DAT 160 USB
Verifying USB installation for optimum performance Troubleshooting
6.2.2 Ensure that the tape drive is the only device on a
USB hub (Windows)
On some computers multiple physical USB 2.0 ports will be connected to the
same master port, known as a “root hub”. Connecting multiple devices to one
root hub may degrade tape drive performance degradation.
USB Mass Storage devices like DAT tape drives have the lowest priority of all
device types on the USB bus, so devices such as webcams should never be
connected to the same root hub.
To check the devices connected to a root hub:
Ê
Go to Device Manager and select Devices by connection from the View
menu.
Ê
Expand Universal Serial Bus controllers and locate the tape drive.
Ê race the tree of devices back to the USB Root Hub and check that the only
device connected is the tape drive via the HP USB Mass Storage Device.
6.2.3 Ensure that the hp_usbstor driver is being used
(Windows)
The USB DAT drive will work with the Microsoft usbstor driver, however, we
strongly recommend that you use the hp_usbstor driver for improved perfor-
mance.
To check the driver being used:
Ê
Go to Device Manager and select Devices by connection from the View
menu.
Ê Expand Universal Serial Bus controllers and locate the tape drive.
Ê If the tape drive is connected to the HP USB Mass Storage Device, it is
configured correctly.
