 Precautions for using USB storage

While accessing the USB device, do not reset the display unit or remove the USB storage device.
Data on the USB storage device may be corrupted.
 
To remove the USB storage device safely, design the system to remove the device only after turning ON a system variable "#H_Control_USBDetachTrigger" and confirming "#H_Status_USBUsing" is OFF.
 
 
1.

When you connect a USB storage device to the display unit, "#H_Status_USBUsing" is turned ON.
2.

Turn on "#H_Control_USBDetachTrigger" When you remove a USB storage device.

3. "#H_Status_USBUsing" turns OFF automatically when a USB storage device can be removed.

NOTE

When "#H_Control_USBDetachTrigger" is ON while writing the data from the USB storage device, "#H_Status_USBUsing" does not turn OFF until data writing is completed.
 
Reference: Only right after a touch operator interface gets started, the error message, "RAAA013 USB storage  location not found" appears and the error status is stored in Status Address.
