Ragazzi mi serve un altra volta il vostro aiuto praticamente ho un bel problema le porte USB non funzionano cioè accendo il pc attacco il mouse e funziona per 10 secondi e poi si spegne in quanto le porte USB non funzionano più poi lo devo riavviare e funziona per tipo 20 secondi e così via fin quando inizia a funzionare certe volte ci vogliono parecchi riavvi prima che funzioni. Io sinceramente non credo sia un problema hardware forse c'è un problema software potreste aiutarmi per piacere ? sono disperato so usare la tastiera per fare praticamente tutto ma per certe cose non si può serve per forza il mouse. Confido nel vostro aiuto grazie mille

Non scrivo per dare a te la soluzione , ma per consigliarti di aggiungere dati per dar modo ad altri di risolvere .
Inizia con un "lsusb" "lshw"

Ciao
St

Identico problema anche sul mio portatile.
Fino a 2 mesi fa, nessunissimo problema, ora tutte le 4 porte usb vanno e non vanno in maniera randomica.

Facendo un lsusb, mi rileva ovviamente le periferiche che ci sono collegate.
Ma quando le porte usb non vanno, non rileva nulla.

Facendo lshw:
