Problemi con i driver eciadsl

[danae20032001]

Salve a tutti. Sul pc della mia ragazza ho la 10.2 con il kernel 2.4.32. Lei dispone di una connesisone adsl con alice ed ha un modem ericsson HM120dp (supportato dai driver eciadsl). Ho installato dai sorgenti il pacchetto eciadsl-usermod-0.10 (la versione 11 che e' piu' recente da problemi di installazione) e i relativi binari di sincronizzazione eciadsl-synch_bin. Ho installato i pacchetti senza problemi e configurato i driver come dalla guida trovata sul sito. Il modem si collega ma la connessione e' altamente instabile nel senso che cade di continuo. Ho dato

che sembrano a posto. Qualche consiglio? che posso fare? Grazie.

E' un problema con il driver delle USB. Linux ha due drivers per le USB , uhci.o e usb-uhci.o, Slackware di default usa uhci.o che ha delle incompatibilita' con i driver eciadsl. Io ho risolto con questi comandi:

modprobe -r uhci
modprobe usb-uhci

dopo di cio' carica i driver del modem e prova la connessione.
Se E' tutto ok puoi mettere i comandi in rc.local

[danae20032001]

Ok tolgo i moduli che mi hai detto ma una volta tolti quali carico dopo? Grazie!

[percoco2000]

modprobe -r uhci
toglie il modulo

modprobe usb-uhci
inserisce il nuovo

[danae20032001]

Scusa la mia ignoranza ma come ho postato sopra se faccio lsmod mentre sono collegato vedo la riga

usb-ohci 19368 0 (unused)

mentre non trovo traccia del modulo ohci.....come mai? Se e' caricato dovrebbe vedersi invece mi risulta usb-ohci.....Ma sono moduli diversi? Perche' tu scrivevi usb-uhci e uhci.....non mi vede nessuno dei due! Grazie!

[percoco2000]

si, sono due implementazioni diverse del driver

[danae20032001]

Una curiosita': come mai se slackware usa i moduli uhci quando faccio lsmod non mi compare nessuno di questi moduli? Grazie.

[percoco2000]

Se non erro, in base all' hardware, viene usato uhci o ohci, e per queste ci sono due implementazioni. In piu' c'e' ehci (mi pare) per usb2.0
