A Windows dialog box will appear when you have successfully
uninstalled the USBXchange driver:
USBXchange Power Supply
The USBXchange receives its power from either the termination power
line of attached SCSI devices or, if not present, the power is automatically
switched to the USB bus. In some cases, especially when using
unpowered USB hubs and the attached SCSI devices do not supply SCSI
termination power, the USB bus cannot supply the needed power for the
USBXchange to operate. In these cases, you may need an external DC
power supply.
Note:
Adaptec strongly recommends that you plug the USBXchange
directly into a USB port on your system. If you must connect
through a USB hub, use only a self-powered USB hub.
With Windows 98 SE and Windows 2000, you will receive an error
message if the USBXchange is not supplied with enough power to
operate.
Note:
Unlike Windows 98 SE and Windows 2000, Windows 98 does not
provide an applicable error message to notify you of a potential
termination power problem. By following the recommendations
on page 14 however, you should still be able to correct the
problem.
