[linux-dvb] Terratec DT USB XS Diversity/DiB0070+vdr: "URB status: Value too large for defined data type"+USB reset

[Marco Borm]

Hi folks.

Sorry but I'm unable to reply to my previous message, because I just 
don't have this message. Now I'm registered to both lists...

I "played" a little bit with my problem and tried the latest source from 
the repository, but EOVERFLOW still occurs seconds after starting vdr.
I activated the debug options of all, I hope, relevant modules now and 
got a more detailed kern.log.
Maybe some expert can help me and take look at it.
Interesting section:

Jun  1 23:16:14 vdr kernel: function : dvb_dvr_poll
Jun  1 23:16:14 vdr kernel: function : dvb_dvr_poll
Jun  1 23:16:14 vdr kernel: function : dvb_dvr_poll

Jun  1 23:16:14 vdr kernel: function : dvb_dvr_poll
Jun  1 23:16:14 vdr kernel: function : dvb_dvr_poll
BOOM -> Jun  1 23:16:14 vdr kernel: urb completition error -75.
