Failed to connect UP 300 (USB)/USB transfer failed

When the UP 300 is connected with a USB cable, there is no prompt on the connection, and the software control operation can’t be performed.

Following possibilities for your reference,

1. USB cable is not fixed/loose; USB cable is damaged

• Check if the USB cable is damaged (damaged, connector deformed), and re-plug the USB cable on the mainboard and PC
• If the fault persists, replace the USB cable

      2. USB port on PC

• The USB interface of the connected PC may be damaged. Change the USB interface or check it with  another PC

     3. Software driver installation failed

• Connect the device to the PC with USB and update the UP300 driver in the PC device manager (drive location: software installation directory)

     4. Software version problem

• Download the latest control software from the designated official website

     5. PC mainboard is underpowered

• Change another PC (some MACs have experienced insufficient power supply to the mainboard and the symbol of “USB connection” always flashes when connecting, and eventually the connection is abnormal)

     6. Peripheral interface board damaged / display damaged / external interface board damaged

• Turn off the power and replace the peripheral interface board
• Turn off the power and replace the display
• Turn off the power and replace the peripheral interface board

     7. Screen signal/ power cable

• Turn off the power, and replace the screen signal/ power cable
