  under Windows 2000 and Windows XP.





Known Issues

============

- Do not attempt to put the system into standby or hibernation mode

  during data transfer (I/O activity) to a USB device.



- Do not add or remove USB devices while the system is in standby or

  hibernation mode.



- 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 reboot



- 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.



- The Buslink USB 1.1 hard disk drive may not work properly when connected

  to an Adaptec USB 2.0 controller or hub. To work around this issue,

  connect the Buslink USB 1.1 hard disk drive directly into the system. Please

  check the manufacture's Web site for software updates.



- The iBot2 USB 2.0 camera may not work correctly on some systems

  when plugged into an Adaptec USB 2.0 card or hub. To work around

  this issue, plug the camera into a USB 1.1 port. Please check the

  manufacture's Web site for software updates.




Troubleshooting Info:

=====================

- If you attempt to put the system into standby or hibernation mode

  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. There is no problem with the

  device. It 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 tray 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.



- Remove only one device at a time usig the "Unplug or eject" icon on

  your system tray. If you attempt to remove more than one device at

  a time, physically removing one 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 enabling or disabling the Adaptec Enhanced Host Controller

  in the Device Manager, stop all USB devices connected to the Adaptec

  host bus adapter or CardBus and remove the USB devices from the

  system.



- When you are using an HP PSC-750 printer/scanner/copier or a Tascam

  USB-428 audio/MIDI interface, Adaptec recommends that you connect the

  device directly to your USB card or built-in USB port rather than through

  a hub.



- If you are using an Adaptec AUA-1420 CardBus card and a Xircom

  Ethernet CardBus card, install the Xircom CardBus card first, let Windows

  boot up, then install the AUA-1420 CardBus card. Your computer will not

  boot up if both cards are installed at startup, and your system will hang

  or reboot unexpectedly if you install the AUA-1420 card first.



- 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.



- If you have a USB 2.0 isochronous device connected to a USB 2.0

  PCI adapter or CardBus card, your device may not function properly

  when entering standby, in-active standy, or hibernate mode. To work

  around this issue, unplug your device, then re-plug it into the USB

  port.



- When using a USB 2.0 CardBus card in a PC laptop system for the

  first time, install the card before booting up so that the Adaptec USB 2.0

  drivers load properly.



- Some USB 1.1 audio devices, may experience problems when they

  are connected to the system through 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 Windows Me on a Sony Vaio J200 desktop system, there may

  be problems using an Adaptec USB 2.0 hub.  Adaptec recommends that

  you do not connect a USB 2.0 hub to this system configuration and that

  you connect all USB devices directly to the USB controller card.



- Unplugging a webcam while streaming video may cause the system to

  behave incorrectly. To work around this issue, always stop streaming and

  close any preview or capture application before unplugging the webcam.



- When connected to an Adaptec USB 2.0 hub, some USB 1.1 keyboards

  and mice when may not work correctly if a USB camera is present on the

  hub  and is streaming video. To work around this issue, connect the mouse

  or keyboard directly to the USB card or system.


- Some Iomega USB 1.1 zip drives may prevent the system from going into
  or waking up from suspend mode if the zip drive is connected to an Adaptec
  USB 2.0 controller. To work around this issue, stop the drive and unplug it
  before letting the system go into suspend. Please check the manufacturer's
  Web site for their latest software updates.
