[mythtv-users] DVB-T Card (DViCO) stopped working on 14.04.1

[Ben Kelly]

I've just upgraded from mythbuntu 12.04 LTS to 14.04.1. The upgrade went
very smoothly, but one of my DVB-T cards is no longer working. I have two
DViCO cards in my system:
DViCO FusionHDTV DVB-T Plus - working
DViCO FusionHDTV DVB-T PRO - not working

This is the lspci for the broken DVB card, which looks good:

But this is what I see in dmesg when the system tries to register a
frontend device (ie: /dev/dvb/adapter0/frontend):


[   21.412769] cx88[1]/2: subsystem: 18ac:db30, board: DViCO FusionHDTV

[   21.417385] cx88[1]/2: dvb_register failed (err = -22)

[   21.417446] cx88[1]/2: cx8802 probe failed, err = -22


I've upgraded to the latest V4L drivers, but that hasn't helped. This card
was working perfectly under 12.04.


Any ideas ??


Thanks,


Ben
