IF61 Fixed Reader User’s Manual 101
Managing USB Devices
You can connect USB devices such as flash drives or memory sticks to
the IF61 USB ports. By default, the IF61 looks for USB devices
installed in its USB ports and shows the devices in the local file
system.
To manage USB devices
1 From the menu, click Maintenance > USB. The USB screen
appears.
The Enable External USB check box is checked by default. When
external USB is enabled, the IF61 looks for upgrade files on USB
devices and automatically loads the upgrade files if found. For
more information, see “Upgrading With a USB Drive” on
page 112.
The External USB High-Speed Mode check box enables the IF61 to
communicate with USB devices at USB 2.0 speeds. If you
experience problems with externally-connected USB devices,
uncheck this box.
2 To disable automatic upgrades, uncheck the Enable External
USB check box.
If you made changes to files in the /home/developer/usb1
directory on the IF61, click Sync File Systems to copy the files to
the USB device.
