bonjour,
j'ai un pb assez bizare avec le modem speedtouch, la connexion fonctionne
parfaitement (sous MDK8.2 et redhat 7.2) mais au bout d'un certain temps
variable (de 5 min � plusieurs heures) le modem s'eteint...je suis oblige de
faire un 'modprobe -r usb-uhci' puis de relancer le mod usb-uhci pour
pouvoir me reconnecter...je precise que tout fonctionne parfaitement sous
windows, la connexion tient plusieurs jours sans PB. J'ai une carte mere
intel dont le chipset usb est bien identifi� par linux...j'ai essay� sous
deux distrib et ca fait exactement la m�me chose...
Please help ! si quelqu'un a un id�e je suis preneur !
