Edit:
I got it!!! Together with the USB stick and ethernet cable the BV7 updated to 0.1.66. Strange, isnt' it?
Confirmed: It is not possible to update your dvb-hd module on bv 7 without having ethernet plugged in. The tv simply does not look for the USB stick unless the ethernet is plugged in.
Haha...another FAILURE from B&O.
