[linux-dvb] Yuan EC372S no frontend

Hello,

I have some problems with a Yuan EC372S card. I am using the latest (rev
7499:1abbd650fe07) v4l-dvb from mercurial head. 

The card is correctly detected and the firmware loaded but no frontend
is attached to it.

I'm running kernel 2.6.22-14-generic on an Ubuntu Gutsy.

I have attached the relevant output of dmesg and lsusb -v and of course
I'll be glad to give more informations if needed.

Regards,
Julien
