Those settings are what I use. However, I have discovered a strange thing.
If I DISABLE ISQ assignment to the USB and disable the AC97 , then the
system seems to work. The and is inclusive, so both have to be disabled.
(I don't undersant the AC97, since it has nothing to do with it.)
What I mean by seems, is that now when I try to use the camera, it does
not accept any changes sent to it by , for example "echo
"compression_mode:none" >> /dev/proc/cpia/video0 ", which did work before
changing the motherboard. Also, if I use modprobe uhci, I never get any
pictures because it gives EOL errors for every request. If I use the
modprobe usb-uhci, I get extremely slow downloads because it constant
complains about :
usb-uhci.c: iso_find_start: gap in seamless isochronous scheduling
and sometimes
usb_control/bulk_msg: timeout
I get about 1 frame per three seconds on the average, where as I could
easily do 15 per second before.
Is is camera specific? Please help, as this is driving me crazy! any help
is appreciated and thanks alot.
