Estou tentando conectar um Vultech UPS1050VA-PRO ao meu novo Raspberry Pi 4 por meio do cabo USB fornecido, mas ele não aparece na saída lsusb (tentei conectá-lo às portas USB 2.0 e 3.0 do meu Raspberry Pi 4) . Também testei todas as portas USB conectando um pendrive USB e todas estão funcionando bem. Em vez disso, quando tento conectar o cabo UPS a um raspberry pi 2 antigo, o lsusb pode detectá-lo normalmente (veja abaixo)
onde foi que eu errei? desde já, obrigado
