB ports, are shipped with special USB 2.0 drivers that enable the
computer to control the card. These drivers must be installed in order for USB 2.0 devices connected to the port to work at
their correct speeds. For installation instructions, please refer to the documentation that comes with the host adapter card.
LaCie supplies only the appropriate USB 2.0 drivers for its peripherals and does not provide drivers for third-party host
adapter cards. To obtain the right drivers for your host adapter card, visit your card manufacturer’s Internet site.
6.1.2. Data Transfers
During data transfers, it’s best to wait before launching other applications on the same USB port. Anomalies may arise with
computers that have USB controllers that do not conform to OHCI (Open Host Controller Interface) standards. Your product
has been tested and checked on computers with Intel USB platforms. In any other configurations, we cannot ensure 100%
correct operation. Due to this, you may encounter hanging problems. If this happens, proceed as follows:
1) Make sure that the USB cable is connected tightly and securely on both ends of the cable, from the drive to the computer. If
you are using a USB cable other than the one supplied with your LaCie drive, check that your USB cable is properly certified.
The cable that is provided with your LaCie drive is USB certified.
2) Check that the power supply and ground are seated properly.
3) Disconnect your computer’s USB cable. Wait 30 seconds and reconnect it.
4) Check the Windows 98 SE version installed on your computer. Supported versions of Windows 98 SE are 4.10.2222A
and above. To check the version number, you need to execute the program
Systems
.
5) To proceed, launch the following command from the Windows
Task Bar
:
Start
>
Settings
>
Control Panel
>
System
.
If your USB drive is still not recognized or if you encounter any difficulties, check the type of USB controller available in your
computer. You can access it from the
Task Bar
of Windows. Proceed as follows:
