USB2connect User's Guide
USB2connect Driver Information
USB2connect is a multifunction device. It has two OHCI (USB 1.1)
controllers and one EHCI (USB 2.0) controller built-in. Because it
has three functions, you will see three instances of drivers for the
USB2connect in the Windows Device Manager after the card and
drivers are installed.
Notes on using the USB2connect adapter:
Windows 98 Second Edition (SE) operating systems require
I
three device driver installations using the Add New Hardware
Wizard. See the Windows 98 SE section later in this guide for
detailed instructions.
Windows 98 SE users might have to install drivers from the
I
operating system CD. All other supported operating systems
should have compatible embedded drivers.
USB2connect does not support Deep Sleep on Power
I
Macintosh G4 systems. The Deep Sleep feature is disabled
when you install the USB2connect driver. If the driver is not
installed on Power Macintosh G4s, you may experience USB
devices disappearing from the bus or the system hanging
when awakened from Deep Sleep.
At the time this guide was written, there were no 2.0 drivers
I
for USB 2.0 devices. Therefore you will see a yellow ! before the
PCI Universal Serial Bus section in the Windows Device
Manager. However, the USB 1.1 drivers included with
Windows are compatible with USB2connect, so you can ignore
the warning. For updated driver information, check the
Adaptec Web site at http://www.adaptec.com.
Without a USB 2.0 driver, USB 2.0 devices will run at USB 1.1
I
speeds even when connected to a USB 2.0 adapter.
USB 2.0 devices will run at USB 1.1 speeds when connected to
I
a USB 1.1 hub.
