==========
3.1 Notes:
==========
- Do not attempt to put the system into standby or hibernation
during data transfer (I/O activity) to a USB device.
- The first time a USB device is plugged into a USB port, the
system may prompt you to locate the driver for that USB
device and request a restart.
- Do not add or remove USB devices while the system is in standby
or hibernation.
- USB devices that do not work well when attached to USB 1.1 hubs
will also not work well when attached to an Adaptec USB 2.0 hub.
- Please check your device manufacturer's web site for the latest
updates to their software.
=========================
3.2 Troubleshooting Info:
=========================
- If you attempt to put the system into standby or hibernation
during data transfer (I/O activity) to a USB device, you may
experience problems with your system. Please do not attempt to
put the system into standby or hibernation during I/O activity
with a USB device.
- When using Windows Me, the Device Manager may have a green
question mark next to a USB 2.0 storage device which is
connected to an Adaptec USB 2.0 card. The device will continue
to function properly.
- When using Windows 98SE, the Adaptec USB 2.0 driver may prevent
some systems from entering into standby mode.
- The system may report that a USB 2.0 CD-RW connected to an
Adaptec AUA-2000LP card does not contain any media when
resuming from a suspend. To work around this issue, use the
"unplug or eject hardware" icon in the system to remove the
USB 2.0 CD-RW. Unplug the USB 2.0 CD-RW from the card, and
then plug it back in.
- If you unplug/re-plug a device too quickly, the system may
not recognize the USB device. To work around this issue, allow
at least 3 seconds between a unplug and re-plug.
- Removing two or more devices using the "unplug or eject"
hardware icon (on the system tray): Use the "unplug or eject"
icon to remove one device, then physically remove the device,
before attempting to use the "unplug or eject" icon to remove
other devices. If you attempt to remove more than one device
using the "unplug or eject icon," physically removing a USB
device may cause the other devices to re-enumerate.
- When using Windows 2000, with certain CD-RW applications
running, the system may stall if a USB CD-RW drive is
removed using the "unplug or eject hardware" icon in the
system tray.
- Before making any changes through the device manager to enable
or disable the Adaptec Enhanced Host Controller, stop all USB
devices connected to the Adaptec host bus adapter or CardBus and
remove the USB devices from the system.
- When using an HP PSC-750 printer/scanner/copier or a Tascam
USB-428 audio/MIDI interface, we recommend connecting the device
directly to your USB card or built-in USB port rather than
through a Hub.
- When using the Adaptec AUA-1420 CardBus card and the Xircom
Ethernet CardBus card, the Xircom CardBus card must be inserted
first. When booting remove the Adaptec AUA-1420 CardBus card
until Windows is fully booted, then insert the AUA-1420 CardBus
card. Inserting the Xircom Ethernet CardBus card after the
Adaptec AUA-1420 CardBus will result in a System hang or an
unexpected reboot. The laptop will not boot if both cards are
installed at startup.
- Before removing an Adaptec AUA-1420 cardbus card, use the
"unplug or eject" icon (on the system tray) to stop and remove
attached USB devices. Then use the "unplug or eject" icon to stop
the "NEC USB Open Host Controller". It is then safe to eject the
Adaptec AUA-1420 from the cardbus slot.
- When entering standby, in-active standby, or hibernate mode with
a USB 2.0 isochronous device connected to a USB 2.0 PCI adapter or
Cardbus card, the device may not function properly. To work around
this issue, unplug and re-plug the device to the USB port.
- When using a USB 2.0 Cardbus card in a PC laptop system for the
first time, make sure that the card is installed in the system
before booting so that the Adaptec USB 2.0 drivers load properly.
- When using some USB 1.1 audio devices, there may be problems when
they are connected to the system via a USB 2.0 hub. To work around
this issue, unplug the device and plug it back in to a different
hub port or plug the device directly into the USB controller.
- When using Windows ME on a PC laptop system, the USB2.0 Cardbus card
may not show up in the Windows Device Manager after waking up from a
hibernate mode. To work around this issue, unplug the Cardbus card
and then plug it back in. The card and all attached devices will
show up in the Device Manager.
- When using more than one USB 1.1 camera device connected to an
Adaptec USB2.0 hub, the preview windows may not show up for all
devices. To work around this issue, connect a maximum of one device
to the hub and the rest of the devices directly to the USB 2.0
controller card.
- When using Windows ME on a Sony Vaio J200 desktop system, there may
be problems using an Adaptec USB 2.0 hub. To work around any
problems, do not connect a USB2 hub to this system configuration and
connect all USB devices directly to the USB controller card.
