Raspberry pi_Failure in working

Raspberry pi_Failure in working

We have purchased 5 Raspberry pi´s, last week we tried to start using last one of them in the office but unfortunately it is not working.

As shown in the attached image, I am experiencing 2 issues:

  1. USB ports are not working. (tried all 4 ports to connect to the keyboard and also tried with different keyboards)
  2. Starting window is still. (for other 4 devices after clicking Ctrl+Alt+F12,  login screen pooped up but for this device screen is still)

 I believe these issues are due to not working USB ports.

 Could you please confirm the problem and help me to get it resolved?

 Thank you in advance. 😊
