Hi all
I have previously had the Compro U500 USB running under FC6 using an older
version of the V4L DVB modules and the help of these fine people in this
mailing list.

On the last occasion, I simply changed the Compro U500 product ID in
"linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h"
from 1e78 to 1e82  then made and installed and loaded the modules.

However, I have just upgraded with a fresh install of Fedora 8 and puled
down the v4l-dvb source and changed the previous line as before but am
getting major issues as soon as I start dvbscan to test it.

There also is another Compro listed to cofuse me...

#define USB_PID_COMPRO_VIDEOMATE_U500                   0x1e78
#define USB_PID_COMPRO_VIDEOMATE_U500_PC                0x1e80

I have tried to change both IDs to 1e82 on two separate occasions with no
success.

It appears to work, successfully loading the firmware to a warm state, but
as soon as I dvbscan  get :

This shuts off my USB to make it unusable.
any ideas where to go from here? what other changes ,if any, are needed for
the source?
Any help at all would be appreciated.
Thanks
Craig
