Thank for the answers. > > Sure. Plug the device into a different port. The ports aren't all on > the same bus. There are 4 ports on the motherboard back. At each port, lsusb says the stick is plugged on BUS 1 (with different devices). Moreover when I plug my USB optical mouse on the same port, now the bus changes, it become bus 3! Is it normal that a same port can be assigned to several bus? Otherwise, where the problem can come from? Is a problem of the dibcom dvb-t usb with bad protocol, or a problem of sb700????
