Troubleshooting
If you have problems with the USBConnect 2000 adapter resulting
from errors in preparing and connecting the SCSI devices to it, check
the following troubleshooting
tips.
My device is not recognized. How can I get the system to recognize my
device.
1
The USBConnect 2000 adapter is designed as a self-powered
device and as such receives it’s power from the termination
power line of the attached SCSI devices. As a result, all SCSI
devices must supply termination power. Some devices such as
the Iomega Zip drive and some scanners do not provide termi-
nation power and as such can only be used if they are attached
to the SCSI chain with another SCSI device that provides ter-
mination power.
2
The SCSI devices must be powered on before the system
acknowledges the USBConnect 2000 adapter. Power on all
SCSI devices and plug back into your Macintosh or desktop
PC.
3
If you are using a hub, we recommend using powered hubs.
My SCSI peripheral has a different connector than the one provided on
the USBConnect 2000 adapter. How can I correct this problem?
Check the Adaptec online store for the correct cable. Adaptec pro-
vides a wide range of SCSI cable solutions.
The USBConnect 2000 adapter size makes it difficult to daisy chain my
SCSI peripherals. How can I correct this problem?
1
Try changing the order of your SCSI peripherals to determine if
one has more working space around the connectors.
2
Try attaching the USBConnect 2000 adapter to an external SCSI
cable and then attaching the cable to the device. This
prevents the USBConnect 2000 adapter from competing for
space on your SCSI device.
