2.0 Driver Limitations:
=======================
The following USB 2.0 devices and features are not supported
in this driver release:

1. No Hi-Speed Isochronous Support

2. USB Composite Devices

===================================================
2.0.1 Includes support and fixes for the following:
===================================================
1. Power management support for:
Improved stability and functionality in Windows 98 SE, ME, 2000, 
and XP hibernate and sleep modes

2. Playback of Video Compact Discs (VCDs)

3. USB 2.0 Cameras that use bulk transfers

4. Fixed problems with handling of short packets during transfers

=========================
2.1 Troubleshooting Info:
=========================
1. When using Windows ME, the Device Manager will have a green
   question mark next to any USB 2.0 device which is connected
   to a USB 2.0 card. The device will continue to
   function properly. This is an operating system feature.

2. When using Windows 98SE, if the system attempts to enter
   in-active standby (S3 mode), the driver will only allow it to
   enter standby (S1 mode).

3. When doing a hot-unplug/hot-plug, the system may not recognize
   the USB 2.0 device.  To workaround this issue, allow at
   least 3 seconds between a hot-unplug and hot-plug.

4. When using Windows 2000 and XP, if two or more USB 2.0 devices are
   disconnected using the "unplug or eject hardware" icon in the
   system tray without physically removing the device, then when
   one of the USB 2.0 devices is physically removed, the other
   USB 2.0 device will re-enumerate.  To workaround this issue,
   hot-unplug each USB device you want to remove before using
   the "unplug or eject hardware" icon to remove the next USB
   device.

5. When using Windows 2000 and XP, with certain CD-RW applications
   running, the system may stall if an USB CD-RW drive is
   removed using the "unplug or eject hardware" icon in the
   system tray.
   
6. When using Windows 98SE, Windows ME, Windows 2000 and Windows XP,
   the system may not behave properly should it attempt to
   enter active-standby (S3 mode).
