Hello, can you help me solve the following problems?
Once we have followed the following steps: "3.1 Enabling USB Mode After POS is turned on, USB mode is turned off by default. Setting -> About mobile phone click "client version" 5 times. It will prompt you for a message to turn USB mode on/off. Click Open to enable USB mode.
The QR LED and validator were disabled and we were unable to properly test the device and read the log via USB. Is there any way to connect via USB and keep the QR reader working?
