Pendriv'y się rozłączają co chwile

[koperek18cm]

Witam

Często mi się przydarza na Ubuntu, że podczas włożenie pendrive do byle jakiego gniazda USB, to system go łączy, później rozłącza i znowu podłącza.. i tak może być w kółko.

Mam to samo z PSP, Pendrive ADATA i Kingstona.

Pozdrawiam

Po podłączeniu dysku przenośnego i zaobserwowaniu "rozłączania" uruchom konsole i wpisz polecenie dmesg. Podsystem USB pod linuksem zapisuje w logach systemowych informacje na temat podłączania/rozłączania urządzeń USB.
