hello everybody !
I own a eci hifocus usb adsl modem, on a DFI AK75-EC socket A mobo (KT133A
chipset). I use usb_uhci with 2.4.19-xfs, compiled with gcc 3.2 on athlon-tbird
arch.
I've tried with usb_uhci as module and included same result. As I don't know if
it is due to usb routines ou driver I send a mail to both mailing-lists.
here is part of my /var/log/syslog:

1 warning issued. Results may not be reliable.
that's it. I'd be glad if anyone could help. This problem tends to appear about each
three days, when connection is lost (each 1440.1 minutes).
btw the way here is part of my kernel conf:
<*> Support for USB
[*] Preliminary USB device filesystem
<M> UHCI (Intel PIIX4, VIA, ...) support
and now part of pppd conf:

this is the end. sorry that was a bit wordy. if you have any other question feel
free to mail me. and please, CC me as i'm not suscribed to these MLs.
best regards,
laurent.
