In fact it seems that there are 2 usb2 bus. I change the connection between the front usb and the motherboard, and now my wifi stick is on bus 2. And now the dvb-t works perfectly at the same time than the wifi stick. That's good. In fact my problem seems closely related to this bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/256492. I was thinking that it was solved, but it doesn't seems. But I still do not understant why the 2 usb2 devices cannot share the same bus without interfering. Is there a way to test the usb connection, a kind of utility that test the usb connection?
