Adaptec USBConnect2000 User Manual page 17

When I change CDs I don't see the new one in the drive.
Use the View Menu/Refresh option to refresh your screen.
When I power off/on my SCSI device while still connected to
USBConnect 2000 adapter, the system does not detect the
USBConnect 2000 adapter or the SCSI device appears to be missing.
How can I correct this problem?
Try instead one of the following steps:
1
Remove and reinsert the USBConnect 2000 adapter from the
USB port.
2
Remove the USBConnect 2000 adapter, power off and on the
SCSI devices and reinsert the USBConnect 2000 adapter.
3
Remove and the reattach the USBConnect 2000 adapter from
the SCSI device.
4
Restart the system with the USBConnect 2000 adapter attached
and the SCSI devices powered on.
5
Shut down the system, remove the USBConnect 2000 adapter,
power off and on all SCSI devices and reinsert the USBConnect
2000 adapter.
