Verifying USB Installation for Optimum Performance 5

• Ensure that the tape drive is the only device on a USB hub
• Ensure that the Qtmusbmsc driver is being used
Check for USB 2.0 Port (Windows)

It is important to ensure that you connect your drive to a USB 2.0 port.
The drive will work on a USB 1.1 port but performance will be severely
degraded.
To check the port on a Windows system:
1 Go to Device Manager and select Devices by connection from the
View menu.
2 Expand Universal Serial Bus controllers and locate the tape drive.
3 If a USB driver is listed as Enhanced, the port is USB 2.0 (see
