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
