User's Guide: USBXchange • 25 Troubleshooting If you have problems with the USBXchange, check these troubleshooting tips: My device is not recognized. How can I get the system to recognize my device? o The USBXchange is designed to receive its power from either the termination power line of the attached SCSI devices or, if not present, from the USB bus. In some cases, especially when using unpowered USB hubs with attached SCSI devices which 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 adapter. See USBXchange Power Supply on page 13 (PC) or USBXchange Power Supply on page 20 (Mac) for more information. o The SCSI devices must be powered on before the system acknowledges the USBXchange. Power on all SCSI devices and plug back into your Macintosh or desktop PC. o Verify that the drivers are installed on your computer. o If you are using a hub, we recommend using self-powered hubs. My SCSI peripheral has a different connector than the one provided on the USBXchange. How can I correct this problem? Check the Adaptec online store for the correct cable. Adaptec provides a wide range of SCSI cable solutions. When I change CDs using Windows, I don't see the new one in the drive. Use the View Menu/Refresh option to refresh your screen.
