As I said in a previous thread, I managed to make my dvb-t receiver (http://linuxtv.org/wiki/index.php/DVB_USB#WideView.2FYakumo.2FHama.2FTyphoon.2FYuan_Boxes_and_Pens) work.

I has worked under WindowsXP, and it also has worked very well under kubuntu breezy, using kaffeine.
But now, I don't know why, it doesn't work anymore. I tried on three different computers, running windows and/or linux.

Using kaffeine, I get these error messages :

Or using scan (inside dvb-apps package) :

etc ... etc ...
--------------------------------

It really seems broken as it neither doesn't work anymore under windows. Two, different computer under windows, and one with a clean, first install.

So, is it possible that the dvb-t receiver becomes broken after using it under linux ? Dunno how, maybe uploading the firmware or some weird commands ?

Thanks.
