[mythtv-users] DVB card disappearing UB 20.04LTS

[Alan]

Hi All

Recently had this issue pop up after upgrading to UB20.04 and v31. 
Appears the USB driver or hardware for the tuner disappears. Strangely I 
have also replaced the Nova T card as the old one was doing a similar 
thing just before the upgrade. The old one had run 247 with no issue for 
many years.

Is there a more friendly way of "resetting" the kernel after this so I 
don't have to reboot a couple of times a week? the reboot process is 
painfully slow after this and often doesnt actually come back until 
reset button!

Anyone had similar / any known issues with that card and 20.04?


Please help :(
