Hi there,

On a p2 350 with 128mb ram, running FreeBSD 4.8 Release, I am keep 
getting the following error after being up for more than about 3 days.

> usb0: host controller halted

The only device on USB is an Alcatel Speedtouch ADSL modem (the old 
blue body part one) using the PPPOA port from the ports collection. I 
am running ppp in ddial mode so the connection should always be up. The 
documentation for the port said that it was good for 4.4, 4.6 and maybe 
5.0?

Does any one know of any reason why there may be a problem running it 
on 4.8, or any other explaination for the problem. I do remember having 
a problem like this last year under 4.4 so I doubt that the OS version 
is the problem. We have also found the modem a little unstable under 
Win2K.

Any ideas how to fix this? -  or even a work around?

Does any one know how I can power cycle the USB bus, I thought of a 
cron job to restart the modem once a day but when I kill modem_run and 
ppp manually, they won't come back up again without a reboot.

Thanks
