Ho acquistato due hub USB dal marchio cinese dodocool. Uno più piccolo senza porta Ethernet e uno più grande con Ethernet (DC50). Quello più piccolo funziona correttamente su MacBook Pro 15 2018, incluso HDMI. Quello più grande non è riconosciuto. Ho visto cosa succede quando lo connetto e questi messaggi sono comparsi nel registro:

Comunque funziona bene su Lenovo Carbon X1 sesto gen con Fedora 29, quindi l'hub sembra essere OK. Hai qualche idea se posso risolvere questo?
