Fundamentals | File management
If an error message is displayed when connecting a
USB device, check the setting in the SELinux security
software.

Page 426
If the control displays the USB: TNC does not support
device error message when using a USB hub, ignore and
acknowledge the message with the CE key.
If the control repeatedly fails to correctly detect a USB
device with the FAT/VFAT or exFAT file system, connect
another device to check the port. If this resolves the
problem, use the properly working device.
Working with USB devices
Refer to your machine manual.
Your machine tool builder can assign permanent names
for USB devices.
The USB devices appear as separate drives in the directory tree, so
you can use the file management functions described in the earlier
chapters.
If a larger file is transferred to a USB device in the file manager,
the control displays a dialog Write access on USB device until file
transfer is completed. The dialog is closed with the HIDE soft key
and file transfer is continued in the background. The control displays
a warning until file transfer is completed.
Removing USB devices
To remove a USB device, proceed as follows:
Move the cursor to the left-hand window
Press the MORE FUNCTIONS soft key
Remove the USB device
