Bug Description
Binary package hint: yelp
Description: Ubuntu hardy (development branch)
Release: 8.04 (amd64)
Mainboard is based on amd690G chipset.
I have been trying to get my SUB DBV-tuner to work, I have consulted v4l-dvb-users list and drivers are compiled ok and TV-usb-card is initialized correctly.
But when i issue a scan i get these strange usb disconnects / reconnect errors in syslog:

I already tried to disable usb autosusbend with good no results (find some issues related to this with google):
put this in rc.local:
echo -1 > /sys/module/
sleep 1
/usr/sbin/lsusb
Is this is a kernel bug?
