Dopo aver funzionato per settimane - e che il Mostro Spaghetti
mi fulmini se ho cambiato qualcosa [1] - un simpatico modem
huawei E172 ha cominciato a morire dopo pochi minuti/secondi di
utilizzo.
Connesso tramite un cavo USB piuttosto lungo (4 o 5 metri, ma
dovremmo essere dentro le specifiche), ho tentato anche inserendovi
a meta` un hub usb _alimentato_, ma senza risultati.
Di seguito, il log del kernel (debug abilitato - feci anche un
tentativo sbattendo ad 1 /sys/module/usbcore/parameters/old_scheme_first)
Idee, consigli, conigli da sacrificare al dio dei bus balzani?
Ah, ho tentato a metterci una chiavetta USB e ravanare pesantemente
in scrittura/lettura contemporanee, e non ha fatto una piega.
Ri-ah, nel kernel CONFIG_4KSTACKS e CONFIG_USB_SUSPEND sono
disabilitati. Cosi` come CONFIG_USB_PERSIST (che non so se
possa servire).
(nota: qh128-0601 suppongo sia quel ciarpame di hub usb alimentato
che c'ho messo in mezzo).
